There are many PHP debugging techniques that can save you a great number of hours when coding. It is simply turn on error reporting and it can also help identify more evasive bugs by displaying what is actually going onto the screen.

if you want to do this like in other languages with debugger (C++, C# etc.) step by step, then you need an IDE with php support for instance Netbeans or Eclipse or Aptana studio. Then you need to install xdebug (or Zend debugger), configure php to make use of xdebug and you are ready to go. If you want to just check what sits in your variable you can use echo, var_dump, printf functions.

Yes, there are many techniques which are using for debugging PHP code. The Xdebug extension helps you debugging your script by providing a lot of valuable debug information.

The first step is to install IDE with PDT (PHP Development Tools). You should be able to fetch the latest version of Eclipse PDT for your operating system at the Eclipse downloads section. The installation procedure on my Debian box was trivial: download, extract and run. The only issue I run into was not being able to run Eclipse with PDT in a stable manner with anything other than Sun JRE.
