time - If function execute more than x seconds php -

in script use function:

function url_exists($url) {  if ((strpos($url, "http")) === false) $url = "http://" . $url;  if (is_array(@get_headers($url)))       return true;  else       return false; } 

how can set time limit of execute function @get_headers? need function set_time_limit() works 1 function, not whole script.

the function get_headers() doesn't supports timeout or context param. try:

ini_set('default_socket_timeout', your_value_in_seconds); 

this set default timeout value of choice. don't forget reset timeout after operation has finished.
