Now I have one more question. Not to confuse the issue more. :)
$EA = 0
if ($EA == "NFH") // would work because the string is converted to an
integer and then compared correct ?
And by using === I tell it to compare type and value ? If that is true
would 0 == "0

No this is not true, since types conversions can be different between a

Looks fine to me...
$test == $test2: $test

$test is equal to $test2,

I've come across this recently too. I think what's happening is that PHP is
converting "NFH" to an integer, which would be zero in this case. Thus zero
== zero is true...
Try doing type checking too:
if ($EA === "NFH")

When comparing strings either use '===' or one of the string comparison
functions.
