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
 )
)
