When you need to perform an action on a single row of data, many people turn to cursors. Cursors come with a lot of overhead in the database engine and can be confusing. Here's a way to get the same results without the overhead in a much simplier way.

Mass email list of email addresses from a mysql db table.

Simple chatting script to be placed on a corner of a website
Also a good example how to use ajax.

Pull items from a mysql db table and display in the following format-
item1, item2, item3

In the example code, the query will return all items that have the color "red" specified in the db.

Display contents of a folder, see comments in code.

Generate multi select box from data in db, then when submitted, each selection is written to a db table as it's own record, each tied together by a common record id.

Get the count of records from DB

With this function you can calculate the age of a person

Example:
echo "Age is: " . age("1984-07-05");

Result will be (23 Feb 2005) = "Age is: 20"

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.
