Creating images on the fly can be a very useful skill. PHP has some built-in image generation functions, further more, to generate new images or edit existing images on the fly using PHP, we need to have the GD library installed. In this tutorial we will show you how to get quite interesting and useful effects using image handling functions. We will review two practical tasks: creating security images (captcha) on the fly and building a bar chart using numerical values retrieved from MySQL database.

PHP is a great programming language. It's free, powerful, relatively easy to setup and learn, and it has extensions and frameworks available to do almost anything you could imagine. Frankly, it's just plain fun too.

But if you've never programmed before or have programmed before but not with PHP and want to learn it, wouldn't it be great to find a tutorial that conveyed the sheer joy of it? That's what I want to do!

There are tons of resources out there for learning PHP, but none of them are especially practical and most are boring rather than fun. They go over each specific command one by one, never tying it together, and spending (IMHO) too much time going over every possible variation of each command, with optional parameters that you probably won't need if you're just starting out.

The execution plan (often called the query execution plan or the explain plan) contains the individual steps a database goes through to execute a SQL statement. For example, execution plans provide information on which indexes are used, in which order access to the various tables occurs, and what algorithms are used for joins, sorting, and grouping operations.

The execution plan roughly corresponds to bytecode in scripting languages like Perl or Python – it is used internally to execute SQL statements. Creating an execution plan is sometimes also known as a compiling. However, this is more commonly referred to as the prepare phase ....
