Strange PHP Session Behavior

[nbaztec]

To start off, I was designing a site in PHP 5.3.5, I wrote the following code:

 

//test_login.php 
session_start(); 
.
.
if([test credentials])
  $_SESSION['user'] = '1';
else
  //Do Stuff

 

//File_2.php
if(!isset($_SESSION))
session_start(); 

echo $_SESSION['user'];
echo $_SESSION['user'];
echo $_SESSION['user'];

 

Now on my localhost(PHP 5.3.5), it correctly outputs: 111

 

But when I put the same script on my webserver (PHP 5.2.3), the same script shows output: 011

 

It's as if the reference to $_SESSION['user'] isn't made until it's referenced for the 2nd time.

 

Can anyone kindly enlighten me on this issue.

Solved. Issue with mysql_real_escape_string(). My bad.
