At times the get_file_contents takes too long and that hangs the entire script. Is there any way of setting a time out limit on get_file_contents, without modifying the maximum execution time of the script?

有时get_file_contents需要太长时间并挂起整个脚本。有没有办法在get_file_contents上设置超时限制,而不修改脚本的最大执行时间?

Edit:

Its taking long because the file does not exist. I am getting "failed to open stream: HTTP request failed!" error. But it takes forever.

它花了很长时间,因为文件不存在。我收到“无法打开流:HTTP请求失败!”错误。但它需要永远。

Seems to be possible in PHP > 5.2.1 by creating a context with the timeout option.

通过使用timeout选项创建上下文,似乎可以在PHP> 5.2.1中实现。

Slightly amended example from the manual page:

手册页中略有修改的示例:

<?php

$opts = array('http' =>
    array(
        'method'  => 'GET',
        'timeout' => 120 
    )
);

$context  = stream_context_create($opts);

$result = file_get_contents('http://example.com/get.php', false, $context);

?>

you count use ini_set and set "default_socket_timeout" before using file_get_contents and then restore the old value after it - if would affect some other parts of your code...

你计算使用ini_set并在使用file_get_contents之前设置“default_socket_timeout”然后恢复它之后的旧值 - 如果会影响你代码的其他部分......
