I am unable to provide a better definition that user defined variables.
User defined variables are variables that are declared by the user. User
here means the creator (or maintainer of the script).
So for:
?php
$a = 'A';
$b = 'B';
$c = 'C';
function globals() {
$globals = $GLOBALS;
?php
$globalvar1=1;
$globalvar2=2;
function globals() {
$globals = $GLOBALS;
var_dump($GLOBALS);
print_r(br /Before...);
print_r($globals);
foreach (array(
'GLOBALS',
'_ENV',
'HTTP_ENV_VARS',
'_POST',
'HTTP_POST_VARS',
'_GET',
It doesn't though, it creates a copy of the $_GLOBALS super global array,
removes entries that will have been set by the system (i.e. it leaves
user-defined variables) and then returns the ones that are left, so in that,
the user note is perfectly correct.
What has me puzzled is how unsetting
Unsetting doesn't leave user defined variables. Unsetting simply destroys
variables (or removes elements from an array, etc). There is nothing magic
or hidden in that script. I think the note meant exactly what it said: after
creating a local copy of the $GLOBALS array and removing super globals

How does one remove user notes from php.net ?

I'd guest they had been granted access to the php.net page editor, but
I may be wrong. Not that that site hasn't been scraped by other sites

Dear Ashley,
I do follow the part when it creates a local copy of $GLOBALS.
When it unsets them, is there a subtlety of unset that it ONLY unsets system
defined entries? Could you please explain this ?
Thank you,
