键，值和数组在PHP

Question

我使用symfony2.3，

我想知道我怎样才能得到ID基地rewardPoints和位置0之间 阵列这个ID抱到4？

像：

我已经得到了登录用户名： -

id = 8; 

在阵列我得到这个： -

Array 
(
[0] => Array 
    (
     [rewardPoints] => 790 
     [id] => 1 
    ) 

[1] => Array 
    (
     [rewardPoints] => 35 
     [id] => 8 
    ) 

[2] => Array 
    (
     [rewardPoints] => 25 
     [id] => 14 
    ) 

[3] => Array 
    (
     [rewardPoints] => 10 
     [id] => 15 
    ) 

[4] => Array 
    (
     [rewardPoints] => 5 
     [id] => 16 
    ) 

) 

对不起，我的英语水平。

谢谢。

希望这将帮助你

$counter = 0; 
foreach($yourArray as $subArray){ 
    if($subArray['id'] == 8){   // here set the id what you need 
     $position = $counter; 
     $revertPoint = $subArray['rewardPoints']; //here you set the rewardPoints into variable 
     } 
     $counter++; 
} 

echo $revertPoint;//result 
echo $position; // position in main array
