【问题描述】:
所以我有这个私有函数:
private function curl_get($url)
{
// Initiate the curl session
$ch = curl_init();
// Set the URL
curl_setopt($ch, CURLOPT_URL, $url);
// Removes the headers from the output
curl_setopt($ch, CURLOPT_HEADER, 0);
// Return the output instead of displaying it directly
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
@curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
// Execute the curl session
$output = curl_exec($ch);
// Close the curl session
curl_close($ch);
return $output;
}
我使用 if 例如这个链接:http://www.metacafe.com/api/item/cb-xuFyGC0jJqPfhMoFnewj4Da_ZhHCz4L2/
现在的问题是它没有返回所有数据,我得到的只是:

为什么它不返回对我来说非常重要的描述和标签?
