This little function will split an e-mail address passed to it at the @ sign, and make sure that there is a valid e-mail server at the other end =)

This is a simple function that resizes and image using the GD add on for PHP.
Just a disclaimer: I know its not perfect, but i figured i would post it because the only other one on here is way confusing to some new PHP developers. Hopefully this one will help you learn how to use GD, and then you can write a better one.

I needed to send an email through an authenticated SMTP server. I found the snippet on the PHP website to do the trick.

Generate a random number or string in PHP.

Here's a basic function for debugging any kind of PHP variable. It allows for "invisible" or "visible" output--that is output in HTML comments or within visible HTML tags. It also supports customizable "containers" which lets you easily edit the look of the visible and invisible blocks. Examples in code below.

MySQL 5.x Stored Routines, PHP Session Values, a little CSS oh my! Complex to set up but easy to impliment. Geared toward security, simplicity (of use) and convenience.

This is a random password generator that produces understandable passwords based on word lists. I've only included a 3 entry world list because you should chose a list based on your password requirements and your users. If you need to generate passwords that are 14 characters in length, you will want a different list than if you're generating 8 character passwords. And depending on your users, you may want to use certain lists. The list I use is about 4000 words that are 5-7 characters long, all well-known words that have had potentially objectionable content removed. For security reasons I don't want to include this list.

A note on security: though this generates relatively strong passwords for the average user, they are particularly susceptible to brute-force attacks. This is even more an issue if somehow your word list gets compromised. I would not recommend using this function for anything where a highly secure password is needed.

A note on choosing your list: You'll also see that I've built the system to avoid generating passwords with zeros and ones in them. This is because zero and upper-case "o" can be confused as can one, lower-case "L" and upper-case "i." When choosing my word list I was also sure to strip out all words that start with the letter "o" or "i" (to prevent the optional ucfirst() from creating 0/O and I/1 confusion) and words that contain the letter "L" (to prevent l/1 confusion). I find that this greatly helps with preventing confusion, but again weakens the security of the passwords some. It's your choice.
