In this final tutorial of the series I'm going to show you how to manually trigger a destructor, and in addition you'll learn how to emulate the behavior of this magic method when using PHP 4.

They not only talk about how to call the destructor manually but they also show how to call multiple destructors at the same time to destroy lots of objects at once. And, as promised, they include a method for being able to use a destructor-like bit of functionality in a PHP4 app as well.

Here is a small PHP function I wrote that emulates a gradient fill of an image.

Disclaimer : there are probably existing alternatives or classes, maybe in PEAR. I didn't check. I wanted to write a function myself, as part of my GD training grounds.

The script is simple enough, and only uses four different variable values to make the patterns. There are a few examples of the end result in the form of a basic square output, but (as he mentions) it can be used just as easily in other situations. The source code is availible in either plain-text or in a .phps style file.]]> Tue, 14 Feb 2006 06:54:19 -0600
