php中的键，值和数组

Question

我正在使用symfony2.3，

我想知道如何在id基础上获得rewardPoints以及这个id在0到4之间的数组位置？

喜欢 ：

我已经有了Logged User Id： -

 id = 8; 

在数组我得到了这个： -

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
    )

)

对不起我的英语不好。

谢谢。

希望这个能对您有所帮助

$counter = 0;
foreach($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
