The @ operator suppresses error messages.

A usual example is: 
<?php
$v = @$a['non-existing-key'];
?>

which suppresses the "undefined index" PHP notice.

Another example is: 
<?php
@include('non_existent_file');
?>


In this case, @ not only suppresses error messages for non-existing file, it also suppresses any error messages coming from the included file when it does exist.
  1. Create file test.php: 
    <?php
@include('test.inc');
?>

  2. Create test.inc: 
    <?php
<?php
    garbage
?>

  3. The "undefined constant" PHP notice message is suppressed by @.
