In part of my script, I'm testing 2 variables - $price and $amount - to make
sure they're the same. If they're not the same an error message should come
up.
But the error message comes up even when they are the same. I've added a
small test to make sure of it:
if($price != $amount)
{
echo "|$price|$amount|";
}
I go the following result:
|24.95|24.95|As you can see, there is no extraneous invisible character in
either variable. Both are exactly the same. So why did they evaluate as
not equal to one another??
