I want to be a good programmer ....
any suggestion how to start
i am studying MySql and PHP
i know some JAVA HTML etc.

Do you really know java, or do you mean javascript?

If you know java then PHP will be no problem at all. If not, try http://webmonkey.wired.com/webmonkey/programming/php/ for some good information, as well as php.net of course.

Yup, php is a really easy language to pick up. Everything is basic and strait forward. Everything works very logically, just like java. (and unlike the very confusing c/c++ language, although powerfull, its alot of work)

Another place to start with the basics of php is http://www.w3schools.com/php/default.asp

And as mention http://php.net , you can use the search there to find function usages etc.
