I tried your code and for a while it worked but all of a sudden, it stopped working.

curl version?

cURL version.

Hi

Can anybody tell me why this code works on localhost, all stations I try, but 3 or 4 will not when on a server

PHP version 7.4 on localhost all stations work - server PHP version 5.5 about 3-4 do not work.

I tried all PHP versions available on the server and only 5.5 works at all

Hello,
When I run the script it returns the Artist and Title correctly but it does not update automatically when the next track plays.
Is this possible or do I need extra code to achieve this?

@rthymis You can achieve this by 2 ways (okay, there are more ways, but I'm giving common ones) - create cron task on server or call this script with AJAX request.

Hello, I’ve been using this snippet in my foreign music internet radio for few months now and its working great… !
I’m not a php programmer, a developer did this work a while ago. I have basic programming skills.
Right now, I ‘m trying to build a new internet radio that will play Greek music.
All the tracks that play there have Greek characters for Artist and Title in their tags.
AIMP player plays the stream and picks up the Artist / Title metadata (directly from the mp3 stream), and displays them correctly in Greek no problem as Artist and Title.
The Greek radio stream is : https://streamyourdream.org:8138/stream and the foreign music radio is https://streamyourdream.org:8050/radioactive

Using this php snippet (from fracasula) (which is a part of my API), see here https://radioactivefm.gr/live/api/getSongJson.php, I modified the calling code for the new Greek radio and created this https://radioactivefm.gr/live/api/getGreekSongJson.php but it never returns anything!

When I changed the MP3 tags to English characters in one track and called the getGreekSongJson.php then it did work fine, so the function isnt't working with the Greek character set.

Here's the phps that I use:
