Have you ever spent hours trying to figure out why your PHP web page was not working properly? Do you hate having to add var_dump, var_export, or print statements whenever something is not working, only to remove them once you figured out the bug? Do you wish that there was a way to pause your code and see the contents of variables in your script? There is a PHP extension called XDebug that will allow you to do all this; it allows you to stop your script on demand, and will allow to run your script one line at a time. The process of running your script one line at a time is called 'stepping' through your program. XDebug allows you to step through your program, plus inspect variables, and even run some code while your script is paused. The unfortunate thing is that XDebug does not come with PHP by default, but the steps below will show you how to install and run XDebug. Then, I will show you how easy it is to debug scripts with Triumph 4 PHP.
