[PHP-DEV] How to convert a string into a mathematical expression?

[Christodoulou Demetris]

Hi list.
I have strings that are mathematical expressions. These strings are
submitted through forms.
For example a string might be $a="1+cos(0.3)*x".
Is there a way to convert this string to a mathematical expression that can
be calculated?
Thanks in advance.
    DX.
