Interesting. I wouldn't have expected that. However, that is how it
should work. Check out table K-2 on this page:

'==' is a loose comparison. You can use '===' instead which will give
you the results you are looking for.

if $a == $b
and $a == $c
then $b should be equal to $c
No, not necessarily!
but php is saying otherwise?
Yes.
this sounds confusing i want to try n get my head round it

Thanks. It makes sense now.
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?

I'm sure many will disagree with me on this
I agree with Chris...
In contrast you can also see a common problem in many of the
downloadable scripts from different collections on the net, like
hotscripts.com, where the programmers start building control structures
whitout having the different variables they use set.
For instance
Hmmm, I don't think other programmer's sloppy coding practices are a
good argument for having to declare variables or against loose typing.

Exactly how a variable should be set, well it could be for instance var

Where on the php site does it tell you to set it like that ?

I dont understand, i assume that would check if name was set, i also set
functions like
function foo($name,$bar = null) {

so therefore bar doesnt need to be inputted, seeing as i set it to null
would i check if $bar===true ? or just isset($bar ) ?
when you have set
And $bar === true will only become true, if $bar is true, look at table

I challenge anyone to find a disadvantage in forcing decelerations of
variables and functions, other than having to type more.
Forcing declaration will create more list traffic...

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)

Hmm after all this time, are you saying its best to use === instead of

I would recommend using it whenever you can. It may require a few extra
lines of code here and there, but you know for sure what 'type' you are
dealing with. This is especially good when dealing

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