这篇文章主要介绍了php自定义二维数组排序函数array_orderby用法,结合实例形式分析了php针对二维数组进行排序的相关遍历、判定、排序等操作技巧,需要的朋友可以参考下。

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：

1. <?php
2. /**
3. 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().
4. */
5. function array_orderby()
6. {
7. $args = func_get_args();
8. $data = array_shift($args);
9. foreach ($args as $n => $field) {
10. if (is_string($field)) {
11. $tmp = array();
12. foreach ($data as $key => $row)
13. $tmp[$key] = $row[$field];
14. $args[$n] = $tmp;
15. }
16. }
17. $args[] = &$data;
18. call_user_func_array('array_multisort', $args);
19. return array_pop($args);
20. }
21. /*
22. The sorted array is now in the return value of the function instead of being passed by reference.
23. */
24. $data[] = array('volume' => 67, 'edition' => 2);
25. $data[] = array('volume' => 86, 'edition' => 1);
26. $data[] = array('volume' => 85, 'edition' => 6);
27. $data[] = array('volume' => 98, 'edition' => 2);
28. $data[] = array('volume' => 86, 'edition' => 6);
29. $data[] = array('volume' => 67, 'edition' => 7);
30. // Pass the array, followed by the column names and sort flags
31. $sorted = array_orderby($data, 'volume', SORT_DESC, 'edition', SORT_ASC);
32. print_r($sorted)
33. ?>

运行结果：

1. Array
2. (
3. [0] => Array
4. (
5. [volume] => 98
6. [edition] => 2
7. )
8. [1] => Array
9. (
10. [volume] => 86
11. [edition] => 1
12. )
13. [2] => Array
14. (
15. [volume] => 86
16. [edition] => 6
17. )
18. [3] => Array
19. (
20. [volume] => 85
21. [edition] => 6
22. )
23. [4] => Array
24. (
25. [volume] => 67
26. [edition] => 2
27. )
28. [5] => Array
29. (
30. [volume] => 67
31. [edition] => 7
32. )
33. )
