  • What type of encoding can I use to make a string shorter?

    - by Abe Miessler
    I am interested in encoding a string I have and I am curious if there is a type of encoding that can be used that will only include alpha and numeric characters and would preferably shorten the number of characters needed to represent the string. So far I have looked at using Base64 encoding to do this but it appears to make my string longer and sometimes includes == which I would like to avoid. Example: test name|120101 becomes dGVzdCBuYW1lfDEyMDEwMQ== which goes from 16 to 24 characters and includes non-alphanumeric. Does anyone know of a different type of encoding that I could use that will achieve my requirements? Bonus points if it's either built into the .NET framework or there exists a third party library that will do the encoding.

  • A pattern matching an expression that doesn't end with specific sequence

    - by patryk
    I need a regex pattern which matches such strings that DO NOT end with such a sequence: \.[A-z0-9]{2,} by which I mean the examined string must not have at its end a sequence of a dot and then two or more alphanumeric characters. For example, a string /home/patryk/www and also /home/patryk/www/ should match desired pattern and /home/patryk/images/DSC002.jpg should not. I suppose this has something to do with lookarounds (look aheads) but still I have no idea how to make it. Any help appreciated.

  • mysql replace accented characters

    - by pixeline
    Hi, i would like to generate strict alphanumeric character logins from users' first and lastname. Since many of them are foreigners, their names have special characters (é, è, ï, ...). I would like to remove the accents (e,e,i,...) in the logins. Here is my query. Is there a character set that does not contain accents? UPDATE contacts SET login=CONVERT(LOWER(CONCAT(firstname,'.',lastname)) USING utf8);

  • Change Variable back to original value after Regex matching.

    - by Brad Johansen
    I just "finished" expanding my Palindrome Tester, made in C#. To allow for phrases I added a simple regex match for all non-alphanumeric characters. At the end of the program it states " is(n't) a palindrome." But now with the regex it prints the no spaces/punctuation version of it. I would like to be able to print the original user input. How do I do that? Here is my program: http://gist.github.com/384565

  • What/Where are the Naming Rules for Controller actions in a Zend_Application App

    - by Alan Storm
    I've created a Zend_Application using the zf tool that's bundled with Zend Framework (1.96, if that matters) What at the rules for formatting action names and how those action names get translated into into URL paths, and where in the Framework codebase does this happen? I ask because I tried to create an action like public function createFooAction() { } and it wouldn't load with a URL like http://example.com/controller/createFoo BUT, the following did work public function createfooAction() { } http://example.com/controller/createfoo I also know non-alphanumeric characters get treated differently, and I'd like to know the base rules I'm dealing with.

  • Validation library PHP / Javascript

    - by pistacchio
    Hi, could someone recommend a PHP form validation library (that works independently outside of any php framework) that apart from doing all sort of basic validation (is empty, vs regex, is email, is alphanumeric and so on) can produce javascript code (ideally to work with jquery) to validate the very same form with the very same rules client-side and hence define validation rules in a single place and have a form validated both server and client side? Thanks.
