Detailed explanation of timeout processing method of PHP function file_get_contents_PHP Tutorial

1. Increase the time limit of timeout
It should be noted here: set_time_limit only sets the timeout of your PHP program, not the timeout of the file_get_contents function reading the URL. To truly modify the file_get_contents delay, you can use the timeout parameter of resource $context:

Copy code The code is 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);

2. If there is a delay, there will be more Try several times
Sometimes the failure is caused by network and other factors. There is no solution, but you can modify the program. If it fails, try again several times. If it still fails, give up, because file_get_contents() will return FALSE if it fails. So you can write the code as follows:
$cnt=0;
while($cnt < 3 && ($str=@file_get_contents('http...'))===FALSE) $cnt++;
The above method is OK for dealing with timeouts.
Someone discovered 'method'=>"GET", GET can also be set to post, the function is as follows

Copy the code The code is as follows:

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

if (is_array($post)) {
ksort($post); ' content' => http_build_query($post, '', '&'),
              ); > }

$data = array (
'name' => 'test',
'email' => 'test@gmail.com',
'submit' = > 'submit',
);

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