replace a word on variable value on php and using it on elseif statements

Question

If i have a variable like this on php :

$codition = "question_1 == a AND question_2 == b";

is there any way to replace the value to be like this :

$codition = "$question_1 == 'a' && $question_2 == 'b'";

This variable I can use in this condition:

 if(echo $codition){
     echo "Success";
 } else {
     echo "fail";
 }

The reason I use a variable on condition (if else) because I have a rule in the database, and the value looks like the first value on the variable $codition , is it possible to replace a word on variable and using it on elseif statements?

I think you are off track entirely with your question. Below I attempt to get at your question, but making an educated guess at what you are asking.

Assume:
Var $codition is a condition to check if 'a' or 'b'
Vars $q1codition and $q2codition are used to hold these strings 'a' and 'b'

Then:

$q1codition = 'a';
$q2codition = 'b';

if($codition == $q1codition && $codition == $q2codition){
 echo "Success";
 } else {
 echo "fail";
 }

Is this what you are getting at?
