带有preg_match的PHP菜单

Question

First sorry for my bad English.

I have this menubar in PHP. I want that if an user is on a page the current menuitem gets another color. I had a code that works, but if i have a page like /item.php?id=9 , it wont work. So i tried this with preg_match, but i can't get it to work.

Menu :

<li <?php unset($pageURL); getSelected("/index.php") ?>><a href="index.php">Home</a></li>
<li <?php unset($pageURL); getSelected("/item.php") ?>><a href="item.php">Item</a></li>
<li <?php unset($pageURL); getSelected("/more.php") ?>><a href="more.php">More</a></li>

Function getSelected:

Function getSelected($nameURL){
$curURL =$_SERVER["REQUEST_URI"];
$pattern = "~$nameURL/.*~";
    if(preg_match($pattern, $curURL)){
        echo 'class="selected"';
        unset($curURL);
    }
    unset($curURL);
}

How can i fix this with preg_match?

Thank you!

I think basename() in combination with parse_url() would do the job. It returns the filename of an URL:

function getSelected($nameURL){
    $currentfile = basename(parse_url($_SERVER['REQUEST_URI'],PHP_URL_PATH));
    if($currentfile === $nameURL){
        echo 'class="selected"';
    }
}

And in HTML e.g.:

<li <?php getSelected("item.php") ?>><a href="item.php">Item</a></li>

No need for RegEx here.
