php自定义二维数组排序函数array_orderby用法示例

　　本文实例讲述了php自定义二维数组排序函数array_orderby用法。分享给大家供大家参考，具体如下：

　　 <?php /** I came up with an easy way to sort database-style results. This does what example 3 does, except it takes care of creating those intermediate arrays for you before passing control on to array_multisort(). */ function array_orderby() { $args = func_get_args(); $data = array_shift($args); foreach ($args as $n => $field) { if (is_string($field)) { $tmp = array(); foreach ($data as $key => $row) $tmp[$key] = $row[$field]; $args[$n] = $tmp; } } $args[] = &$data; call_user_func_array(array_multisort, $args); return array_pop($args); } /* The sorted array is now in the return value of the function instead of being passed by reference. */ $data[] = array(volume => 67, edition => 2); $data[] = array(volume => 86, edition => 1); $data[] = array(volume => 85, edition => 6); $data[] = array(volume => 98, edition => 2); $data[] = array(volume => 86, edition => 6); $data[] = array(volume => 67, edition => 7); // Pass the array, followed by the column names and sort flags $sorted = array_orderby($data, volume, SORT_DESC, edition, SORT_ASC); print_r($sorted) ?>

　　运行结果：

　　 Array ( [0] => Array ( [volume] => 98 [edition] => 2 ) [1] => Array ( [volume] => 86 [edition] => 1 ) [2] => Array ( [volume] => 86 [edition] => 6 ) [3] => Array ( [volume] => 85 [edition] => 6 ) [4] => Array ( [volume] => 67 [edition] => 2 ) [5] => Array ( [volume] => 67 [edition] => 7 ) )
