Hi guys
If I want to input a function (for example x = 2y + 5) and then have it
stored in a database, so next time when I input the values for x and y, I
would like php to retrieve the function and compute it. I know how to store
and retrieve, anyone got any ideas about writing a parser to parse the
function? I've wrote parsers under lisp and other languages before just not PHP. If
someone wrote something like this or know of something like this, I'd rather
not have to reinvent the wheel.
Thanks
John
Hi John,
Take a look to the eval() function, sure it can help you about this.
Hope it helps, Jordi.
