How to extract the URL from this URL (via PHP)

[Badchip]

This URL opens a ".m3u8" stream: http://link.theplatform.com/s/pf1NfC/9buCiIMqXE9z

I'd like to extract the URL (via PHP)

Thank you in advance.

The easiest way is to use file_get_contents to get the contents of that file as long as your server is configured to allow that.

I tried with:

<?php
echo file_get_contents("http://link.theplatform.com/s/pf1NfC/9buCiIMqXE9z");
?>

but I obtain the contain of the stream, not the URL:

#EXTM3U #EXT-X-VERSION:3 #EXT-X-INDEPENDENT-SEGMENTS #EXT-X-STREAM-INF:BANDWIDTH=1100000,AVERAGE-BANDWIDTH=1100000,CODECS="avc1.77.30,mp4a.40.2",RESOLUTION=768x430,FRAME-RATE=29.970 master1000k.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=2420000,AVERAGE-BANDWIDTH=2420000,CODECS="avc1.4d401f,mp4a.40.2",RESOLUTION=1280x720,FRAME-RATE=29.970 master2500k.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=550000,AVERAGE-BANDWIDTH=550000,CODECS="avc1.4d4015,mp4a.40.2",RESOLUTION=480x270,FRAME-RATE=29.970 master500k.m3u8

I just need the second URL than opens http://link.theplatform.com/s/pf1NfC/9buCiIMqXE9z

That text is exactly what is inside that file.  If you open it with a text editor you'll see that.  If you don't want the contents of the file, what do you want?

[Badchip]

I just want the URL of the stream (http://stream.m3u8...") when you click http://link.theplatform.com/s/pf1NfC/9buCiIMqXE9z

I want to copy the code after ".m3u8?" in order to use it with another stream.

?hdnea=st=1510277838~exp=151027..................

Is it possible?

That server is redirecting one URL to another, it sounds like you want the URL that it redirects to.  You might need to use a library like cURL to send a request to that URL and get the headers back.  The redirection URL will be in the Location header.
