while working on facebook connect I have to retrieve an access token from a url ( it is not in the url itself but in the file lined to that url) so this is what I do
$url = "https://graph.facebook.com/oauth/access_token?client_id=".$facebook_app_id."&redirect_uri=http://www.example.com/facebook/oauth/&client_secret=".$facebook_secret."&code=".$code;"
function get_string_between($string, $start, $end){
$string = " ".$string;
$ini = strpos($string,$start);
if ($ini == 0) return "";
$ini += strlen($start);
$len = strpos($string,$end,$ini) - $ini;
return substr($string,$ini,$len);
}
$access_token = get_string_between(file_get_contents($url), "access_token=", "&expires=");
it looks ugly and clumsy is there a better way to do it ? thank you .
