I've just read that a var can be declared in php as follows:
string $var1;
integer $var2;
etc.

They aren't talking about casting.
I've never seen this before and trying it in vers 5.0.3.3 shows that it has
no idea about it either.
Am I missing something?
TIA
Vince

Looking at some of their examples seems whoever wrote them doesn't know
about it either.

well, the above is both casting and declaring...

// cast

(string) $var1;

// declaring

string $var1;

there are more formal ways to cast in php. and you know me, i'm kind of
religious about code. :)

i use things like floatval(), intval(), bool()...and then settype().

now for all of this casting and typing, php itself does precious little even
when it knows you've typed the data explicitly. really, it helps you in
comparisons in statements/functions (i.e. if/then, function()). it also
helps you get correct output to the browser...as in using sprint_f, or,
ooooh, how about implicit casting using number_format (even though a string
is returned).

anyway, hth.

Thanks Steve. I found if I use brackets it worked. I'm glad you cleared up
it's limited usefullness. Was beginning to feel like to C ish ;)

sorry, i should have shown the declaration too. it's only as a param that
will work, i.e.:

function hello(string $world);

anyway, hth...and no prob.
