Finding and replacing variables in text

[Anon]

Hi i am building my site and I need some help with templates. So I have one template in mySQL database: " Welcome today is $date " how can i replace that $date with $date variable builded earlier in code to display something like Welcome today is 20.02.2002. "
So i want to find variables in template and replace it with its predefined values. Is that posible? How?

i cannot use that becouse i need that for templates so i donot know how many vars will be in text. I used eval() function but i must calculate all vars before it and i cannot put that part of code in a function.. If someone know how can i make a class of that contact me on ICQ: 118700359, MSN: [e-mail] or on [e-mail]
