How to Extract the Last Segment of a URL in PHP?

Retrieving the Final Element of a URL in PHP

Determining how to isolate the final portion of a given URL can arise as a common programming requirement. PHP provides several robust mechanisms to achieve this objective.

Solution 1: Employing basename()

One straightforward approach is utilizing the basename() function, which conveniently extracts the final element of a URL path:

echo basename('http://example.com/artist/song/music-videos/song-title/9393903');
Copy after login

This will yield the expected output:

9393903
Copy after login

Solution 2: Leveraging parse_url() and pathinfo()

For more nuanced URL parsing requirements, consider implementing the parse_url() and pathinfo() functions in tandem:

$parsedUrl = parse_url('http://example.com/artist/song/music-videos/song-title/9393903');
$id = pathinfo($parsedUrl['path'], PATHINFO_BASENAME);
echo $id;
Copy after login

Further Considerations

Whichever solution you select, bear in mind that if the URL includes a query string, it will be incorporated into the returned value. In such instances, additional processing may be necessary to isolate the desired id.
