extracting text from file into vars

[master7]

I would like to know how to do this,
take a file that contains something such as this:

50,1,138,1000,50,96,(Everclear) - Heroin Girl

and put each value into its own variable ($var1, $var2, etc).

Any/all help would be appreciated.

<?
$file = "/path/file.txt";
$fp = fopen($file, "r");
$vars = fread($fp, filesize($file));
fclode($fp);
$vars = explode(",", $vars);
echo $var[0]; //would echo 50
echo $var[1]; //would echo 1
echo $var[2]; //would echo 138
//and so on.
?>
