It seems to me that you are asking 1 of 2 questions:
1:
Can i pass a variable to a function? eg: func($var1, $var2);

The answer is yes.

2:
Will the value of $b in my example be the returnd value of the function?

the answer is yes.


If the function isnt working correctly when passing a variable to it, then the value of the variable is not the name of a collum in your SQL table.
