Another possible solution could be:
$ary = explode('://', $url);
if (1 >= count($ary)) {
echo 'No schema specified!';
} else {
// Schema specified.
// $ary[0] is the protocol
$allowed = array('http', 'https');
if (FALSE == in_array($ary[0], $allowed) {
// Protocol not valid!
exit(1); // or return FALSE; whatever...
}
// $ary[1] is the uri, validate with filter_var().
}
Hope this helps.
