Description:
------------
I think can be very usefull, sometimes, to be able to make a custom global variable, like languages, configs, etc.. and working just like $GLOBALS but only with the value/values assigned. I'm sure more than 75%-80% of the Php users will be agreed with this change.
Imagine and array with some translation strings:

$lang = array(
    'bla' => 'some nonsense talk',
    'blabla' => 'More nonsense talks');

and now the 'trick'.. some function to make 'global' the $lang:
make_global( $lang );

or even set in the php.ini some configuration like:
custom_globals = "lang, config, more, etc, bla, bla"

and now we can use it on global scope
function test() { return $lang['bla']; }

is a 'nicer' way than
function test() { return $GLOBALS['lang']['bla']; }
or
function test() { global $lang; return $lang['bla']; }


Test script:

-- none --

Expected result:

-- none --

Actual result:

I "flashed" the source code and founded the "zend_register_auto_global" and Im sure it can be done in the "php_startup_auto_globals" function or some other place, php_variables.c or zend.c just like:

    zend_register_auto_global("GLOBALS", sizeof("GLOBALS") - 1, 1, php_auto_globals_create_globals TSRMLS_CC);

but with our custom variable from php.ini for example.. just use ZEND_INI_ENTRY("custom_globals" ... and done ! :D
I know it can be done easy but now depend of you guys if you want to implement it or not.

If you really, desperately want this, you can use runkit, but not supporting custom autoglobals is a deliberate design decision: pervasive use of global variables is an anti-pattern.
