note 114489 added to function.count

If you want to check whether large arrays contain a specific (less) number of array elements, don't use count(). This is very slow because each element has to get iterated. This is much faster: function isArrayCount(array $array, $count) { $count = (int) $count; $result = reset($array); if ($count === 0) { // for empty arrays reset returns FALSE // we have to switch the boolean result $result = !$result; } for($i = 1; $i < $count; $i++) { if (next($array) === FALSE) { $result = FALSE; break; } } return $result; } ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/function.count.php Edit -- https://master.php.net/note/edit/114489 Del: integrated -- https://master.php.net/note/delete/114489/integrated Del: useless -- https://master.php.net/note/delete/114489/useless Del: bad code -- https://master.php.net/note/delete/114489/bad+code Del: spam -- https://master.php.net/note/delete/114489/spam Del: non-english -- https://master.php.net/note/delete/114489/non-english Del: in docs -- https://master.php.net/note/delete/114489/in+docs Del: other reasons-- https://master.php.net/note/delete/114489 Reject -- https://master.php.net/note/reject/114489 Search -- https://master.php.net/manage/user-notes.php
