PHP - Weird Sh*t - Working With Integers And Strings
i hit a wtf moments
print $_POST['idName']; // prints 0, correct, the value of the selected select element item is indeed 0 print '<br>'; $value = intval($_POST['idName']); // otherwise its a string if($value == 'empty') { print '<br>wtf does this get printed?'; } the $values value is the number zero, not the string 'empty', so why does it eval as one? Similar TutorialsOn all my forms, after I send an empty string to one field, it will stop accepting values when I resubmit. My code passes through the W3C validator Any ideas?? Hi guys !. My name is AGustin and I live in argentina. Just wanted to know why I am getting this error: Notice: Undefined offset: 1 in C:\wamp\www\conf.php on line 8 from this code: <?php $link = mysql_connect("localhost","root",""); mysql_select_db("usuarios",$link); $palabra = $_GET["q"]; //$palabra = "agus#carban"; $vector = explode("#",$palabra); $consulta = "SELECT * FROM usuario WHERE nombre='".$vector[0]."' AND pass='".$vector[1]."'"; $querry = mysql_query($consulta,$link); $rdo = "No"; if(mysql_num_rows($querry)>0) { $rdo = "Si"; } echo $rdo; ?> I've done all kind of manual debugging I can't manage to solve this ! Hope I can get it working... Hello guys, this is so weird, very weird indded! PHP is generating some strange problem here over with me. Below are a short context of code that I have used to make a registration script. At the first inititial stage of code testing, everything goes well so smooth according to the plans. Then, I insert the Quote exit; function at the end of each Quote If() functions so as to curtail off completely from further execution of the script below and thereafter. Then, suddenly all the !ISSET values stop to functions. I then removed exit(); function off from my code and restore back to the last known good working stage of my code. But it seems like the ISSET function accompanied with the !(stop operator) cease to fucntion any more ever since then even though the script exhibit the same code when it was working normally good. It makes me wonder and now i'm totally frustrated, Please help!!! Now even all the operator values like ==, !=, <, > doesnt work anymore!!! P.S. I know someone would suggest me to write Quote if(!isset($_POST['Name'])) ......... in this format instead of Quote $Name but as i mentioned it earlier, i'm able to execute the script using the later one as desired in accordance to what is planned. Quote <?php $IP=$_SERVER['REMOTE_ADDR']; $Date=date('d/m/Y'); $proID=$_GET['proID']; $ref=$_GET['ref']; $Name=$_POST['Name']; $Email=$_POST['Email']; $Country=$_POST['Country']; $Username=$_POST['Username']; $Password=$_POST['Password']; $Con_Password=$_POST['Con_Password']; if(!isset($Name)) { header ('Location: reenter.php'); exit(); } if(!isset($Email)) { header ('Location: reenter.php'); exit(); } if(!isset($Country)) how do I pull out two random integers at the same time without ever possibly choosing the same integer twice? Code: [Select] if( date('j') < 1 && > 14) { $EnrollDate = "1/".date('n')."/".date('y'); }else { $EnrollDate = "15/".date('n')."/".date('y'); } What could be wrong here, i cant work! Hi,
Is there any way to use the inbuilt filter functions in PHP to filter for integer values greater than 256? All examples that I saw had a max_range of 256. Kindly suggest. Thanks.
Hi everybody, a few dasy ago i found a function which translates integers into text like this:
echo $number->written_number(101); // one hundred one
but i've got a problem, this function works fine on russian language, but that this function translate in 3 languages:
russian, english and ukrainian like this:
echo $number->written_number(101); // сто один - one hundred one - сто один
how can i add english and ukrainian languages?
When i tried to add this manually, it was okay but in one moment i received error, and all my script is broked, and now i don't know what to do, i've got a few hours to complete this test work, but unfortunately i've got no idea how to do this(
Pls help me somebody, i will infinitely grateful!!!
This is my code
<?php
require_once('languages.php');
class numberTransfer extends languages

public function written_number($i, $female = false) {
if (($i < 0) || ($i >= 1e9) || !is_int($i)) {

}
if($i == 0) {
return $this->N0. '</br>' .$this->N0eng;

else {

}
}
}
$number = new numberTransfer();
echo $number->written_number(101);
as you can see i tried to glue array with russian language words with array with english laguage words.
Probably i've got somethink like this:
$number = new numberTransfer();echo $number->written_number(101); сто один one one hundredодин one damn bullshit... Please people help me:) I almost have this right, but not quite. I am trying to echo out the average score if a person scored above 70 and my averaging isn't correct. It should echo out 89, but instead the number is 63.25. The averaging is the only part not working. Everything else works as intended. I might not have my curly braces in the proper order or something. I think it's something stupid I am forgetting. Here is my code. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Array Test</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <?php function array_average_nonzero($scores) { return array_sum($scores) / count(array_filter($scores)); } $scores["Tim"] = 98; $scores["Tom"] = 80; $scores["Mike"] = 50; $scores["Jason"] = 25; foreach( $scores as $key => $value) if($value < 70){ echo "$key scored a $value which is less than 70. <br />\n"; } elseif ($value < 70); { echo "The average score of those who scored over 70 is: " .array_sum($scores) / count($scores) . "<br />"; } ?> </body> </html> I am wondering how can I insert integers in the database without manually input it in the form. I am looking to fill the product_id and customer_id table. I would do it but only by sequence and '' quotes at the VALUE part of an INSERT statement. Also condition the insert of product_id and customer_id according to the id in the SESSION variable. Code: [Select] <?php session_start(); if (isset($_SESSION['id'])) { $userid = $_SESSION['id']; $username = $_SESSION['username']; $fname = $_POST['firstname']; $lname = $_POST['lastname']; $telephone = $_POST['telephone']; $city = $_POST['city']; $state = $_POST['state']; $itemname = $_POST['product_name']; $price = $_POST['price']; $details = $_POST['details']; $category = $_POST['category']; $subcategory = $_POST['subcategory']; $product_id = $_POST['product_id']; $customer_id = $_POST['customer_id']; $date_sold = $_POST['date_sold']; $sqlinsert = "INSERT INTO customers (id,firstname,lastname,telephone,city,state,product_name,price,details) VALUES('','$fname','$lname', '$telephone','$city','$state','$itemname','$price','$details')"; $sqlinsert2 = "INSERT INTO products (id,product_name,price,details,category,subcategory) VALUES('','$itemname','$price','$details','$category','$subcategory')"; $sqlinsert3 = "INSERT INTO sales (id,product_id, customer_id, date_sold) VALUES('','$product_id','$customer_id','$date_sold')"; $enterquery = mysql_query($sqlinsert) or die(mysql_error()); $enterquery2 = mysql_query($sqlinsert2) or die(mysql_error()); $enterquery3 = mysql_query($sqlinsert3) or die(mysql_error()); } ?> The above insert its respective fields in each table but how is it possible to INSERT it according to the SESSION['id]; so that it INSERT according to the costumer id plus that it generates and INSERT automatically in the product_id and customer_id related to the product_id and customer_id fields in products and customer table? without manually doing it. any references will be appriciated because the above code seems like the product_id and customer_id won't INSERT in relations to the customer and product table. One more thing the product_id and customer_id won't be pass from the form to this file but rather a value will be INSERT it in their field according to the id in customer and products table. Is it possible to perform type declaration which allows either an integer or a string digit (i.e. ctype-digit) instead of the following?
function someFunction(int $id){}
Looking at functions.arguments.type-declaration, I expect not. If not, would you recommend type casting before calling the function or removing type declaration from the function and performing the check manually within the function and throwing an applicable exception? Thanks Well the topic may not sound very explicit. So I'll do my best to explain it here. I have a pull down menu as part of a form, which contains the months of the year. I'm trying to store the value of this form entry using the $_POST['month'] variable into a database but first, I need to convert the month values into their corresponding integer values( that is 1 for January, 2 for February etc), in order to easily do date calculations later down the road. Any ideas about how to do this? It may be helpful to include the code for the pull down menu. Code: [Select] <p><tab> Date of Birth: <?php //Make the month pull down menu. //Array to store months. $months = array (1 => 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'); print '<select name= "month">'; foreach ($months as $key => $value) { print "\n<option value=\"$key\">$value</option>"; } print '</select>'; ?> </tab> <tab> <?php //Make the day pull down menu print '<select name= "day">'; for ($day = 1; $day <= 31; $day++) { print "\n<option value=\"$day\">$day</option>"; } print '</select>'; ?> </tab> <tab><?php //Make the year pull down menu print '<select name= "year">'; $start_year = date('Y'); for ($y = ($start_year - 18); $y >= 1900; $y--) { print "\n<option value=\"$y\">$y</option>"; } print '</select>'; ?> </tab> </p> Hi, I'm trying to retrieve the integer value between the <span> tag from a HTML source code.
HTML source code:
<span> (3861822) </span>This is the php code:
<!DOCTYPE html>
<html>
<body>
<?php
//use curl to get html content
function getHTML($url,$timeout)
{
$ch = curl_init($url); // initialize curl with given url
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]); // set useragent
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // write the response to a variable
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow redirects if any
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); // max. seconds to execute
curl_setopt($ch, CURLOPT_FAILONERROR, 1); // stop when it encounters an error
return @curl_exec($ch);
}
$html=getHTML("http://www.alibaba.com/Products",10);
preg_match("/<span>(.*)<\/span>/i", $html, $match);
$title = $match[1];
echo $title;
?>
</body>
</html>
Whenever I try to run it, this error will come out: Notice: Undefined offset: 1 in C:\xampp\htdocs\myPHP\index.php on line 19.
How to correct it so that it will display all the integer value within the tag name but without the bracket? Thanks
Edited by Raex, 20 August 2014 - 01:38 AM. is there a way I can make something like a ticket in pdf format that can have $name or the likes echo in it? if you could help get me started, that would be great! hello, here is what i have, obviosly it doesnt work. Code: [Select] $year=$_POST['y']; $yr=substr($year,-2); $mth=$_POST['m']; $init=$_POST['initial']; $jobnumber=$yr$mth2343$init; echo "$jobnumber"; P.S. thanks to everybody for their help lately! Not sure if there is a better way to do this, but I want to check whether the value in a Sticky Field is the same as what is in the Database. If what is in the Sticky Field is *exactly* what is in the Database, then the User didn't update that field, and so I would NOT do an UPDATE. Seem reasonable? Here is where I grab the value out of the Form... Code: [Select] // **************************** // Process Each Form Field. * // **************************** foreach($_POST['answerArray'] as $questionID => $response){ // Copy trimmed Form array to PHP array. $answerArray[$questionID] = trim($response); And here is where I grab the existing value in the Database... Code: [Select] // ******************** // Check for Answer. * // ******************** // Build query. $q1 = "SELECT response FROM bio_answer WHERE member_id=? AND question_id=?"; // Prepare statement. $stmt1 = mysqli_prepare($dbc, $q1); // Bind variable to query. mysqli_stmt_bind_param($stmt1, 'ii', $memberID, $questionID); // Execute query. mysqli_stmt_execute($stmt1); // Store results. mysqli_stmt_store_result($stmt1); // Check # of Records Returned. if (mysqli_stmt_num_rows($stmt1)==1){ // Answer Found. // Bind result-set to variable. mysqli_stmt_bind_result($stmt1, $currResponse); // Fetch record. mysqli_stmt_fetch($stmt1); So I guess I want to compare $answerArray[$questionID] against $currResponse and see if there are any differences?! What is the best way to do that? Any better ideas of how to check to see if the User made any changes to a field so I only do an UPDATE if there was actually a change? Thanks, Debbie Hey guys!! So basically what I am doing here is pulling the directory out of a url. URL ex: http://www.xxx.com/T...IS_WHAT_I_WANT/ Hi I am having troubles using a string in a cookie.. This doesnt work: setcookie("background", "$image_name", $expire, "/", ".gedoo.com"); Neither does this: setcookie("background", "" . $image_name . "", $expire, "/", ".gedoo.com"); If I write something before $image_name like: setcookie("background", "hello" . $image_name . "", $expire, "/", ".gedoo.com"); It will save "hello" in the cookie.. So in other words, $image_name doesnt look like it is defined.. But the funny thing is that this works on the same page: echo "File Uploaded Successfully!<br><img src='images/$image_name'>"; Anyone have any idea on what I am doing wrong? I was thinking how can I make a script that will build strings incrementing through each letter starting with "a" and ending with "zzzzzz" or what ever ending length I want such as 12. So if your were to output everything, you could find the words: "dog" "spider" "superman" "hippo" etc What would be the best way to do this, so I don't have to have a loop that is 500 blocks deep to show a word that is 500 letters example Quote a ... z aa ab ac ... az ba bb bc ... ... aaa aab aac How can i break down strings for example i have a simple search database for products where as a user searches a term this can be one, two three words and so on. I'm using a wildcard; but i want the best way to get the possible search so i would like to break down the string into separate words and then use that to search the database using wildcards is this possible? Thanks for reading. |
