Decoding gzip (using PHP sockets)

Question

Ok, so there is this PHP implementation of Last.FM API some guy wrote and I'm using it for a small project of mine. His implementation doesn't request gzipped data from Last.FM servers so I decided to modify his implementation to work with gzip to reduce bandwidth. I have no problem in requesting gzipped data, that works just fine and all the data comes compressed (checked). The problem is decoding it. I'm pretty new with PHP and I was trying to decode it for the last two days but nothing I tried worked. :D

Here is the function that asks for and receives the data. If anyone could please help me make this function decode the data I'd be really grateful.

function send ($msg) {
    // Send message over connection
    fwrite($this->handle, $msg);

    $response = array();
    $line_num = 0;
    while ( !feof($this->handle) ) {
        $response[$line_num] =  fgets($this->handle, 4096);
        $line_num++;
    }

    // Return response as array
    return $response;
}

where $this->handle is

    $this->handle = fsockopen($this->host, $this->port, $this->error_number, $this->error_string);

Thank you =)

Have you tried something like...

$response='';
while(!feof($this->handle)) {
  $response.=fgets($this->handle, 4096);
}
$response=gzdecode($response);
return explode("\n",$response);

Im assuming that the whole response is gzipped and not each line individually. If it's each line you just need to change fgets() into gzdecode(fgets())..
