如何从m3u8变量解析不同分辨率的m3u8 url？

I got the following m3u8 as php variable($returned_content). Now i want to replace proxy-63.somesite.com part of all m3u8 with video2.de.secondsite.net then create a hyperlink for each resolution and place all the hyperlinks in textarea.(for each resolution hyperlink i want to place the resolution of m3u8 in bracket after hyperlink title).

could any one tell me how i can achieve this task? Thanks in advance

PHP

$returned_content = get_data(''.$m3u8Url);


/* gets the data from a URL */
function get_data($url) {
    $ch = curl_init();
    $timeout = 5;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

    $link_text .="<a href=\"../Player.php?&vidID=".$m3u8Url."&title=".$title_name."\">".$title_name."."(".".$resolution.".")"</a><br/>
";
