BTW:
Even if I try to use array_diff_assoc to have a "COPY" of $GLOBALS the
script gives me the same result.
I thing this is a very big problem without a "array_copy" function.
I tried:
<?
$xml=array("aaa", "bbb", "ccc");
foo();
function foo() {
var_dump($GLOBALS["xml"]);
$ar=array_diff_assoc($GLOBALS, array());
unset($ar['xml']);
var_dump($GLOBALS["xml"]);
}
?>

Is it documented? I didn't find this in the manual, probably this is a
documentation problem.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
This is a feature.

Description:
------------
In this script seems that the $GLOBALS value is changed by the unset
statement but I want to modify $ar, $GLOBALS must remain the same as
before.
Reproduce code:
---------------
<?
$xml=array("aaa", "bbb", "ccc");
foo();
function foo() {
var_dump($GLOBALS["xml"]);
$ar=$GLOBALS;
unset($ar['xml']);
var_dump($GLOBALS["xml"]);
}
?>
Expected result:
----------------
array(3) {
[0]=>
string(3) "aaa"
[1]=>
string(3) "bbb"
[2]=>
string(3) "ccc"
}
array(3) {
[0]=>
string(3) "aaa"
[1]=>
string(3) "bbb"
[2]=>
string(3) "ccc"
}
Actual result:
--------------
array(3) {
[0]=>
string(3) "aaa"
[1]=>
string(3) "bbb"
[2]=>
string(3) "ccc"
}
NULL
