note 64023 added to function.set-error-handler

if you wan't to know the current error-handler set use something like this: $current_errorhandler = set_error_handler("myerrorhandler"); restore_error_handler(); this will set your custom error_handler and return the name of the previous set error handler. by calling restore_error_handler, you remove your custom error_handler and set the error_handler that was set back again. this way you can also switch back to php-default error-handler without knowing how many error-handler already are set, by using a loop till an empty string is returned. because an empty string means "no error-handler set" wich means php's default errorhandler is set back. like in this code below: function restore_phperrorhandler() { // get current error handler. $previous_errorhandler = set_error_handler("myerrorhandler"); restore_error_handler(); $max_loops = 20; $cur_loops = 0; // if current error handler is not already php's or fails. if(($previous_errorhandler != NULL) OR ($previous_errorhandler != "")){ while($previous_errorhandler != ""){ $cur_loops = $cur_loops + 1; // check if not exceeding infinit loop. if($cur_loops >= $max_loops){ trigger_error("Restoring exceeds max. loops.", E_USER_WARNING); return false; } //switch to previous handler. restore_error_handler(); // get its name and switch to it again. $previous_errorhandler = set_error_handler("myerrorhandler"); restore_error_handler(); // check if getting errorhandler failed. if($previous_errorhandler == NULL){ trigger_error("Failed to get prev. error handler", E_USER_WARNING); return false; // empty string = php-default error handler }elseif($previous_errorhandler == ""){ return true; } } }else{ trigger_error("Current Error-Handler is default.", E_USER_NOTICE); return true; } } this function will loop and return true when no error handler is left. leaving php-default handler in controll again. this is usefull if you want to disable your own error-handler but be sure that php's is handling your error's and not any other error-handler. ---- Server IP: 66.163.161.117 Probable Submitter: 82.75.98.252 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.set-error-handler.php Edit -- http://master.php.net/note/edit/64023 Del: integrated -- http://master.php.net/note/delete/64023/integrated Del: useless -- http://master.php.net/note/delete/64023/useless Del: bad code -- http://master.php.net/note/delete/64023/bad+code Del: spam -- http://master.php.net/note/delete/64023/spam Del: non-english -- http://master.php.net/note/delete/64023/non-english Del: in docs -- http://master.php.net/note/delete/64023/in+docs Del: other reasons-- http://master.php.net/note/delete/64023 Reject -- http://master.php.net/note/reject/64023 Search -- http://master.php.net/manage/user-notes.php
