排序多維數組的字母順序，按價值計算，其存儲在一個新的變量

Question

，我有以下陣列我想價值，A到Z，並存儲在一個新 arary $atoz_people排序：

$people = (
[0] => Array 
    (
     [id] => 1 
     [name] => Ken 
    ) 

[1] => Array 
    (
     [id] => 2 
     [name] => Anne 
    ) 

[2] => Array 
    (
     [id] => 3 
     [name] => Bob 
    ) 

); 

我用 「經典」 asort($people)：

$atoz_people = $people; 
asort($atoz_people); 
print_r($atoz_people); 

它不工作，很遺憾。爲了得到下面的數組，我應該改變什麼？它甚至有可能嗎？

$atoz_people = (
    [1] => Array 
    (
     [id] => 2 
     [name] => Anne 
    ) 
    [2] => Array 
    (
     [id] => 3 
     [name] => Bob 
    ) 
    [0] => Array 
    (
     [id] => 1 
     [name] => Ken 
    )  

); 

Answer 1

對於多維您可以使用方法如usort或uasort

uasort($people,"sort_name"); 
var_dump($people); 
function sort_name($a,$b) 
{ 
    return $a["name"] > $b["name"]; 
}

Answer 2

1）存儲inital陣列中的一個新的變量：

$atoz_people = $people; 

2）創建排序功能：

function sort_by_name($a,$b) 
{ 
    return $a["name"] > $b["name"]; 
} 

3）分類陣列

uasort($atoz_people,"sort_by_name"); 
print_r_html($atoz_people);
