File_get_contents is particularly slow in downloading a 20 k image resource. How can this problem be solved?

{Code ...}

$url = 'http://wx.qlogo.cn/mmopen/xu0fLo9waqKSTDO7j0kSO41O5Luq3LB6ozUvY4O7OsXUWNicB49fBs8nGYzoqcwGDARQZHpVuic4JSDngEVjVo10BoiaPd0iciaOb/0';$content = file_get_contents($url);file_put_contents('uploads/a.jpg', $content);

$urlAdd above this lineini_set('default_socket_timeout', 1);Set the default timeout value.

The image you requested, supported by the recipient's serverConnection: keep-aliveTherefore, after receiving data, PHP maintains a period of time and waits until the time-out period is reached. Therefore, it is slow when the default time-out period is set.

You can use the same code (without ini_set) to obtain the URLhttp://sfault-avatar.b0.upaiyun.com/160/666/1606661144-55fe2a534b79f_huge256The other party told PHP that the connection can be closed after receiving the output data.

function curl_file_get_contents($durl){   $ch = curl_init();   curl_setopt($ch, CURLOPT_URL, $durl);   curl_setopt($ch, CURLOPT_TIMEOUT, 2);   curl_setopt($ch, CURLOPT_USERAGENT, _USERAGENT_);   curl_setopt($ch, CURLOPT_REFERER,_REFERER_);   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);   $r = curl_exec($ch);   curl_close($ch);   return $r; }$url = 'http://wx.qlogo.cn/mmopen/xu0fLo9waqKSTDO7j0kSO41O5Luq3LB6ozUvY4O7OsXUWNicB49fBs8nGYzoqcwGDARQZHpVuic4JSDngEVjVo10BoiaPd0iciaOb/0';$a = curl_file_get_contents($url);file_put_contents('uploads/2.jpg', $a);

This will soon ....

This should be the reason for the network. Just download an image and there is no difference in any method.
