file_get_contents()是否具有超时设置? [英] Does file_get_contents() have a timeout setting?

问题描述

我正在循环中使用 file_get_contents() 方法调用一系列链接.每个链接可能需要15分钟以上的时间来处理.现在，我担心PHP的file_get_contents()是否有超时期限?

I am calling a series of links using the file_get_contents() method in a loop. Each link may take more than 15 minutes to process. Now, I worry about whether PHP's file_get_contents() has a timeout period?

如果是，它将因通话超时而移至下一个链接.我不想在未完成前一个链接的情况下调用下一个链接.

If yes, it will time out with a call and move to next link. I don't want to call the next link without the prior one finishing.

所以，请告诉我file_get_contents()是否有超时期限.包含file_get_contents()的文件被设置为 set_time_limit() 为零(无限制).

So, please tell me whether file_get_contents() has a timeout period. The file which contains the file_get_contents() is set to set_time_limit() to zero (unlimited).

推荐答案

默认超时由 default_socket_timeout初始设置，即60秒.您也可以随时更改它:

The default timeout is defined by default_socket_timeout ini-setting, which is 60 seconds. You can also change it on the fly:

ini_set('default_socket_timeout', 900); // 900 Seconds = 15 Minutes

设置超时的另一种方法是使用 stream_context_create 进行设置超时为 HTTP上下文选项. http"rel =" noreferrer> HTTP流包装器正在使用:

Another way to set a timeout, would be to use stream_context_create to set the timeout as HTTP context options of the HTTP stream wrapper in use:

$ctx = stream_context_create(array('http'=>
    array(
        'timeout' => 1200,  //1200 Seconds is 20 Minutes
    )
));

echo file_get_contents('http://example.com/', false, $ctx);
