file_get_contents 速度慢的解決辦法

經過修改后有顯示加速，代碼如下：

ini_set('default_socket_timeout', 1); //關鍵點11111111111111；

$opts = array("http" => array(
"method" => "GET",
"timeout" => 60,
"Host" => "www.****.com",
"Accept" => "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
"Accept-Encoding" => "gzip, deflate, sdch",
"Accept-Language" => "zh-CN,zh;q=0.8",
"User-Agent" => "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36",
"Upgrade-Insecure-Requests" => "1",
"Connection:" => "close" //關鍵點22222222222；

 )); 
$context = stream_context_create($opts); 
$html = @file_get_contents("http://www.****.com/",false,$context);

關鍵是添加了這兩句代碼：

ini_set('default_socket_timeout', 1);

"Connection:" => "close"

雖然速度是有顯示加快了，但是偶爾還是會出現抓取不到內容的情況。

以上兩句代碼配合 curl_init()函數會是怎么樣呢？你們去試試吧。
