That comes in with php which is with mysql
PHP is not with MySQL and MySQL is not with PHP. They might be seen as twins that walk hand in hand, but they're two independent languages (for different systems) to each other. Or what do you think why SQL injection is possible?
I did tell you I was 12 but you didn't check properly and yes and I can program but when I get stuck I start to look on the internet and find a good template
Using templates will avoid the progress of learning. Usually when I find any templates in the web I write them down on my way understanding whats going on instead of copying and pasting. I build my own system and look for improvements, I learn what I steal if I really have to steal.
Yes, "why to invent the wheel again?" you may ask now? On professional development (where you get paid for every working hour) it's pretty fine to use any systems other programmers programmed already. But on learning progress (you still have 6 - 10 years, happily much to become a real development professional) you should invent the wheel tons of times on different ways on your non paid projects.
Even I catch myself rewriting a lot of things to improve it's performance, security and compatibility. One year ago I jumped over my shadow learning java script on a serious way. After a month the result was to rewrite over 2 thousand lines java script of my code to something shorter and more cleaner, because I did it the horrible way before. So, even If I wasted the time on the productivity way before, the result is better and now I know
how to do it right.
Regarding your age and skills: Even If your age is very low, there is no need to use this as reason for releasing stuff and expecting others to be careful with you. As non programmer (yes, I do call you that) and as child, you should not release anything that other newbies might read because it's bad programming and will lead them into the wrong direction. In fact your position here is looking other well programmed projects and learning from it like the other beginners, perhaps ask some questions. That's all.
The best is you would understand to count and calculate the world of the binary number system as first, hexadecimal as next. Then you should lead to C doing ugly console programming, then you will learn what's really behind the scene. Do not take this as attack, everybody starts small and I'm happy to see there is a 12 years old boy/girl who got interests in programming.
Take it as constructive critism.
