按键值在数组中进行多维搜索[PHP]

Question

I am trying to find the url value using itag value in the array. I want to find the url value in the array with the itag value 18 (itag=18).

PHP Code:

<?php
$videoId = "EJOnwF8mgXc";
parse_str(file_get_contents("http://youtube.com/get_video_info?video_id=" . 
$videoId), $info);
$streams = $info['url_encoded_fmt_stream_map'];
$streams = explode(',', $streams);
foreach ($streams as $stream) {
parse_str($stream, $data);
print_r($data);
}

A simple "if" statement will do :

<?php
$videoId = "EJOnwF8mgXc";
parse_str(file_get_contents("http://youtube.com/get_video_info?video_id=" . 
$videoId), $info);
$streams = $info['url_encoded_fmt_stream_map'];
$streams = explode(',', $streams);
foreach ($streams as $stream) {
    parse_str($stream, $data);
    if($data['itag'] == 18){
        echo $data['url'];
    }
}
