Answer 1

Try something like

$category = preg_replace('/^.*\/(.*)\.html$/', '$1', $url);

The regular expression matches everything (.*) from the start (^) of the string up until the last / (\/). Then, it matches everything (.*) again except for the .html at the end and expects the string to end after that ($).

The brackets around the second .* allow you to reference that part of the match in the substitution as $1.
