I am new to PHP regex, and I read the http://php.net/manual/en/function.preg-match.php. but can't find the way to fix my bug. Could you please give me a hand? Thanks.

<?php

$myURL = "/something/";  
// If myURL include two or more than two '/' then return Found, Else return Not found two '/'

if (preg_match("/\/?\//", $myURL)) {
    echo "found";
} else {
    echo "not found";
}
?>

I suggest using substr_count.

$numSlashes = substr_count($text, '/');

Shai.

<?php

$myURL = "/something/";  
// If myURL include two or more than two '/' then return Found, Else return Not found two '/'

if (preg_match("/\/.*\//", $myURL)) {
    echo "found";
} else {
    echo "not found";
}
?>

If you want to go by regex way then:

$myURL = "/some//thing/";  


if (array_search("//", preg_match_all("/\/?\//", $myURL))) {
    echo "found";
} else {
    echo "not found";
}
?>
