Question

My web server is acting wierd. It seems like it executes scripts (PHP) twice before sending then to apache.

I’ve run this file:

<?php
echo '<pre>';
session_start();
$_SESSION['index']++;
echo '<br>';
print_r($_SESSION);
?>

And I know that ++ will give a notice at first, but it’s just to investigate if it runs twice. Anyway, the printed session shows that the index-index increases by two each time you load the page.

The webserver is apache2, php5 installed on a debian unit.

Anyone has any ideas?

Answer 1

echo '<pre>'; //Headers and cookies already sent.
session_start(); //Cannot set cookie anymore, system tries again, I guess

Start session first, then output anything.
Try placing session_start(); on top
