With this piece of code the session variable is not keeping track of the increment:

<?php
error_reporting(63);
session_start();
$abc = '';
session_register('abc');

$abc += 1;
$_SESSION['abc'] += 2;
print "<pre>$abc\n\n";
print_r( $_SESSION);
?>

While minor alteration of above code as below the session variable works:

<?php
error_reporting(63);
$abc = '';
session_start();
session_register('abc');

$abc += 1;
$_SESSION['abc'] += 2;
print "<pre>$abc\n\n";
print_r( $_SESSION);
?>

so what do you expect to happen when you overwrite
the value of a session variable immediately after
restoring it using session_start()?


PS:
> error_reporting(63);

*never* use numeric constants for error reporting settings, *always* use the symbolic constants like E_ALL and E_WARNING, unless you want to get bitten by future additions of error classes
