Practical PHP

Practical php is all about how to use php in the most practical way. There are many sites dedicated to PHP, and they all have thousands of tips and tricks on how to do things. But most of them require you to use external libraries such as PEAR, Zend and others to work. Or PHP-classes made by people you do not know, that all of a sudden does not get maintained. And then you are stuck.

And our experience is that once you do this your scripts start to become only a bit yours - if the external libraries change things break. And your customer complains that you have made an  error. And you have to look at code nobody really wants to touch again... 

We have always written our code to avoid this. If properly done , any php-script written in 1999 should still work. Al of ours do. And we are sure they will continue to do so.
