I am having a problem in my PHP Programing. Do anyone know any free library or package that could support a Formula parser, such as I parse a string to a function, ( a + 4 / ( b * 2 ) ), a and b is a variable. It bring me a lot of problems. I found some of the code that is available in Java and .Net.

Thanks for your kindly concern.
