按键值在数组中进行多维搜索[PHP]

问题描述：

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);
}

我试图在数组中使用itag值找到url值。我想找到url值in 具有itag值18（itag = 18）的数组。 p>

 ＆lt;？php 
 $ videoId =  “EJOnwF8mgXc”;

 $ videoId），$ info）; 
 $ streams = $ info ['url_encoded_fmt_stream_map']; 
 $  streams = explode（'，'，$ streams）; 
foreach（$ streams as $ stream）{
parse_str（$ stream，$ data）; 
print_r（$ data）; 
}

答

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'];
    }
}
