    .htaccess and regex

    I was using this to test my regular expression:

    http://regexpal.com/

    And tried to match

    http://www.website.com/index.php?=other things

    to pull out the index.php portion

    We've all seen

    ^(.*)/index.php or some variant, but it never works because .* is greedy and doesn't stop before getting through index.php.

    I tried the negative assertion
    ^(.*)(?!index.php), but again .* was too greedy. The fact that this failed was really surprising because when I just did /(?!index.php), every slash matched exceopt the one before index.php. You'd think using the * would help that along.

    Anyway, if you have any ideas, I'd appreciate it

    Evidently regexpal doesn't understand what '(some expression)' means. Try http://www.regextester.com/ for better results. For a free offline tester try this: http://www.weitz.de/regex-coach/ . Good luck

    /(.*)?index\.php/ gives you 'http://www.website.com/'
    /.*?index\.php\?(.*)/ gives you '=other things'
    and , of course,
    /(index\.php)/ gives you 'index.php'
