<?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',
        'HTTP_GET_VARS',
        '_COOKIE',
        'HTTP_COOKIE_VARS',
        '_SERVER',
        'HTTP_SERVER_VARS',
        '_FILES',
        'HTTP_POST_FILES',
        '_REQUEST'
    ) as $var) {
        unset($globals[$var]);
    }
    print("<br />After...");
       print_r($globals);

    return $globals;
}

globals();
?>

array(7) { ["GLOBALS"]=> array(7) { ["GLOBALS"]=> *RECURSION* ["_POST"]=>
array(0) { } ["_GET"]=> array(0) { } ["_COOKIE"]=> array(0) { } ["_FILES"]=>
array(0) { } ["globalvar1"]=> int(1) ["globalvar2"]=> int(2) } ["_POST"]=>
array(0) { } ["_GET"]=> array(0) { } ["_COOKIE"]=> array(0) { } ["_FILES"]=>
array(0) { } ["globalvar1"]=> int(1) ["globalvar2"]=> int(2) }
Before...Array ( [GLOBALS] => Array *RECURSION* [_POST] => Array ( ) [_GET]
=> Array ( ) [_COOKIE] => Array ( ) [_FILES] => Array ( ) [globalvar1] => 1
[globalvar2] => 2 )
After...Array ( [globalvar1] => 1 [globalvar2] => 2 )

Ok I see it now.

Thank you all,
Ashim.
