note 100132 added to function.count

Adding on to what yarolan down there said, one can do this to avoid calculating the length of an array on each cycle of a for loop: <?php for ($i = 0, $arr_length = count($array); $i <= $arr_length; $i++) ?> This will assign the value of count($array) to the variable $arr_length when it gives the value of 0 to $i, so it will only have to run count() that one time at the beginning of the loop. ---- Server IP: 69.147.83.197 Probable Submitter: 168.213.1.132 ---- Manual Page -- http://www.php.net/manual/en/function.count.php Edit -- https://master.php.net/note/edit/100132 Del: integrated -- https://master.php.net/note/delete/100132/integrated Del: useless -- https://master.php.net/note/delete/100132/useless Del: bad code -- https://master.php.net/note/delete/100132/bad+code Del: spam -- https://master.php.net/note/delete/100132/spam Del: non-english -- https://master.php.net/note/delete/100132/non-english Del: in docs -- https://master.php.net/note/delete/100132/in+docs Del: other reasons-- https://master.php.net/note/delete/100132 Reject -- https://master.php.net/note/reject/100132 Search -- https://master.php.net/manage/user-notes.php
