How can one extract wmsAuthSign from a URL using PHP and incorporate it into a real M3U8 URL?
To extract wmsAuthSign from a URL using PHP, you can use the parse_url function to get the query parameters and then parse_str to extract the value of wmsAuthSign. Once you have the wmsAuthSign value, you can incorporate it into a real M3U8 URL by appending it as a query parameter or adding it to the URL path.
$url = "http://example.com/video.m3u8?wmsAuthSign=abcdef123456";
$parsed_url = parse_url($url);
parse_str($parsed_url['query'], $query_params);
$wmsAuthSign = $query_params['wmsAuthSign'];
$real_m3u8_url = "http://example.com/real_video.m3u8?wmsAuthSign=" . $wmsAuthSign;
echo $real_m3u8_url;
