外部资源的file_get_contents（）可能会出去吗？

Question

Hello i would like to know if i use file_get_contents() for external resource but the server where's the file doesn't work or is too late what appen....

Example i tried:

<?php
$string = file_get_contents('https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/1.0_week_age.kml');
print_r($string);

//file of external resource is kml

?>

works for how long ? And if going "out time" $string will be empty ?

Thanks a lot and sorry for my english :)

You can set your own timeout using this:

ini_set('default_socket_timeout', 300); // 5 minutes
