note 77997 added to function.set-error-handler

Be aware of efficiency and speed of your scripts! If you use old-fashioned non-strict variable calling (example follows...), your custom error handler function degrades the script speed very big (especially for bigger projects). Because of for every "use of undefined constant" or "undefined variable" E_NOTICEs will be called your own custom error handler function. <? if ($form_variable) { ///< E_NOTICE Undefined variable // process form stuff } $foo[bar] = $const_array[baz]; ///< 2x E_NOTICE Use of undefined constant bar, baz if (!$d) { // declare default $d ///< E_NOTICE Undefined variable $d = 5; } ?> As you can see in this poor example, badly writted scripts decrease the performace very big 'cause of the error handler is called almost everytime. So use custom-error-handler on heavily used pages only if you are writing scripts strictly. (Example follows:) <? if (isset($form_variable) && $form_variable != null) { // process form stuff } $foo['bar'] = $const_array['baz']; if (!isset($d) || $d == null) { $d = 5; } ?> ---- Server IP: 212.24.129.51 Probable Submitter: 83.208.62.60 ---- Manual Page -- http://www.php.net/manual/en/function.set-error-handler.php Edit -- https://master.php.net/note/edit/77997 Del: integrated -- https://master.php.net/note/delete/77997/integrated Del: useless -- https://master.php.net/note/delete/77997/useless Del: bad code -- https://master.php.net/note/delete/77997/bad+code Del: spam -- https://master.php.net/note/delete/77997/spam Del: non-english -- https://master.php.net/note/delete/77997/non-english Del: in docs -- https://master.php.net/note/delete/77997/in+docs Del: other reasons-- https://master.php.net/note/delete/77997 Reject -- https://master.php.net/note/reject/77997 Search -- https://master.php.net/manage/user-notes.php
