To sumeruter+php add an at gmail dot com: This is not functional for all arrays - not always is returned the highest value. For example: <?php $array = Array ( "first" => Array( 0 => 19, 1 => 41, 2 => 7, 3 => 21, 4 => 32, ), "second" => Array ( 0 => 8, 1 => 84, 2 => 63, 3 => 61, 4 => 100, )); ECHO max(max($array)); // = 41 ?> It will return 41 instead of expected 100. It's because the array is compared from left to right, as is written in manual: $array["first"][0] > $array["second"][0] ? RETURN $array["first"][0] : RETURN $array["second"][0] Which sub-array is returned depends only on the first values of them. ---- Server IP: 212.24.129.51 Probable Submitter: 213.155.231.66 ---- Manual Page -- http://www.php.net/manual/en/function.max.php Edit -- https://master.php.net/note/edit/88475 Del: integrated -- https://master.php.net/note/delete/88475/integrated Del: useless -- https://master.php.net/note/delete/88475/useless Del: bad code -- https://master.php.net/note/delete/88475/bad+code Del: spam -- https://master.php.net/note/delete/88475/spam Del: non-english -- https://master.php.net/note/delete/88475/non-english Del: in docs -- https://master.php.net/note/delete/88475/in+docs Del: other reasons-- https://master.php.net/note/delete/88475 Reject -- https://master.php.net/note/reject/88475 Search -- https://master.php.net/manage/user-notes.php
