PHP gives one error control operator: the at sign (@).Any error messages that might be generated by
that expression will be ignored.
If you have set a custom error handler function with set_error_handler() then it will still
get called, but this custom error handler can call error_reporting() which will return 0
when the call that triggered the error was preceded by an @.
<?php/* Intentional file error */$test_file = @file ('no_existent_file') or
die ("Failed opening file: error was '$php_errormsg'");
// this works for any expression, not just functions:$val22 = @$cache[$key];// will not issue a notice if the index $key doesn't exist.
?> or add error_reporting() in the script
