PHP supports one error control operator: the at sign (@). When prepended to an expression in PHP, any error messages that might be generated by that expression will be ignored.
If the track_errors feature is enabled, any error message generated by the expression will be saved in the global variable $php_errormsg. This variable will be overwritten on each error, so check early if you want to use it.
<?php
/* Intentional SQL error (extra quote): */
$res = @mysql_query ("select name, code from 'namelist") or
die ("Query failed: error was '$php_errormsg'");
?>

See also error_reporting().
| Warning |
Currently the "@" error-control operator prefix will even disable error reporting for critical errors that will terminate script execution. Among other things, this means that if you use "@" to suppress errors from a certain function and either it isn't available or has been mistyped, the script will die right there with no indication as to why. |
