Return to the PHP Code and Syntax Checker
PHPCodeChecker.com was built out of frustration for silly mistakes. I'd make them and even programmers I knew that were being paid high 5 figures were making them. Many of these mistakes went undetected: an IDE would not catch them either. Thus, I gathered up the most common mistakes I've made, focusing on those mistakes that wouldn't already be found, ensuring the tool would add value for everyone.
Finally, I designed it to be very fast, simple, and powerful. I was inspired by the very straight-forward nature of RegExPal.com, which is a much better website and incredibly powerful (and useful).
If you want to pay for it, consider buying my PHP book or turn off AdBlock/uBlock for this site. It makes no sense to charge for the service. It's about helping out developers so they can keep succeeding in creating great websites and services.
