PHP函數array_multisort()實現多維陣列排序的樣本講解_PHP教程

對於Listing J樣本為我們具體說明了PHP函數array_multisort()的工作方式：

php 
$data = array(array("id" => 1, "name" => "Boney M", "rating" => 3),  
array("id" => 2, "name" => "Take That", "rating" => 1),  
array("id" => 3, "name" => "The Killers", "rating" => 4),  
array("id" => 4, "name" => "Lusain", "rating" => 3),  
); foreach ($data as $key => $value) {  
$name[$key] = $value['name'];  
$rating[$key] = $value['rating'];  
}  
array_multisort($rating, $name, $data); print_r($data);
?> 

這裡，我們在$data數組中類比了一個行和列數組。然後，我使用PHP函數array_multisort()對資料集合進行重排，首先是根據rating進行排序，然後，如果rating相等的話，再根據name排序。它的輸出結果如下：

Array ([0] => Array

(

[id] => 2

[name] => Take That

[rating] => 1

) [1] => Array

(

[id] => 1

[name] => Boney M

[rating] => 3

)

[2] => Array

(

[id] => 4

[name] => Lusain

[rating] => 3

)

[3] => Array

(

[id] => 3

[name] => The Killers

[rating] => 4

)

)

PHP函數array_multisort()是PHP中最有用的函數之一，它有非常廣泛的應用範圍。另外，就如你在例子中所看到的，它能對多個不相關的數組進行排序，也可以使用其中的一個元素作為下次排序的基礎，還可以對資料庫結果集進行排序。
