Re: [PHP] Eval()??? A variables contents?
I just asked a similar question yesterday. The answer is, conveniently enough, eval(). One trick from the php.net page on the function is to do somehting like this: $content = ?PHP Query_Database( $category );?; echo eval (?$content); Christopher Raymond wrote: PHP Gurus: I have one for you. I'm sure there is a simple solution, but I'm having difficulty finding it. Let's say I have: $content = ?PHP Query_Database( $category );?; If I use ?PHP echo $content; ?, it doesn't evaluate that content. What am I doing wrong here? Is there an equivalent to JavaScript's eval($commands) function?

However, I'm trying to get PHP to parse commands that are stored in a variable because I'm passing those commands to a function. Inside the function, it needs to evaluate the commands stored in the variable. Does you solution solve that or does my description clarify my problem better?
