note 98051 added to function.set-error-handler

At work I have some code with errors that uncatched are the causes of integrity loss (people calling web services with file_get_contents that fails silently and afterwards insert garbage in the database). here is the solution I found to transform a specific set of errors into exception and afterwards be able to selectively act (with the error code) regarding categories : <? ini_set('error_reporting',E_ALL^E_NOTICE); ## first 10 bits reserved for the initial error number define('EMASK',(~0)<<10); define('ECODEMASK',~EMASK); ## categories define('IOERROR', 1<<10); define('EMPTYPARMS', 1<<11); define('FAILURE', 1<<12); ## string error patterns => code $catch_me=array( "/^(file_get_contents)\((.*)\).*failed to open stream: (.*)/ " => array ( 'mesg' => "IO::Failed to open stream with", 'code' => IOERROR | FAILURE ), "/^fopen\(.*\): Filename cannot be empty/" => array( 'msg' => "Parameters::empty", 'code' => EMPTYPARMS ) ); function error_2_exception($errno, $errstr, $errfile, $errline,$context) { global $catch_me; foreach ($catch_me as $regexp => $res) { if(preg_match($regexp,$errstr,$match)){ throw new Exception($res['mesg'],$res['code']|( $errno & EMASK ) ); } } /* switch back to PHP internal error handler */ return false; } ## => want to catch this one $f=file_get_contents("mlsdkfm"); ## dont want to break existing wrong behaviour yet (so not caught) $f=file_get_contents(''); ## magic set_error_handler("error_2_exception"); ## behaviour remains the same $f=file_get_contents(''); try { ## web services that dont work now raise an exception \o/ $f=file_get_contents("mlsdkfm"); } catch(Exception $e) { ## and I can group my exception by category echo ( $e->getCode() & FAILURE ) ?
