Codenizer is very easy to use tool for analysis of PHP scripts - it will save you lot of time you would spend debugging otherwise. Its main use is to detect programming errors and bugs in scripts within seconds (no need to run the script).

Features: Codenizer is a PHP development too. It can analyze and validate your code without actually executing it. That can save significant amount of time in development. Finding the same problems later and debugging them out of the code can take a lot more time. Most common programming mistakes will get sorted out in this code writing phase. Codenizer can be easily integrated into many programming editors and IDEs so you can probably use it from within your favorite working environment. It can be integrated with an IDE such as the Eclipse, for example. It`ll show off the problems in the "problem" mode of Eclipse. It is able to catch a larger set of problems that PHP native checkers can do. The tool can be integrated with a range of other development environments and program editors too.

One important thing to note is that Codenizer doesn`t use the same parser as PHP interpreter but rather its own parser written from scratch especially for this purpose. What that means, and why is that important? Well, Codenizer will usually recover from almost any syntax error in your code and it will be able to report it to you and to happily continue parsing and analyzing code, although PHP interpreter would fail on first syntax error it encounters. In fact, there are other areas in which the native interpreter may work better. The optimal solution could be to use both.

Overall: This is a nice tool that enhances the capability of PHP programmers in writing error free code and cuts down on development time.
