note 115887 added to function.method-exists

I was wondering if caching the the methods in an array would have a faster lookup. So I ran a very simple benchmark using xdebug_time_index() with 10000 iterations on each statement. using PHP 5.3.13 btw <?php // using an actual instance of an object shows 0.10398316383362 secs method_exist($object, $method); ?> <?php // using a string shows 0.12779307365417 secs method_exist('ClassName', $method); ?> <?php $array = array(/*method names with numeric index*/); // shows 0.10288906097412 secs in_array($method, $array); ?> <?php $assoc = array( /*method name as key and value*/ ); // shows 0.017536878585815 secs isset( $assoc[$method] ); ?> From the looks of the results, there is very little difference in method_exist and in_array. Isset seems to the fastest and using a string as the first parameter is the slowest. Please note that the test was done on multiple methods, not just one, the code presented above is to show the results, not the actual test code that ran. Also, this was tested just out of curiosity and I didn't set up a specific environment or used any profiling tools, and it was not meant to be an official benchmark in anyway. ---- Server IP: 72.52.91.14 Probable Submitter: 108.181.200.19 ---- Manual Page -- http://php.net/manual/en/function.method-exists.php Edit -- https://master.php.net/note/edit/115887 Del: integrated -- https://master.php.net/note/delete/115887/integrated Del: useless -- https://master.php.net/note/delete/115887/useless Del: bad code -- https://master.php.net/note/delete/115887/bad+code Del: spam -- https://master.php.net/note/delete/115887/spam Del: non-english -- https://master.php.net/note/delete/115887/non-english Del: in docs -- https://master.php.net/note/delete/115887/in+docs Del: other reasons-- https://master.php.net/note/delete/115887 Reject -- https://master.php.net/note/reject/115887 Search -- https://master.php.net/manage/user-notes.php
