Parsing/Evaling to return true or false

[Alcar Lazuli]

Say I had fields in a database that had:

PHP Code:

$sysstat == 1 


PHP Code:

empty($sysmessage) 


PHP Code:

$sysyes < 1 


How would I go about parsing/evaling the codes to return a true or false value depending on the field in the database?

So if $sysstat equaled 2, then obvisously $sysstat == 1 would return false.

How would I go about doing this?

Thankyou.

you just have to get em out of the db, whenever you use $blabl == blabla it will return true or false automatically

Well, whenever I do parse it to a function for the actual processing, it always ends up turning out from:

"$blahblah == 1" to "$1". Everything returns "$1".

$1 isn't a legal variable name, how can anything return it?

Yes I understand that, but can you not use those variables in preg_replace() ?

I'm actually taking apart a piece of text using:

PHP Code:

$text = preg_replace("#<if \((.+?)\)>(.+?)(<else>(.+?)</else>)</if>#is", xscondition('$1', '$2', '$3'), $text); 


Now, I understand that the reason it is returning "$1" is because of the use of the single quotes, however I've tried most things, with trying to pass preg_replace() variables onto a function, and it just won't work.

Thankyou,
