Execution Error very odd!!!

[jonsof]

I have the following script

delete_user.php

<?php

 mysql_connect("localhost");
 mysql_select_db("authentication");

$username=$_POST[users];

if($_POST[delete]) {
echo $username;

if($username) {

mysql_query("DELETE FROM users WHERE username='$username'");
echo "<center> Successfully Deleted $username</center>";
empty($username);
echo "<meta http-equiv='refresh' content='3;url=delete_user.html'>";}

else {echo "<center>Nobody was inserted for deletion</center>";}
}
mysql_close(); ?>

When i parser executes the above script is shows that there is a problem such as "Execution Error"

Where is the problem?

I have to note that the $_POST[xxx] variable cames from another script and in particular a form called delete_user.html

Well all errors including Parse.. Help you find what is wrong... I didnt look through your code much.. But tell us the line show us a couple a lines around it.. Sometimes its not that line thats the trouble

Exactly. The parser doesn't tells us where the error is but says that there is a parser error execution. No line but general!

if($_POST[delete]) {

The parser is all confused because "delete" is the name of a built in php function. You should quote word "delete" since you are using it as a string.

But really you should make it a habit to not use common words as variable names, database columns, form field names, etc. There's too much risk of what are called collisions.
