What potential issues could arise when using PHP to output .m3u8 livestreams?

One potential issue that could arise when using PHP to output .m3u8 livestreams is that the file may not be properly formatted, causing playback errors. To solve this, ensure that the .m3u8 file is generated correctly with the correct syntax and file paths.

header('Content-Type: application/vnd.apple.mpegurl');
$stream_url = "http://example.com/stream.m3u8";
readfile($stream_url);
?>
