I give you Minify, a script which combines and compress your files on the fly. This way the files get smaller and the client only have to make one request to the server. Just include the class in the top of the page, somewhere before you include your CSS/JavaScript, give it a few parameters and it will do everything for you. Now you can have how many files you want and edit whenever you want as long as you include the CSS/JavaScript file generated by Minify.

But, won’t it slow down the execution of the page to run Minify every time? No! First of all, you’ll barely notice when the script actually runs because it doesn’t take any time at all. And second, it won’t run the script if there is no change to the source files. The script is smart enough to store the hash of every file in a cache file and will just check against it.

I made the function which Minify is based on a few months ago when I tried to figure out a way to compress my files automatically and I’ve used it for two or three projects. I realized that there should be an easier way to integrate the script into an existing code and that’s why I made Minify. The original script used PHP’s function filemtime() to check if a file had been modified since the minified version was generated. It work decently, but if you copy/paste an old file from another project it will still have the same modified time and therefore will the minified version be newer. This and a lot of other stuff were fixed when I changed to the existing system, which is faster too!

So, what’s next for Minify? Well, first of all I want to fix all the issues listed below and more optimization. A nice thing would be native JavaScript and CSS compression in Minify.class.php to keep it in one file. Can you think of something else to add? Suggest it!

Please comment below what you think about the script. Don’t be afraid to report issues, improvements, feedback etc. below and remeber to tell your friends!

Information

The JSMin Class is based on code by Ryan Grove and CSSMin Class is based on code by Corey Hart. Current version of Minify (r9) was released August 2nd, 2010.

Arguments

type     = type: enum(css,js) - required: yes - default: n/a
dir      = type: string       - required: yes - default: n/a
file     = type: string       - required: yes - default: n/a
filter   = type: array        - required: no  - default: array()
priority = type: array        - required: no  - default: array()
debug    = type: boolean      - required: no  - default: false

Example Usage

require 'Minify.class.php';
new Minify('css',
           'css/',
           'styles.min.css',
           array('fixIE.css', 'debug.css'),
           array('reset.css'),
           true);

Known Issues

• Minify will crash if it lacks the right permissions and/or the directory is not writable (fixed?).

These issues will most likely be fixed in upcoming releases of Minify. Stay tuned!

Change Log

• r9:
  • Updated CSSMin to latest trunk (7c4b536f1449eb7be3ca).
  • Added the current version of Minify to the debug output.
  • Minor code cleanup.
• r8:
  • Updated CSSMin to latest trunk (1ebdcc1ed7569ee7751bf17).
• r7:
  • Changed caching method again, this time to the SFV format (CRC32).
  • Remade the debug output. If the script doesn’t work it’ll be easier to find the cause.
• r6:
  • Fixed an issue where the script would include every file twice and ignore the priority array.
• r5:
  • Changed caching method for a faster and smaller cache. If problem occurs with this new release try to delete your old cache files.
  • Fixed a notice in CSSMin Class triggered by empty attributes in your stylesheet.
• r4:
  • Lots of code optimization.
  • Fixed the issue with files being compressed in alphabetical order and break thing. The new argument priority minifies the files in it before the rest. Perfect way to compress the jquery library before your jquery calls!
  • Fixed a bug where the cache would become empty and crash the script everytime.
• r3:
  • Public release!
  • The minified file (specified in the file argument) will now automatically be included in the filter argument to stop an evil loop which will minify the files every page load instead of using the cache.
  • The name of the class is now Minify instead of minify.
  • Made a few changes to the example usage.
  • Renamed the cache files from .md4 to .cache for better understanding of their functionality.
  • The cache is now checked against a hash in raw binary data instead of a hash in lowercase hexits for faster execution (like ~200 microseconds!).
  • Added a “Known Issues” section with all issues and their possible workarounds.
  • Spelling and grammar fixed is various locations.
  • Moved JSMin.class.php and CSSMin.class.php to the folder minify for better structure, will hopefully be integrated in the main file in a future release.
  • Cleaned up some whitespaces – everything for a smaller file!
• r2:
  • Deleted the folder “var”. The files are now included in the CSSMin class.
  • More comments in the code.
  • Added a bunch of options for the css compressor in CSSMin.class.php.
  • The CSSMin class shouldn’t fill the page with notices (temp fix!).
  • Example usage code.
• r1:
  • First test code produced.

I was writing a basic register-/login-script yesterday and when I did the part where it hashes the password with a salt I realized that there should be a more secure way to store passwords, so I wrote this function.

function salt($password, $username, $salt = 'b_Il-w63') {   

    /* Split the username and the password into two parts with "(string/2)+1" chars in each */
    $user = str_split($username, (strlen($username)/2)+1);
    $pass = str_split($password, (strlen($password)/2)+1);

    /* get the first character in the username and the password and convert them to its ascii value */
    $user_ord = ord($username[0]);
    $pass_ord = ord($password[0]);

    /* merge all variables into a special pattern */
    $string = sprintf('46%s-3S%s-%u-%s-%u-1a%s-F4%s', $user[0], $pass[0], $user_ord, $salt, $pass_ord, $user[1], $pass[1]);

    /* hash the string with sha512, and then it again with md5 */
    $hash = hash('sha512', $string);
    $return = hash('md5', $hash);

    /* reverse the md5 hash and return it */
    return strrev($return);

}

This way, even if someone can produce a rainbow table for the algorithm, and has the salt to do it with, they will never know where in the hash parameter the salts was placed, because they don’t know the length and first letter of the actual password. And of course we’ll salt it with a string (third parameter) which is hidden deep in a configuration file somewhere, which requires the skiddie to actually access your files to get it.

When the string is ready we hash it with sha512 and then again with md5 (less byte to store in the database) and after that the function returns the hash. One thing’s for sure, I’ll use this for all my projects .

This site is not finished yet, but will be in the upcoming weeks. The plan is to test the system a few months and then, if the site gets popular, expand to more games such as Modern Warfare 2 and Counter-Strike. Design is once again done by Fredrik Larsson.
