Hi everyone,
I'm a php newbie. I'm sorry for the trivial question:
If I have two string variables like:
$Media_A = "8.00"
$Media_B = "8.86"
and I try to use this statement in order to make a subtraction
like:
$Media_B - $Media_A, result is 0!
Why????
It's like two strings has been converted into integers.
I say that, why, if I set $Media_B="9.86", new result is 1.
This example uses strings because values coming from a table where
field are defined varchar(7).
Is there a way to cast those variables and calculate the correct
differences between those two variables values.
thanx for help
Remo
