Answer 1

Step 1. Search the string with strpos to find 'videojs("Player"' - the needle

Step 2. Remove the everything in the string from the position of the needle using substr

Optional Step : Find the last closing tag of the videojs - something like ");" and remove the remaining data with substr

Step 3. At this point you could use explode with the delimiter as the " (a bit hackish)

Step 4. This will now give you an array of each parameter that was enclosed in the ""

Step 5. You can now access the array get the required data.

<?php
    $url="http://abcast.net/embed.php?file=klaci16";

    $html = file_get_contents($url);
    $find = 'videojs("Player", ';
    $pos = strpos($html,$find);

    $html = substr($html, $pos+$find,-1); // Position + amount of characters of the needle
    $html = explode('"', $html);
    print_r($html); // What's the key?
    echo $html[11]; // 11 = http://live.abcast.net:8081/edge/verc9f615461d48dd8b44c84e0b87c50894/playlist.m3u8?wmsAuthSign=c2VydmVyX3RpbWU9OS82LzIwMTcgNTo1OToxOCBQTSZoYXNoX3ZhbHVlPVVPTElSQ3V4NENKM0FoQUhRUWJIYUE9PSZ2YWxpZG1pbnV0ZXM9MTIw
