Kurt:

I understand where you are coming from, and I appreciate your answer.
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?


Thanks,

Christopher

Re: [PHP] Eval()??? A variables contents?

2001-11-09 Thread Chris Hobbs 

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:

$content = "";
echo eval ("?>$content");

What you're doing doesn't make any sense.  If it were to work, it would look 
like the following:

 ; ?>,

or something similar.  I think what you want to do is:


that's using psuedo-code, of course.  You'll want to substitute correct php 
syntax for returning database results.
