Answer 1

You might find it easier to grab the parameters in the .php file, via:

$pathinfo = isset($_SERVER['PATH_INFO'])
    ? $_SERVER['PATH_INFO']
    : $_SERVER['REDIRECT_URL'];

$params = preg_split('|/|', $pathinfo, -1, PREG_SPLIT_NO_EMPTY);

echo "<pre>";
print_r($params);

So calling the script with this:

http://www.example.com/variable1/variable2/variable3

would return:

Array
(
    [0] => variable1
    [1] => variable2
    [2] => variable3
)

This will work for both:

http://www.example.com/variable1/variable2/variable3 and http://www.example.com/process.php/variable1/variable2/variable3

You are only capturing one variable in your rewrite rule.

You need something like:

RewriteRule ^([A-Za-z0-9_-]+)/([A-Za-z0-9_-]+)/([A-Za-z0-9_-]+)/?$ process.php?width=$1&height=$2&third=$3 [QSA,L]

or, a bit shorter:

RewriteRule ^([\w-]+)/([\w-]+)/([\w-]+)/?$ process.php?width=$1&height=$2&third=$3 [QSA,L]

(the \w word character includes letters, digits and underscores)

I have made only the ending slash optional so this rewrite rule would only do something if there are exactly 3 variables.
