quick question -- precedence of variable

[Anon]

Hi,

when PHP looks for a variable, what is the precedence (order) in which it looks?

for example:

$HTTP_POST_VARS['term'] = 'hello';
$HTTP_COOKIE_VARS['term'] = 'Dolly';
$HTTP_SESSION_VARS['term'] = 'O Hello Dolly';

echo $term;

-- what is the order in which these collections will be searched through, is there a page on this at php.net?

Thanks

look in your php.ini file

variables_order = "EGPCS"
E - Enviornment
G - GET
P - POST
C - Cookies
S - Server - buitin vars

Registration is done from left to right, newer values override older values.
