note 104766 added to function.usort

The class method presented in the post below is by far the easiest method to use. Here's a remake which allows you to sort the array ascending or descending in a more user-friendly manner: <?php class sortByKey { var $key; function __construct($key) { $this->key = $key; } // comparison function for ascending order function asc($a,$b) { $key = $this->key; if ($a[$key] == $b[$key]) return 0; return (($a[$key] > $b[$key]) ? 1 : -1); } // comparison function for descending order function desc($a,$b) { $key = $this->key; if ($a[$key] == $b[$key]) return 0; return (($a[$key] < $b[$key]) ? 1 : -1); } } // then just call (as an example) usort($products, array(new sortByKey("price"), "desc")); // to sort an array of products by price in descending order ?> ---- Server IP: 69.147.83.197 Probable Submitter: 86.120.65.33 ---- Manual Page -- http://www.php.net/manual/en/function.usort.php Edit -- https://master.php.net/note/edit/104766 Del: integrated -- https://master.php.net/note/delete/104766/integrated Del: useless -- https://master.php.net/note/delete/104766/useless Del: bad code -- https://master.php.net/note/delete/104766/bad+code Del: spam -- https://master.php.net/note/delete/104766/spam Del: non-english -- https://master.php.net/note/delete/104766/non-english Del: in docs -- https://master.php.net/note/delete/104766/in+docs Del: other reasons-- https://master.php.net/note/delete/104766 Reject -- https://master.php.net/note/reject/104766 Search -- https://master.php.net/manage/user-notes.php
