這篇文章主要介紹了php自定義二維數組排序函數array_orderby用法,結合實例形式分析了php針對二維數組進行排序的相關遍歷、判定、排序等操作技巧,需要的朋友可以參考下
本文實例講述了php自定義二維數組排序函數array_orderby用法。分享給大家供大家參考，具體如下：<?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)
?>
運行結果：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
)
)
