note 52255 added to function.trigger-error

I am not so familiar with this but I think you can reach some of the functionality of try..catch with this function. I would disagree or correct the previous note. The @ is not the catch, it sets the error_reporting to 0 tempolary but with set_error_handler you can try to imitate some behavior like catch. I've just made this to try if it possible, I never tried in projects but I think could work in php 4. Actually if you want to have the Trace of the error you need to use php4.3+. Maybe not many of you will create new scripts in php4 and try to have some features from php5 but in some cases (extending older projects) this could be better error handling. If this is a wrong approach, waiting for comments, if its not, use it! <? function catch($errno, $errstr, $errfile, $errline){ $GLOBALS['throw'] = $errstr; $GLOBALS['throw_info'] = array( 'Message'=>$errstr ,'Code'=>$errno ,'Line'=>$errline ,'File'=>$errfile ,'Trace'=>debug_backtrace() ); } set_error_handler('catch'); function badgirl(){ if(true){ //error occure trigger_error("BadGirlWithError",E_USER_NOTICE); // as throw with notice return; // ...because trigger_error does not stop the function }else{ return true; } } // Try $GLOBALS['throw'] = null; // ...try... $sheis = badgirl(); //could be @badgirl, display_errors is something else, this just the handling // ..try if($GLOBALS['throw']){ // This actually catch re-throws too... switch($GLOBALS['throw']){ // Catch case 'GoodGirlException': die('No bad girl today!'); break; case 'BadGirlWithError': die('Bad girl has some error'); break; default: return; // or you can make another trigger_error and re-throw another 'exception' or some other action } } echo "You will never see this line - @ only supress message, not a control flow"; echo "Wrong! You could see this:)"; ?> .mano ---- Manual Page -- http://www.php.net/manual/en/function.trigger-error.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52255 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52255&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52255&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52255&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52255&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52255&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52255&report=yes Search -- http://master.php.net/manage/user-notes.php
