And as it is the same as eval it's quiet dangerous. And ereg is indeed deprecated. But this shouldn't be a big issue.

You should no longer use "ereg_replace", this is discontinued. I agree, there is no difference to using eval. You should no longer use “ereg_replace”, this is discontinued.

Took me a couple of seconds to realize what exactly you are doing but in fact its a very simple yet effective and most importantly eval-less aproach :) Thanks for the idea.

I'll use your code in my final project. thank you so much, after an hour searching, finally I found this website, calculate formula without eval(), look great.
