php - 在多维数组中搜索

Question

这是一个多维数组：

[0] => Array (   
    [order_total_id] => 8160  
    [order_id] => 2048 [code] => sub_total  
    [title] => Medzi-súčet  
    [text] => 5,75€  
    [value] => 5.7500  
    [sort_order] => 1 )   
[1] => Array (   
    [order_total_id] => 8161  
    [order_id] => 2048  
    [code] => shipping  
    [title] => Doporučený list  
    [text] => 2,00€  
    [value] => 2.0000  
    [sort_order] => 3 )  
[2] => Array (  
    [order_total_id] => 8162  
    [order_id] => 2048  
    [code] => tax  
    [title] => DPH 20%  
    [text] => 1,15€  
    [value] => 1.1500  
    [sort_order] => 5 )  
[3] => Array (  
    [order_total_id] => 8163  
    [order_id] => 2048  
    [code] => total  
    [title] => Celkom  
    [text] => 8,90€  
    [value] => 8.9000  
    [sort_order] => 6 )  

我的问题是：有可能得到[value] => 8.9000（[value]可以在 md 数组中多次）？我认为正确的方法是首先找到[code] => total以识别正确的数组，然后在同一个数组中找到 [total] 键。为什么？因为[code] => total可以在子数组 [0], [1], [2], [3] 中有时只有 [0],[1] 子数组。

如果那行得通，最好找到[code] => shipping并[value] => 2.0000

感谢你们。

<?php    

function myMulti_Array_Search($theNeedle, $theHaystack, $keyToSearch) 
        { 
        foreach($theHaystack as $theKey => $theValue) 
            { 
            $intCurrentKey = $theKey;    

            if($theValue[$keyToSearch] == $theNeedle) 
                { 

                return $intCurrentKey ; 
                } 
            else 
                { 
                return 0; 
                } 
            } 
        } 

?>
