我正在使用这个 php 代码来解析这个 xml 结果以获得subscriberCount:62

<?php
$det = simplexml_load_file('http://gdata.youtube.com/feeds/api/users/worshipuk');

echo "<pre>";
print_r($det);
?>

如何使用 php 通过这个 api 获取subscriberCount？

【问题讨论】：

问题在哪里，问题出在哪里？

@AwaisQarni 如何使用 php 使用此 api 获取subscriberCount ？

请输入print_r($det);的结果

【参考方案1】：

我也有同样的问题。使用下面的代码我相信你会得到你的subscriberCount。

$name = '崇拜';
$url = 'http://gdata.youtube.com/feeds/api/users/'。 urlencode($name).'?alt=json';
$json = @file_get_contents($url); // 调皮的@-operator，使用正确的错误处理
$data = json_decode($json, TRUE);
$count = (int) $data['entry']['yt$statistics']['subscriberCount'];

回声$计数；

【参考方案2】：

你也可以使用这个功能：

function get_yt_subs($username)  

$xmlData = file_get_contents('http://gdata.youtube.com/feeds/api/users/' . strtolower($username)); 
$xmlData = str_replace('yt:', 'yt', $xmlData); 

$xml = new SimpleXMLElement($xmlData); 

$subs = $xml->ytstatistics['subscriberCount']; 

return($subs); 

使用示例：

PHP 代码： get_yt_subs('GameTuts') 返回：
