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

)

)
