If anything failt after the @, the errormessage (or warning) will NOT be
displayed.

It's used to eliminate error messages generated by an expression.

http://www.php.net/manual/en/language.operators.errorcontrol.php

Example:

<?php
error_reporting (E_ALL);
ini_set('displa y_errors', '1');

unset($bar, $q);

$foo = $bar; // use of uninitialized variable ($bar)
$bar = @ $q; // error message suppressed
?>
