note 58565 added to function.max

In response to the previous two posters (zher0 at netcarrier dot com & walkingmantis): I was trying to do exactly what zher0 suggested; calculate the max value of a multi-dimensional array with variably sized 'sub-arrays'. Here is a simple little function I came up with to do just that: <?php function multimax( $array ) { // use foreach to iterate over our input array. foreach( $array as $value ) { // check if $value is an array... if( is_array($value) ) { // ... $value is an array so recursively pass it into multimax() to // determine it's highest value. $subvalue = multimax($value); // if the returned $subvalue is greater than our current highest value, // set it as our $return value. if( $subvalue > $return ) { $return = $subvalue; } } elseif($value > $return) { // ... $value is not an array so set the return variable if it's greater // than our highest value so far. $return = $value; } } // return (what should be) the highest value from any dimension. return $return; } ?> Please note that I have only performed very limited testing on this code -- be sure to check it thoroughly if you implement it somewhere! ---- Manual Page -- http://www.php.net/manual/en/function.max.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58565 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58565&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58565&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58565&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58565&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58565&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58565&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58565&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58565&report=yes Search -- http://master.php.net/manage/user-notes.php
