Little problem

[LogicalDohnuts]

Hey guys, I'm trying to read a game data file and it's listed like the following:

seta sv_maxRate "5000"

and I'm trying to read the file which is working, but I want to echo off what's in those quotes. But it doesn't seem to working. Could someone explain to me the problem here?

        <?php
                $myFile = "****/config_mp.cfg";
                $fh = fopen($myFile, 'r') or die("Can't read file");

                while(!feof($fh))
                {
                 $GetInfo = fgets($fh,filesize($myFile));
                }

                fclose($fh);    
                
                $values = explode('" "', $GetInfo);
                echo "Name: " . $values[2]; 
                
?>
