note 23915 added to function.asort

This does everything the above casort does, with the benefit of not resetting keys. ( The above casort dies on weird indexes such as $x['a'], and it requires you to have everything numbered from [0]..[n] ) It also allows you to plug in your own comparison function. I've fallen in love with uasort and uksort, they are the bomb. You can sort ANYTHING with them. :) The only difference between 'aosort' and the built-in sort functions is the sorted array is returned, rather than sorted in place, this is b/c php only supports pass by value, there is no pass by reference (yet?). THE CODE: <pre><? // aosort - object sort // by default this sorts case insensitively on strings // use the comparison function to sort according to your needs. function aosort($x,$var,$cmp='strcasecmp'){ uasort($x, create_function('$a,$b', 'return '.$cmp.'( $a->'.$var.',$b->'.$var.');') ); return $x; } // Feature Test function myLess($y,$z) { if ($y) return $y < $z; else return 0; }; class Bob{ var $x; var $y; function Bob($x,$y){$this->x=$x;$this->y=$y;} function getX(){return $this->x;} function getY(){return $this->y;} } $it[2] = new Bob(2,'az'); $it[4] = new Bob(3,'Ad'); $it[6] = new Bob(1,'ab'); print_r($it); $it = aosort($it,'getY()'); print_r($it); $it = aosort($it,'getX()','myLess'); print_r($it); ?></pre> -- http://www.php.net/manual/en/function.asort.php http://master.php.net/manage/user-notes.php?action=edit+23915 http://master.php.net/manage/user-notes.php?action=delete+23915 http://master.php.net/manage/user-notes.php?action=reject+23915
