PHP - Storing Data In Php Or Xml Files?
I want to store a series of data which are called in a main php file. Do you suggest to store them in xml as
file1.xml: <title>TITLE</title> <content>CONTENT</content> or file1.php: $title="TITLE"; $content="CONTENT"; AND is it better to create separate file for each article or storing all data in one single file? Similar TutorialsHi, I am having a wierd problem and I dont know what is causing it - PHP/MySql.? Server - Apache on Fedora Php - 5.3.2 MySql - 5.1.47 In the same server config I have implemented storing files into blob fields any type of file by using mysql as well as mysqli. The one implemented by mysql is working just fine. But the one using mysqli is not working for anything other than text files. For image files the following error is coming - Error interpreting JPEG image file (Not a JPEG file: starts with 0x0a 0xff) For word/pdf etc the files are getting corrupted in such a way that the concerned application is not recognising it as a valid document. /*MySQL using mysql_connect Storing*/ $name=trim($_POST['fname']); $desc=trim($_POST['description']); $file=$_FILES['formfile']['name']; $filetype=$_FILES['formfile']['type']; $filename=$_FILES['formfile']['tmp_name']; $fileerror=$_FILES['formfile']['error']; $filesize=$_FILES['formfile']['size']; $fp = fopen($filename, 'r'); $content = fread($fp, filesize($filename)); fclose($fp); if (!get_magic_quotes_gpc()) { $content = addslashes($content); $name=addslashes($name); } $query="insert into forms_master (name, description, data, filename, filesize, filetype, entrydate) values ("; $query.="'$name', '$desc', '$content', '$file', '$filesize', '$filetype', now())"; /*Retreiving*/ $id=$_GET[sha1('id')]; $form=mysql_fetch_array(mysql_query("select filename, filesize, filetype, data from forms_master where sha1(id)='$id'", $link)); header("Content-length: ".$form['filesize']); header("Content-type: ".$form['filetype']); header("Content-Disposition: attachment; filename=".$form['filename']); print $form['data']; Works absolutely fine /*MySQL using mysqli_connect Storing */ $file=$_FILES['fname']; $name=$file['name']; $tmp_name=$file['tmp_name']; $size=$file['size']; $type=$file['type']; $fp = fopen($tmp_name, 'r'); $content = fread($fp, filesize($tmp_name)); fclose($fp); $content = mysqli_real_escape_string($link, $content); $name=mysqli_real_escape_string($link, $name); $query="insert into document_master (name, size, filetype, data) values ('$name', '$size', '$type', '$content')"; //Retreiving $id=$_GET[sha1('id')]; $file=mysqli_fetch_array(mysqli_query($link, "select name, size, filetype, data from document_master where sha1(id)='$id'")); header("Content-type: ".$file['filetype']); header("Content-length: ".strlen($file['size'])); header("Content-Disposition: attachment; filename=".$file['name']); print $file['data']; Note. I uploaded an image file through phpMyAdmin. Then tried to retreive it via the mysqli code above. The same error came. Any help will be greatly appreciated. I'm modifying a script I built a few months ago to allow someone to upload an attachment via a form and then email it off. It is expected that this form will receive a lot of hits and so it won't be possible to store the attachment in a folder before emailing it out (right away). Problem: If I skip the move_uploaded_file part, and just attach the tmp_name the tmp_name is how I receive it rather than the PDF that it actually is. How can i change the documents name before sending it off, without saving it to a general location. My worry with saving it is, someone uploads their copy and at the exact moment it's supposed to email off, someone somewhere else uploads theirs and it overwrites the first persons and then the email gets sent with the newest persons data. index.php Code: [Select] <form action="process.php" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" /> <br /> <input type="submit" name="submit" value="Submit" /> </form> process.php Code: [Select] <?php print_r($_FILES); if ($_FILES["file"]["type"] == "text/plain") { if ($_FILES["file"]["error"] > 0) { echo "Return Code: " . $_FILES["file"]["error"] . "<br />"; } else { echo "Upload: " . $_FILES["file"]["name"] . "<br />"; echo "Type: " . $_FILES["file"]["type"] . "<br />"; echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />"; echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />"; if (file_exists("upload/" . $_FILES["file"]["name"])) { echo $_FILES["file"]["name"] . " already exists. "; } else { move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]); echo "Stored in: " . "upload/" . $_FILES["file"]["name"]; } } } else { echo "Invalid file"; } ?> Can anyone tell me whats wrong with this: The file uploads fine, the url however does not get posted to the database? I added a 'or die' but it didn't execute...Do I need to move the query higher up the script? <?php include ('base.php'); $id = $_GET['id']; if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 20000)) { if ($_FILES["file"]["error"] > 0) { echo "Return Code: " . $_FILES["file"]["error"] .

The issue im havign will it be easier to just store all of this information into session variables and then save them into the database at the end when all of the details are ready ? Thank You Hey I am having a small problem with setting and storing data using $_SESSION for a login script to validate that a user is logged in. The outputted error message I'm getting is; Notice: Undefined index: userid ...\...\ Notice: Undefined variable: userid in ...\...\ The PHP code I'm using for the validation Code: [Select] <?php session_start(); //must call session_start before using any $_SESSION variables $username = $_POST['username']; $password = $_POST['password']; $userid = $_POST['userid']; //validating a user function validateUser() { session_regenerate_id (); //this is a security measure $_SESSION['valid'] = 1; $_SESSION['userid'] = $userid; } Let me know if you need any other bits of code to establish what is happening I really need help with this. Thanks. Hi, I have a XHTML/PHP page that loads a PHP file each couple of seconds for building up the page. The PHP file should retreive data that keeps changing. What would be the best way to store and retreive the data? Obviously i can do this with a database but that will put a lot of stress on the server as each user keeps polling the database. So i was looking into other methods of doing this. I have tried doing this with a plain text file and CSV files using fwrite to put the initial data into a file with separators. Then retrieving that file and explode it into a multidimensional array again. I am unsuccessful here to assign the key values to the new array. I have also tried many snippets for this but these where also not working properly for me. Maybe XML is the key, i didn't really delve into it yet but it seems i have to get extra programs or parser to actually write and change files? But then again i can't find any working tutorials on how to put multi dimensional strings back and forth between PHP and XML. So what needs exactly to be done. Well i'm creating a game where you can fight each other with 4 units on a turn base. The units have a speed stat that determines when it's there turn to act. Like if (unit 1) has 3 speed and (unit 2) 5 speed they will move like this on the time line (unit 1) -> (unit 2) -> (unit 1) -> (unit 1) -> (unit 2). So the plan is each time the user acts with a unit to increment it's speed by the base value. A script will run each time picking up the next unit in line. The PHP page does a check on which player the unit belongs to and if that matches the players ID it will sent the necessary information. The other player will get something like "not your turn". Tx, Here is my code... Code: [Select] <?php mysql_connect("localhost", "user", "pass")or die("cannot connect"); mysql_select_db("database")or die("cannot select DB"); $myemail = mysql_real_escape_string($_POST['myemail']); $mypassword = mysql_real_escape_string($_POST['mypassword']); $mypassword = md5($mypassword); $myemail = stripslashes($myemail); $mypassword = stripslashes($mypassword); $sql="SELECT * FROM users WHERE email='$myemail' and password='$mypassword'"; $result=mysql_query($sql); $count=mysql_num_rows($result); if($count==1){ session_start(); $_SESSION["myemail"]= "$myemail"; header("location:home.php"); } else { header("location:fail.php"); } ?> What can I do to this code so that it will also store first name from the database inside a session?

Hey everyone I'm pulling data from my db and then trying to store each value to its own var. the problem is the amount of values is always changing. here is what I have that isnt working $result = mysql_query("SELECT thismonth FROM list"); while($row = mysql_fetch_array($result)) { echo $row[0] . "<br>"; // this prints out all the values perfectly } no I just dont know how to store them so i can use them later. hi everyone, i just signed up on this forum. I have issue, my clients wants to save time by copying data into a textarea and then letting the script process it and store it in database. the problem is never done that. the data is made up for eg. Title Mr Name Radio86 Address Chiltren House etc.... how do i split this data up and store it in database, btw ive just started programming in php in other words newbie Please help me, thanks in advance Hi all I have a question about how to store parsed data into a multidimensional arrays -- I can store items into an array, but multidimensional arrays mystify me a bit. Any help would be greatly appreciated. I'm storing the images in a table, grouped according to their table and their descriptions, so that later when I call the images, I can display them accordingly. I'm using the Simple HTML DOM Parser. So say I have two tables, one with three images, and another with one. I'd like the resulting to array to look like: Code: [Select] Array ( [0] => Array ( [0] => image1.jpg [1] => 1st Variation Description ) [1] => Array ( [0] => image2.jpg [1] => image3.jpg [2] => image4.jpg [3] => 2nd Variation Description ) ) This is what I have so far: Code: [Select] $html = str_get_html($vartables); $varinfo = array(); foreach($html->find('table') as $table){ $varinfo[] = $table->innertext; } print_r($varinfo); Which yields: Code: [Select] Array ( [0] => <tr> <td width=150> Description1 </td> <td><a href="image1.jpg"> <img src="image1" height=100 border=1></a> </td> </tr> [1] => <tr> <td width=150> Description2 </td> <td><a href="image2.jpg"> <img src="image2.jpg" height=200 border=1></a> </td> <td><a href="image3.jpg"> <img src="image3.jpg" height=200 border=1></a> </td> <td><a href="image4.jpg"> <img src="image4.jpg" height=200 border=1></a> </td> </tr> ) I'd like to strip out the html and keep the .jpg's and descriptions together in a multidimensional array...unfortunately my newbness is getting the better of me there, I'm researching but running into a roadblock. Thanks in advance for any help. I am having some problems with part of the code. What is going on is a user registers info with a form and is sent an email with a confirmation link. The info that was in a temp DB table is moved to a member table. All of this works fine, but I am trying to be able to store an ID and username associated with their passkey info and echo that variable out. This part I am having trouble with. Code is here. <? session_start(); include('config.php'); // Passkey t from link $passkey=$_GET['passkey']; $tbl_name1="Profile_temp"; // Retrieve data from table where row matches passkey $sql1="SELECT * FROM $tbl_name1 WHERE confirm_code ='$passkey'"; $result1=mysql_query($sql1); // If successfully queried if($result1){ // Count how many row has this passkey $count=mysql_num_rows($result1); // if passkey is found retrieve info from temporary DB if($count==1){ $rows=mysql_fetch_array($result1); $FirstName=$rows['FirstName']; $LastName=$rows['LastName']; $UserName=$rows['UserName']; $Password= md5($rows['Password']); $Password2=md5($rows['Password2']); $email=$rows['email']; $Zip=$rows['Zip']; $Birthday=$rows['Birthday']; $Security=$rows['Security']; $Security2=$rows['Security2']; $tbl_name2="Profile"; // Insert data that retrieves from "temp_members_db" into table "registered_members" $sql2="INSERT INTO $tbl_name2(`FirstName`,`LastName`,`Username`,`Password`,`Password2`,`email`,`Zip`,`Birthday`,`Security`,`Security2`) VALUES ('$FirstName','$LastName','$UserName','$Password','$Password2','$email','$Zip','$Birthday','$Security','$Security2')"; //echo $sql2; $result2=mysql_query($sql2); } // if passkey is not found, display message "Wrong Confirmation code" else { echo "<h2>Sorry, Your passkey was not found.</h2>"; } while ($row = mysql_fetch_assoc($result2)) { $_SESSION['id'] = $row['id']; $_SESSION['UserName']=$user_name; } // if successfully moved data from table"temp_members_db" to table "registered_members" displays message "Your account has been activated" and don't forget to delete confirmation code from table "temp_members_db" if($result2){ echo "<h2>Your account has been activated, </h2>"; echo "$user_name"; echo"<p>You may now upload a profile picture</p>"; // Delete information of this user from table "temp_members_db" that has this passkey $sql3="DELETE FROM $tbl_name1 WHERE confirm_code = '$passkey'"; $result3=mysql_query($sql3); } } ?> getting an error for this part while ($row = mysql_fetch_assoc($result2)) { $_SESSION['id'] = $row['id']; $_SESSION['UserName']=$user_name; } the error is "Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in confirmation.php on line 62" This is more of a database architect question.
I am building a CMS for website development. I am ready to use it for the first time on one of my clients. Now, my issue is is how to set up some or one of my table(s) for some areas that my client wants to be able to change in the admin section.
In their website on the front page, I put together this nice block slider. Its 6 blocks with text, a background image and nice effects. At first it was always going to be static, which was no issue at all, but later they came to me and asked if they could be able to change words in the boxes themselves in the admin section..
Of course this can be easily done by creating a table that is associated with this home page block thing and each row in the table will correspond to one of the blocks on the home page.
But I believe there might be an easier way to store this type of data without having to create another table for every feature the client wants to edit, for example they also want to be able to edit a slider on another page.
The WordPress database then came into my mind and how they store most of their data as JSON. So I was then thinking of creating a table named 'modules' for examples with three columns (id, title, data). Then inside the data column store the editable fields as a JSON string object.
For example a row could like like :
1, "Front Page Box Slider", {"slider-home" : [ {"data" : "value", "img_1", "value1"}, {"data" : "value", "img_2", "value2"} ]}
I've been doing a bit of research on this and people have just been saying, never do this if you do want your data to be searched through, which I don't.
Can anyone tell me why or why not I should do this, or maybe a better solution to my problem?
Thank you

I have added a "Remember me" checkbox into login form. I want to validate Boolean value using Javascript Checked property and send the data to PHP for validation.
If user clicks on remember me checkbox then the data should be stored in either Sessions & Cookies. If it is not checked then data should be stored only in Sessions. I am posting here my login form code, Ajax code & PHP code.
Could you guys help me to point out my mistake what I am doing wrong in this code?
Login Form:
<input type="checkbox" id="cb" name="cb"> <label for="cb">Remember me</label>Ajax Code:
function login(){var e = _("email").value;
var pass = _("password").value;
var cb = _("cb").value;
if(e == "" || pass == ""){
_("status").innerHTML = "Please fill out the form";
} else {
_("loginbtn").style.display = "none";
_("status").innerHTML = 'please wait ...';
var ajax = ajaxObj("POST", "handlers/login_handler.php");
ajax.onreadystatechange = function() {
if(ajaxReturn(ajax) == true) {
if(ajax.responseText == "login_failed"){
_("status").innerHTML = "Login failed, please try again.";
_("loginbtn").style.display = "block";
} else {
window.location = "message.php?msg=Hello "+ajax.responseText;
}
}
}
ajax.send("e="+e+"&pass="+pass+"&cb="+cb);
}
}
PHP Code:
$cb = cleanstr($_POST['cb']);
if(isset($cb) && ($cb == true)) {
// IF USER CLICKED ON REMEMBER ME CHECKBOX CREATE THEIR SESSIONS AND COOKIES
$_SESSION['userid'] = $db_id;
$_SESSION['username'] = $db_username;
$_SESSION['password'] = $db_pass;
setcookie("id", $db_id, strtotime( '+30 days' ), "/", "", "", TRUE);
setcookie("user", $db_username, strtotime( '+30 days' ), "/", "", "", TRUE);
setcookie("pass", $db_pass, strtotime( '+30 days' ), "/", "", "", TRUE);
// UPDATE THEIR "IP" AND "LASTLOGIN" FIELDS
$sql = "UPDATE users SET ip='$ip', lastlogin=now() WHERE id='$db_id' LIMIT 1";
$query = mysqli_query($con, $sql);
echo $db_username;
exit();
} else {
// IF USER HAS NOT CLICKED ON REMEMBER ME CHECKBOX CREATE THEIR SESSIONS ONLY
$_SESSION['userid'] = $db_id;
$_SESSION['username'] = $db_username;
$_SESSION['password'] = $db_pass;
// UPDATE THEIR "IP" AND "LASTLOGIN" FIELDS
$sql = "UPDATE users SET ip='$ip', lastlogin=now() WHERE id='$db_id' LIMIT 1";
$query = mysqli_query($con, $sql);
echo $db_username;
exit();
}
hi, I have created a login page this is my code <?php if (!isset($_SESSION)) { session_start(); } $host="localhost"; // Host name $username="root"; // Mysql username $password=""; // Mysql password $db_name="Marketing"; // Database name $tbl_name="Marketinglogin"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); $myusername=$_POST['myusername']; $mypassword=$_POST['mypassword']; // To protect MySQL injection (more detail about MySQL injection) $myusername = stripslashes($myusername); $mypassword = stripslashes($mypassword); $myusername = mysql_real_escape_string($myusername); $mypassword = mysql_real_escape_string($mypassword); $sql="SELECT * FROM Marketinglogin WHERE username='$myusername' and password='$mypassword'"; $result=mysql_query($sql); // Mysql_num_row is counting table row $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1){ // Register $myusername, $mypassword and redirect to file "login_success.php" session_register("myusername"); session_register("mypassword"); if ($myusername == "sandeep") { header("location:Marketingadmin.php"); } else { header("location:Marketingemployeeform.php"); } } else { echo "wrong password"; } ?> Marketingemployee form has some fields..here when we click submit button all the fields as well as the loginusername has to be stored in the database <?php if (!isset($_SESSION)) { session_start(); } $con = mysql_connect("localhost","root", ""); if (!$con) {die('Could not connect to DB: ' . mysql_error() );} mysql_select_db ("Marketing", $con); $date = $_POST['year'].$_POST['month'].$_POST['dt'] ; $_SESSION['myusername']=$_POST['myusername']; $myusername=$_SESSION['myusername']; $sql="INSERT INTO Marketingemployeetable (Employeeid, Date,Sector,Place,Contactpersonname,Contactaddress,Mobileno)VALUES ( '$myusername','$date','$_POST[project]','$_POST[place]','$_POST[Contactpersonname]','$_POST[Contactaddress]','$_POST[Mobileno]')"; if (!mysql_query($sql,$con)) {die ('Error: ' . mysql_error());} echo "Record added"; mysql_close($con)?> please help me out here To me it is logical to store config data such as site name, meta, etc in a php file rather than storing ina table in mysql database. This will reduce the number of calls to the mysql database, as these are key parameters and needed in every page. But, a well-developed CMS like Wordpress uses a mysql table to store such basic data. What is your idea? Ain't it better to reduce mysql loads? I have a user registration page that requires the user to input a Username, Password, Confirm Password, Email. If the user passes all the validation requirements for the new account, I then need to have the username, password, email fields saved to a file called 'login.dat'
Here is my code that I have so far, it runs perfectly.
<?php
include 'helpfulfunctions.inc';
include 'productsdata.inc';
$user_login_file = 'login.dat';
//var_dump($_POST);
// product data for photo, name, and price.
$alluserinfo = load_users_info($user_login_file);
//validate users info
$errors = array();
if (array_key_exists('register_submit', $_POST)) {
//check to see if username is taken
$username_entered = $_POST['username'];
//check to see if username already exists
if (array_key_exists($username_entered, $alluserinfo)) {
$errors['username']['username_exists'] = "Username already exists.";
}
//validate username is 4-11 characters long using only a-z A-Z 0-9
if(preg_match("/^[0-9a-zA-z]{4,11}$/",$_POST['username']) ===0){
$errors['username']['invalid_username']= "Invalid username. Username must be 4-11 characters long and use only letters and numbers.";
}
//validate password "." means any character
//.* allows numbers 0-9 to be inserted anywhere
//?= positive lookahead: next text must be like this and follow these rules
// must be at least 6 characters, contain 0-9, a-z, A-Z
$pw_entered=$_POST['password'];
if(preg_match("/^.*(?=.{6,})(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z]).*$/", $_POST["password"]) === 0){
$errors['password']['invalid_password']="Password must be at least 6 characters and must contain at least one lower case letter, one upper case letter and one digit.";
}
//validate that "confirm password" matches password above
$pw_repeat=$_POST['confirmpassword'];
if($pw_repeat != $pw_entered){
$errors['confirmpassword']['pw_no_match']="Passwords do not match. Try again.";
}
//validate email format
$email_entered=($_POST['email']);
if(!filter_var($email_entered, FILTER_VALIDATE_EMAIL)){
$errors['email']['invalid_email']="Not a valid email. Please try again.";
}
//no validation errors=>print invoice
if (empty($errors)) {
include 'invoice.inc';
exit;
}
}
//reprint if invalid entry. if no errors print invoice
?>

In case it's needed, this is the 'helpfulfunctions.inc' file and the included functions:
<?php
if (!function_exists('load_users_info')) {
function load_users_info($users_data_file) {
$fp = fopen($users_data_file, 'r');
//read all lines of login.dat file and create user info arrays
while (!feof($fp)) {
$users_info_line = fgets($fp);
$user_info_parts = explode(',', $users_info_line);
$user_info_array = array('username' => $user_info_parts[0], 'password' => $user_info_parts[1], 'email' => $user_info_parts[2]);
$complete_user_info_array[$user_info_array['username']] = $user_info_array;
}
fclose($fp);
return $complete_user_info_array;
}
}
// function to display products
if (!function_exists('display_products')) {
function display_products($products_to_display, $quantities = array()) {
global $errors;

<?php
// quantities are 0 unless already inputted, if quantities previously were inputted, return the values.
// input boxes
for ($i = 0; $i < count($products_to_display); $i++) {

Can anyone help me out?
hello dear php-experts,
https://europa.eu/youth/volunteering/organisations_en#open
<?php
// Report all PHP errors (see changelog)
error_reporting(E_ALL);
include('inc/simple_html_dom.php');
//base url
$base = 'https://europa.eu/youth/volunteering/organisations_en#open';
//home page HTML
$html_base = file_get_html( $base );
//get all category links
foreach($html_base->find('a') as $element) {
echo "<pre>";
print_r( $element->href );
echo "</pre>";
}
$html_base->clear();
unset($html_base);
?>
I have the above code and I'm trying to get certain elements of the page but it isn't returning anything.
Is it possible that certain PHP functions might be disabled on the server to stop that? The above code works perfectly on other sites.
Is there any workaround?
btw: i have created a small snipped as a proof of concept to run this with Python and BeautifulSoup -
import requests
from bs4 import BeautifulSoup
url = 'https://europa.eu/youth/volunteering/organisations_en#open'
response = requests.get(url)
soup = BeautifulSoup(response.content, 'lxml')
print(soup.find('title').text)
block = soup.find('div', class_="eyp-card block-is-flex")
and this....
European Youth Portal
>>> block.a
<a href="/youth/volunteering/organisation/48592_en" target="_blank">"Academy for Peace and Development" Union</a>
>>> block.a.text
'"Academy for Peace and Development" Union'
>>> block.select_one('div > div > p:nth-child(9)')
<p><strong>PIC:</strong> 948417016</p>
>>> block.select_one('div > div > p:nth-child(9)').text
'PIC: 948417016'
what is aimed in the end - i want to gather the first 20 results of the page - and put them in to a sql-db or alternatively show the information in a little widget I am developing a database app for a client who needs to import hundreds of thousands of codes into the DB to check against. The codes are in 4 text files about 30MB each. The codes are 3 per line, then a line break, and 3 more. Ive written a script to parse out the line breaks, turn the data into an array, then loop over thay array and insert into the DB. The problem is these scripts take minutes to run using file_get_contents and by the time the data is ready the mmysql connection is gone. Plus even these files only work after Ive cut the files into about 1MB each, so each file is 30 smaller ones. Is there a way to just put the text file on the server, and have php search it using a GREP like function that won't be such a burden to work with. Any advice helps. James |
