Use @ to suppress errors

In PHP, you can use the @ operator to suppress individual errors. For example, if you don't want PHP to report that it doesn't include a certain file, you can write code like this:

@include ('config.inc.php');

Or if you don't want to see the "divide by 0" error:

$x = 8;
$y = 0;
$num = @($x/$y);

Like a function call Like mathematical operations, the @ symbol can only handle expressions. The @ symbol cannot be used before conditional statements, loop statements, function definitions, etc.

As a rule of thumb, I recommend using the @ symbol for functions whose failure will not affect the overall functionality of the script. Alternatively, you can suppress errors when you can handle PHP's errors more gracefully yourself.

Some open source software uses part of the code to suppress errors:

//code from phpbb3(common.php)  
// If we are on PHP >= 6.0.0 we do not need some code  
if (version_compare(PHP_VERSION, '6.0.0-dev', '>='))  
{  
 /** 
 * @ignore 
 */  
 define('STRIP', false);  
}  
else  
{  
 @set_magic_quotes_runtime(0);  
  
 // Be paranoid with passed vars  
 if (@ini_get('register_globals') == '1' || strtolower(@ini_get('register_globals')) == 'on' || !function_exists('ini_get'))  
 {  
  deregister_globals();  
 }  
  
 define('STRIP', (get_magic_quotes_gpc()) ? true : false);  
}  
  
//code from phpbb3(style.php)  
$dir = @opendir("{$phpbb_root_path}styles/{$theme['theme_path']}/theme");  
  
//code from phpbb3(adm/index.php)  
                    if (file_exists($phpbb_root_path . $cfg_array[$config_name]) && !@is_writable($phpbb_root_path . $cfg_array[$config_name]))  
                    {  
                        $error[] = sprintf($user->lang['DIRECTORY_NOT_WRITABLE'], $cfg_array[$config_name]);  
                    }  
  
//code from phpbb3(functions.php)  
    if (($fh = @fopen('/dev/urandom', 'rb')))  
    {  
        $random = fread($fh, $count);  
        fclose($fh);  
    }
