note 93145 added to function.get-class

For those of you who are wondering whether it is faster to use get_class or instanceof, I wrote the following piece of code to test it: <?php $TestObject = new TestingObject; $InstanceOfTimeBefore = microtime(true); for($Counter = 0; $Counter < 10000000; $Counter++) $Result = $TestObject instanceof TestingObject; $InstanceOfTimeAfter = microtime(true); $GetClassTimeBefore = microtime(true); for($Counter = 0; $Counter < 10000000; $Counter++) $Result = get_class($TestObject); $GetClassTimeAfter = microtime(true); echo "Time for instanceof: " . number_format($InstanceOfTimeAfter - $InstanceOfTimeBefore, 3) . "\n"; echo "Time for get_class: " . number_format($GetClassTimeAfter - $GetClassTimeBefore, 3) . "\n"; ?> The results on my server: Time for instanceof: 5.585 Time for get_class: 7.788 So instanceof is a bit faster. Keep in mind that I had to check 10 million times in order to get a difference of that magnitude. My conclusion is that it probably does not matter which one you use since both ways are extremely fast. ---- Server IP: 66.207.199.35 Probable Submitter: 64.235.206.57 ---- Manual Page -- http://www.php.net/manual/en/function.get-class.php Edit -- https://master.php.net/note/edit/93145 Del: integrated -- https://master.php.net/note/delete/93145/integrated Del: useless -- https://master.php.net/note/delete/93145/useless Del: bad code -- https://master.php.net/note/delete/93145/bad+code Del: spam -- https://master.php.net/note/delete/93145/spam Del: non-english -- https://master.php.net/note/delete/93145/non-english Del: in docs -- https://master.php.net/note/delete/93145/in+docs Del: other reasons-- https://master.php.net/note/delete/93145 Reject -- https://master.php.net/note/reject/93145 Search -- https://master.php.net/manage/user-notes.php
