Deep into PHP function file_get_contents Timeout processing method _php instance

I. Increase time limit for timeouts
Note here: Set_time_limit only sets the timeout for your PHP program, not the timeout for the file_get_contents function to read the URL. The real modification of the file_get_contents delay can be resource $context timeout parameters:

Copy Code code as follows:

$opts = Array (
' HTTP ' =>array (
' Method ' => ' get ',
' Timeout ' =>60,
)  );
$context = Stream_context_create ($opts); $html =file_get_contents (' http://www.example.com ', false, $context);

if 二、一次 has a delay, try it a few more times.
Sometimes failure is due to the network and other factors, there is no solution, but can modify the program, failed to retry several times, still fail to give up, because file_get_contents () if the failure will return FALSE, so you can write the following code:
$cnt = 0;
while ($cnt < 3 && ($str = @file_get_contents (' http ... ')) ===false $cnt + +;
The above method of dealing with timeout is OK.
Someone has found the ' method ' => ' get ', which can also be set to post, as follows

Copy Code code as follows:

function Post ($url, $post = null)
{
$context = Array ();

if (Is_array ($post)) {
Ksort ($post);

$context [' http '] = Array (
' Timeout ' =>60,
' Method ' => ' POST ',
' Content ' => http_build_query ($post, ', ' & '),
);
}

Return file_get_contents ($url, False, Stream_context_create ($context));
}

$data = Array (
' Name ' => ' test ',
' Email ' => ' test@gmail.com ',
' Submit ' => ' Submit ',
);

echo Post (' http://www.example.com ', $data);
