Enumeration in PHP
An enumeration is a set of constant values, each of which is given a descriptive name.
Each value in an enumeration corresponds to a preset integer. In your code, however, you can refer to an enumerated value by name, which allows you to create more readable code and also simplify your coding experience.
Enumerations provide an alternative to the #define preprocessor directive with the advantages that the values can be generated for you and obey normal scoping rules.

Preparing for the Zend Certification
I’ve been thinking about preparing for the Zend Certification since last year but never took it very seriously until yesterday when I decided that it’s time for me to make room for it. It seems like I’m having less and less time every single new day and If I don’t commit myself to it, It will never happen. Blogging about this experience is much better.
