I'm currently trying to program a URL shortener, but now I have the problem that I do not know how to program the forwarding.
I've made it so far that you can shorten a URL, e.g. you want to truncate the URL of YouTube, then create an entry in a database that "links" the YouTube URL to a randomly generated ID, say this ID is illustrative 'dzUejsg' Now I want to be redirected to the linked URL when entering sampleurl.com/dzUejsg, just I do not know exactly how to do that ...
I hope you can help me. Thanks in advance for all your answers! (Sorry for bad English, I'm german.)

If the ID stored in the database is extracted from the URL (ex. https://youtube.com/watch?q=123 and the ID is 123) then you could use the header("Location: $url") function.
For example:
$url = "https://youtube.com/watch?v=".$id; // Where id is the id from the database.
header("Location: $url");
TL;DR Use the header("Location: <location>"); function
