note 81798 added to function.sizeof

For people who use this kind of idiom: for ($i=0; $i<sizeof($array); $i++) { ... } At least in PHP4, you will notice a large performance improvement if you switch to: $max = sizeof($array); for ($i=0; $i<$max; $i++) { ... } I had an array with a few thousand items in it, each of them a map with 5 key-value pairs, and just for'ing through the array took a second of CPU on a decent machine. ---- Server IP: 216.235.15.211 Probable Submitter: 206.223.175.72 ---- Manual Page -- http://www.php.net/manual/en/function.sizeof.php Edit -- https://master.php.net/note/edit/81798 Del: integrated -- https://master.php.net/note/delete/81798/integrated Del: useless -- https://master.php.net/note/delete/81798/useless Del: bad code -- https://master.php.net/note/delete/81798/bad+code Del: spam -- https://master.php.net/note/delete/81798/spam Del: non-english -- https://master.php.net/note/delete/81798/non-english Del: in docs -- https://master.php.net/note/delete/81798/in+docs Del: other reasons-- https://master.php.net/note/delete/81798 Reject -- https://master.php.net/note/reject/81798 Search -- https://master.php.net/manage/user-notes.php
