PHP - Trying To Use Variables From Another File Out Of Memory
Hi, I am trying to create a login system in PHP, but I am not the greatest at PHP so I am using a source code which I found online as I found it to be more secure as it uses things like salted passwords. Anyway I am trying to add more fields to the register system so it adds them to the mysql, the source has a way to do this with arrays, but it is quite complicated so I am just using variables from the original file. There are 2 files: register.php and class.loginsys.php which contains all the functions. At first the query syntax was incorrect so I decided to use the variables created in register.php in the class.loginsys, but now it's giving me an out of memory error:
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 28672 bytes) in C:\xampp\htdocs\ls\class.loginsys.php on line 34 Which I am unsure of how to fix. I have tried using different variable names, checking the line, checking the whole register.php file for anything rogue. Here is the code: Top part of register.php <?php include "config.php"; ?>Config.php: <?php require "class.loginsys.php"; $LS=new LoginSystem(); ?>Then actual register part from register.php:
<?php
if( isset($_POST['submit']) ){
$firstname2 = $_POST['firstname'];
$lastname2 = $_POST['lastname'];
$user2 = $_POST['username'];
$sex2 = $_POST['sex'];
$country2 = $_POST['strCountryChoice'];
$email2 = $_POST['email'];
$pass2 = $_POST['pass'];
$pass3 = $_POST['pass2'];
$birthdate2 = $_POST['birthdate'];
$created2 = date("Y-m-d H:i:s");
//need to add a lot more validation functions.. AKA Check if email exists and username. Password > 5 chars
if( $user2=="" || $email2=="" || $pass2=='' || $pass3=='' || $firstname2=='' || $lastname2=='' || $sex2=='' || $country2=='' || $birthdate2=='' ){
echo "Fields Left Blank","Some Fields were left blank. Please fill up all fields.";
exit;
}
if( !$LS->validEmail($email2) ){
echo "E-Mail Is Not Valid", "The E-Mail you gave is not valid";
exit;
}
if( !ctype_alnum($user2) ){
echo "Invalid Username", "The Username is not valid. Only ALPHANUMERIC characters are allowed and shouldn't exceed 10 characters.";
exit;
}
if($pass2 != $pass3){
echo "Passwords Don't Match","The Passwords you entered didn't match";
exit;
}
$createAccount2 = $LS->register($user2, $pass2,
array(
"email" => $email2,
"name" => $firstname2,
"lastname" => $lastname2,
"gender" => $sex2,
"country" => $country2,
"DOB" => $birthdate2,
"created" => date("Y-m-d H:i:s") // Just for testing
)
);
//$createAccount = $LS->register($firstname,$lastname,$user,$sex,$country,$email,$pass,$birthdate,$created);
if($createAccount2 === "exists"){
echo "User Exists.";
}elseif($createAccount2 === true){
echo "Success. Created account.";
}
}
?>
And the function from the class:
/* A function to register a user with passing the username, password and optionally any other additional fields. */
public function register( $id, $password, $other = array() ){
if( $this->userExists($id) && (isset($other['email']) && $this->userExists($other['email'])) ){
return "exists";
}else{
$randomSalt = $this->rand_string(20);
$saltedPass = hash('sha256', "{$password}{$this->passwordSalt}{$randomSalt}");
if( count($other) == 0 ){
/* If there is no other fields mentioned, make the default query */
//old query: ("INSERT INTO `{$this->dbtable}` (`username`, `password`, `password_salt`) VALUES(:username, :password, :passwordSalt)");
//new query: ("INSERT INTO `{$this->dbtable}` (`username`, 'email' , `password`, `password_salt` , 'name' , 'lastname' , 'gender' , 'country' , 'DOB') VALUES(:username, :email, :pass, :passwordSalt, :firstname, :lastname, :gender, :country, :DOB)");
$sql = $this->dbh->prepare("INSERT INTO `{$this->dbtable}` (`username`, `password`, `password_salt`) VALUES(:username, :password, :passwordSalt)");
}else{
/* if there are other fields to add value to, make the query and bind values according to it */
//old query: ("INSERT INTO `{$this->dbtable}` (`username`, `password`, `password_salt`, $columns) VALUES(:username, :password, :passwordSalt, :$colVals)");
//new query: ("INSERT INTO `{$this->dbtable}` (`username`, 'email' , `password`, `password_salt` , 'name' , 'lastname' , 'gender' , 'country' , 'DOB') VALUES(:username, :email, :pass, :passwordSalt, :firstname, :lastname, :gender, :country, :DOB)");
$keys = array_keys($other);
$columns = implode(",", $keys);
$colVals = implode(",:", $keys);
//l= $this->dbh->prepare("INSERT INTO `{$this->dbtable}` (`username`, `password`, `password_salt`, $columns) VALUES(:username, :password, :passwordSalt, :$colVals)");
//INSERT INTO MyGuests (firstname, lastname, email)cLUES ('John', 'Doe', 'john@example.com')
$sql = $this->dbh->prepare("INSERT INTO `{$this->dbtable}` (username,email,password,password_salt,name,lastname,created,gender,country,DOB) VALUES ('$username2','$email2','$pass2','$saltedPass','$firstname2','$lastname2','$created2','$gender2','$country2','$birthdate2')");
print($sql);
foreach($other as $key => $value){
$value = htmlspecialchars($value);
$sql->bindValue(":$key", $value);
}
}
/* Bind the default values */
$sql->bindValue(":username", $id);
$sql->bindValue(":password", $saltedPass);
$sql->bindValue(":passwordSalt", $randomSalt);
$sql->execute();
return true;
}
}
Thanks for your help. I am doing this because for a hobby I am trying to create a browser based game in which I use this login system to login the user to a main page then code all of the other pages myself. I have posted on stackoverflow and someone on their suggested that I should use a framework. If this is the case, can someone point me in the right direction?
Thanks again, if you need any info ask.
Similar TutorialsI have this method that puts files into a zip file from an array list, it looks like this: public function zip($files = array(), $maxMB = 2, $flag = ZIP_NEW){ $this->memory_size = $maxMB * 1024 * 1024; $zip_id = $this->zip_id; $this->zip[] = new ZipArchive(); $this->zip_id++; if($flag == ZIP_NEW){ $open = $this->zip[$zip_id]->open("php://temp/maxmemory:$this->memory_size", ZipArchive::CREATE); $files = (array)$files; if(!empty($files)){ foreach($files as $file){ if(is_file($file)){ $this->zip[$zip_id]->addFile($file); } } } $this->zip[$zip_id]->close(); } $this->function_name = __FUNCTION__; return $this; } I then download them like this: public function download($download_data, $download_name, $type = DOWNLOAD_FILE){ header("Pragma: public;"); header("Expires: 0;"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0;"); header("Content-Type: application/force-download;"); header("Content-Type: application/octet-stream;"); header("Content-Type: application/download;"); header("Content-Transfer-Encoding: binary;"); header("Content-Disposition: attachment; filename=$download_name;"); if($type == DOWNLOAD_FILE){ header("Content-Length: ".filesize($download_data).";"); if($download_data == PHP_MEMORY){ $handle = fopen(PHP_MEMORY."/maxmemory:$this->memory_size", 'r+'); echo stream_get_contents($handle); }else{ readfile($download_data); } }elseif($type == DOWNLOAD_STRING){ header("Content-Length: ".mb_strlen($download_data).";"); echo $download_data; } $this->function_name = __FUNCTION__; return $this; } When I run this code: $files = array("file1.php","file2.php"); $live->zip($files)->download(PHP_MEMORY, "download.zip"); It downloads the file, the only problem is, is that when I open the file I get an error saying the file can not be opened. I know when I actually save it to a file instead of in memory it works. So, I am not sure if it isn't working in the download portion or the create file portion, as I have never worked with php://temp before. Any thoughts on why this doesn't work when using php://temp? Hi. I am working with some rather large files. Sometimes I am just opening a file and trying to find an entry on a single line. Sometimes I am opening a file and working on each line.
Whats the most efficient way to work with a large file?
If I open a file, and place all lines into an array, I will use a lot of memory.
If I open a file, and work on it line by line, I should use much less memory, but will the process take longer?
Whats most efficient?
I have underlined my main question above.
Thanks :-)
This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=359179.0 So here is what I have going. #1 - My weather station software processes a file and enters variables and then uploads it as a php file. #2 - Currently the station also just uploads every file to the site and enters the data in the html, but I would rather have it only upload this one file and the other pages grab data from it and print it out. I have a few php scrips in there to preform certain functions (if temp <= 32 it echos that data in blue and so on) but would rather make most of it php so I have less files being uploaded every 5 minutes. This is what the station sends to the web, but I have no idea how to get the other pages to read it and input the variables from it. Right, so I've made a very simple web app that allows.... 1.) People to register (adding them to the MySQL database) 2.) Login (providing they're in the database) I've gotten it all working, but I'm stuck at the last hurdle. If someone logs in using the correct username and password, it takes them to login_success.php. Here I query the database and use "SELECT * FROM Users WHERE Username = '$name'" I would have thought, that it would have returned that user's entry in the database. But instead I just get a blank page. Am I right in thinking that's because the contents of the $name variable aren't passed from log.php to login_success.php If so, how do I fix it? ---------------------------------------------------------------------------------------------------- LOGIN.PHP Code: [Select] <?php include_once "Common/header.php"; session_name("MyLogin"); $page = (isset($_GET['login']) ? strtolower($_GET['login']) : NULL); if($page == "failed"){ print $_GET['cause']; } ?> <div id="main"> <br />   <br />  <br /> <h2>Sign In</h2>   <form name="form1" method="post" action="log.php?action=login"> <b>Username:</b>  <input type="text" name="uname"/><br />  <br /> <b>Password:</b>                 <input type="password" name="pword" /><br />  <br /> <input type="submit" value="submit" /> </form> <?php include_once "Common/footer.php"; ?> LOG.PHP Code: [Select] <?php session_name("MyLogin"); session_start(); if($_GET['action'] == "login") { $conn = mysql_connect("localhost", "root", ""); $db = mysql_select_db("test"); $name = ($_POST['uname']); $word = ($_POST['pword']); $sql = "SELECT * FROM Users WHERE Username='$name' and Password='$word'"; $q_user = mysql_query($sql) or die(mysql_error() .

I can echo out the 1st variable correctly, but as soon as I add the second I just get Code: [Select] allow-nether= level-name= The variables $nether and $lname exist and I have echo'd them to check. I guess this is a formatting problem, just cant work it out! So say I have a file with the contents.. Code: [Select] ; this is a comment var2 : variable ; another comment var3 : file.txt how would I be able to do <?php echo $var2; ?> That would echo "variable" and <?php $file = file($var3); ?> So its reading the file to get the variable from the text file and if the line starts with ";" its disregarded.. Thanks
I have a php file with a bunch of variables declared. I now need a function to put data on a separate page that pulls variables from the required page.
<?php
function getplayer($position)
{ // start function
//$new_position = "$" . $position;
$new_position = $position;
$file = "their.php";

$db_select_their = "bschultz_their";
$servername = "localhost";
$username = "user";
$password = "pass";
$dbname = "db_name";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM (select number as position_number, name as position_name, pronunciation as position_pronunciation, pos as position_pos, height as position_height, weight as position_weight, year as position_year, city as position_city, state as position_state, notes as position_notes FROM $db_select_their WHERE name = '$new_position') as position";

$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row

For example: I am using this code: Code: [Select] $myFile = "newuser.txt"; $fh = fopen($myFile, 'r'); $theData = fread($fh, 5); fclose($fh); echo $theData; and it displays: Code: [Select] Bob 2 Which I am reading from my newuser.txt file! Which corresponds to the username bob, and he has the ID of 2. Now I want to make that linkable like this: Code: [Select] <a href=.?act=Profile&id=$IDFROMTEXTFILE(2)>$NAMEFROMTEXTFILE(BOB)</a> this is possible? If so, Thanks! So I have a text file "name.txt" in the text file I have ids and auth keys set up like this 1234564 abcdfhu 3123900 sdkoao etc How could I make it to where the ids are $ids and the auth keys are $auth_keys? I've tried using foreach() but I cant get it It's been a while since I've dealt with text files and currently I am unable to write the contents of a variable to a text file, only the literal is being written. Should I be de-referencing or is this even possible? Also the problem is compounded by the fact that i also want to write the contents of a class display function into the text file. Hello all, I am trying to create a PHP CLi Script that will help me setup new config and server files / directories for every new web project i get instead of me having to manually create everything with each project. The script accepts the project name, and y/n for whether i want to create subdomains for css, jss and image files. After it has that, it must create a new http config file under sites-available (in Linux), by pasting the config file text. Problem : If I output regular text to the file, it displays exactly in the format that I write the string variable. But when I use a printf, or try to use variables directly in the config text, it starts formatting the text in the config file in a strange way. I just want the variables to just be replaced and the text to appear in the exact format below. The text displays perfectly as i typed below in the config file if I don't use any variables. $subDomainConfig .= '<VirtualHost *:80> ServerAdmin webmaster@%1$s ServerName %1$s.%2$s ServerAlias %1$s.%2$s # Indexes + Directory Root. DirectoryIndex index.html index.php DocumentRoot /var/www/%2$s/public_html/ # CGI Directory ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Location /cgi-bin> Options +ExecCGI </Location> # Logfiles ErrorLog /var/www/%2$s/logs/apache/error.log CustomLog /var/www/%2$s/logs/apache/access.log combined </VirtualHost> '.PHP_EOL; $httpConfigFileText = sprintf($subDomainConfig, $subDomain, $shortProjectName); The above code outputs text in this way in the file : <VirtualHost *:80> ServerAdmin webmaster@images ServerName images.mysite ServerAlias images.mysite # Indexes + Directory Root.

I need help I am a new php user, and am trying to understand how to read a .txt file into an array then to retrieve the index of the array at will. Code: [Select] <?php //echo $myfile = fopen("ArrayTestFile.txt", "r") . "File exists: " or die("File does not exist or you lack permission to open it! "); //echo "The contents of the file is " . file_get_contents("ArrayTestFile.txt") . "<br />"; $fh = fopen("ArrayTestFile.txt", 'r+') or die("Failure"); $array = array(); //creation of array $num = fgets($fh);// recursive call variable $num fgets(.txt line) for ($i = 0; $i <= 5; $i++) //for loop loads first 5 of .txt { $array["i"] = $num; //loads each line of .txt into the array at the loops index. echo "Line " . $i . " of the array is " . $array["i"]; // displays the contents of the array in a print message } ?> Thank you. MOD EDIT: code tags added. Hello. Trying to learn MVC better by creating my own little framework to understand how it works. Things were going OK til now. I have a base class: <?php /** * Base class most classes will extend from. * Simply put, this class just has methods that * most, if not all, classes will need. */ class Application { public function includer($path) { if (is_readable($path) == true) { include_once($path); } else { die("404 not found =["); } } } ?> So the above method 'includer' just sees if a file exists/is readable and if so, include it. Here's where I am using said method. class Index extends Application { function __construct($method = 'view') { // load the index model include(ROOT . '/app/models/model.index.php'); // Invoke requested method. $this->$method(); } public function view() { $name = 'Smith'; $this->includer(ROOT . '/app/views/view.index.php'); # Problem here, i think } } view.index.php just contains <?php echo $name; ?> All that is called from the index page, with this line of code Application::includer($controller_path); Now, in line $this->includer(ROOT . '/app/views/view.index.php'); # Problem here, i think If i get rid of $this->includer, the script will work and say 'Smith'. If i have $this->includer(...) or parent::includer(...), it doesn't work. why? I am trying to pass a variable from inside of a function in a file that is included eg include.php Code: [Select] <? function noms(){ $foobar = "apples"; } ?> main.php Code: [Select] <? include("include.php"); noms(); echo "these ". $foobar. " are most delicious... OM NOM NOM"; ?> I am essentially using a include file for a mysql connection and based on the connection outcome i am either setting a value to true or false. It prints "Connected succesfully" and what not just fine, but, after that it wont pass on the variables data. I know its the function because, it passes the data if i put the variable before the function... i just dont get it.. any help would be great. Thanks. Ansel Just how big can i make this ? Im sure it depends on the server hardware and if thats the case then how does one fidn out how big I can make this. I want to max it out. -SB I am in the midst of developing a web application and despite having a decent amount of experience in web development, I never really stopped and gave a ton of thought to memory when it comes to my php scripts. However, with this project I am using zend framework and it is a decent memory hog. So I have some questions... I am monitoring my memory use for a typical call to my site and it appears as though its somewhere around 20MB. This seems like a ton and I am actively looking for ways to decrease it. One thing I noticed is that when I call zend's date class for the first time, my memory usage shoots up 3MB. However it is pretty much untouched for other instances of this class. So if I do Code: [Select] echo(memory_get_usage()); echo('<br />'); $this->last_login=Zend_Date::now(); echo(memory_get_usage()); echo('<br />'); $this->last_active=Zend_Date::now(); echo(memory_get_usage()); echo('<br />'); The result is Quote 9136448 12812408 12814496 So the jump is with that first call. My question is, if two users are accessing the site at the same time, will they both experience that 3MB memory use? Or will the server have that class in memory so it only uses 3MB once? Basically, if a call to the site uses 20MB of memory, will it be 20MB * the number of users. Or will the server have a lot of the information loaded into memory to subsequent calls so multiple users would use up far less memory then the initial? I would assume the latter is the case based on the fact that reusing zend_date doesn't incur a 3MB hit every time. But without being admin of my server and hvaing tons of folks to test at once, its hard to tell. Hey guys i have been making a website where friends can post on each others profiles like facebookish anyways im not sure if this is th ebest way to do it but i have this below its part of the code that pulls all the friends of the member from the database:: $query_friend = mysql_query("SELECT my_id,friend_id FROM site_friends WHERE my_id='$my_id'"); while($row = mysql_fetch_assoc($query_friend)){ $friend_id = $row['friend_id']; } then i pass it into a function blah blah not got that for yet anyway what happens if this person ends up having 100s of friends will this be harsh on the servers memory? or should i not worry to much ? hope someone can help thanks!! Hello Guys, I wanted to know what is memory leakage? Where we have to takecare of ? How to avoid this thing? What happens if you do not unset an array before the script is done executing? I am running through thousands of CSV files, parsing data for hundreds of thousands of customers. It works fine for the first 5/6 hours then starts bogging down bad. I run about 5-10 CSVs per execution...I'm wondering if unsetting the arrays in the script would help this or not...I thought they would be unallocated after the script ends. Am I wrong? |
