php - does set_error_handler catch errors that are not included into error_reporting() -

if exclude e_warning errors error_reporting() - error_reporting(e_all & ~e_warning) custom error handler registered set_error_handler('error_handler') called php warning errors?

i'm asking because there following code in kohana framework:

public static function error_handler($code, $error, $file = null, $line = null) {     if (error_reporting() & $code)     {         // error not suppressed current error reporting settings         // convert error errorexception         throw new errorexception($error, $code, 0, $file, $line);     }      // not execute php error handler     return true; } 

which checks whether triggering function should processed if (error_reporting() & $code) whereas expect function error_hanlder never triggered errors shouldn't processed.

i guess i've found answer myself (from here):

it important remember standard php error handler bypassed error types specified error_types unless callback function returns false. error_reporting() settings have no effect , error handler called regardless - still able read current value of error_reporting , act appropriately. of particular note value 0 if statement caused error prepended @ error-control operator.
