I see you've done a great job here! But instead of going through the long hassle of procedural programming which is prone to errors, and relatively uneasy to maintain codebase, I think switching to object oriented style of programming would be more profitable!
PHP has advanced from the old mysqli ways to PDOs now, and as developers in this modern age, we need to start adopting these new trends.
Between, thanks for sharing this! It sure would come in handy to someone that has been having problems!
nice one...PHP!!!
