A proof of concept idea I had for implementing an aspect oriented framework in PHP (yes, I know about http://aophp.net, but it requires a module).

I thought it was neat, so I'm going to share it.

Hope someone likes it.

Using the extract() Functio

This code, working with MovableType, creates a tag cloud of tags entered into the keyword field of a blog entry. You can see the results and read my write-up which explains some other things that help with MovableType and tag clouds. I got this code from Al-Muhajabah and made a few minor tweaks. Put the PHP snippet below inside a MT template that creates a php page.

Validate Email Address

This function simply splits a file based on the splitter supplied and returns an array with the values. It's pretty much like the file() function. This script could be helpful in section editings.

Genetic Algorithm implementation.

See also "Weighted random selection" for RandomItemSelector class source.

Based on "Random Password Generation"

This could be used for any type of simple hash checking. It could also be used to store a "password" that had to be verified. This code is completely managed.

Is this file the same as that file? The files may or may not be binary. We could compare the modify dates, or the sizes. But, those are not very accurate to know if a file has really changed.

Introducing MD5 Checksum. We can feed the files into Digest::MD5 in binary mode.

This is a great way to do Incremental Backups.

This is also an easy way to verify checksums when downloading files from the internet which list their MD5 Checksums.

You'll need the Digest::MD5 Perl Module.

A very simple yet very useful function to have around. Especially generating session codes, filenames or new passwords
