Question

This script should detect the last portion in the full path, and if it is stackoverflow output ok

$current_url = $_SERVER['REQUEST_URI'];

$current_url_arr = explode('/',$current_url);
$count = count($current_url_arr);

if($current_url_arr[$count-2] == 'stackoverflow'){
    echo 'ok';
}
else {
    echo 'not ok';
}

Example 1: www.myserver.ext/something/else/stackoverflow/
Output: ok

---

Example 2: www.myserver.ext/something/else/stackoverflow
Output: not ok

---

Example 3: www.myserver.ext/something/else/stackoverflow/foo
Output: not ok

I hope that you understand the idea. This script works fine, but I’m wondering if there is any better, elegant way to read last portion of URL?

Answer 1

Yes! There’s $_SERVER['PATH_INFO']:

if(isset($_SERVER['PATH_INFO'])) {
    $info = explode('/', trim($_SERVER['PATH_INFO'], '/'));

    if($info[count($info) - 1] === 'stackoverflow') {
        echo 'ok';
    } else {
        echo 'not ok';
    }
}
