Declare variable as superglobal?

Hi -

Is it possible to change the status of a variable to superglobal so
it'll be valid inside functions without declaring it with "global"
inside each function?

Thanks -

Not as far as I'm aware, I don't think this is exposed through a PHP API.

I wonder if it's possible to write a loadable extension that could call the
appropriate Zend API to superglobalify a variable, though.

You are aware of $_GLOBALS right?

All you have to do is put it inside one of the superglobal arrays. Use
those arrays directly inside the function.

e.g. instead of

function donut(){
global $holes;
return $holes - 1;
}

do

function donut(){
return $GLOBALS['holes'] - 1;
/* or $_SESSION['holes'] or $_POST['holes'] or other superglobal */
}

However, the real answer to your question is DO NOT USE GLOBALS INSIDE
FUNCTIONS!!!! You are just asking for trouble down the line, take my word
for it.

re: Declare variable as superglobal?

I don't think that can be implemented. The list of autoglobals isn't
stored in a pre-request structure. If you append a new variable to it,
it's going to remain there after a script finishes executing. You can
certainly write an extension that uses its own autoglobals however.

Thanks,

My idea is to set variables like
$b="<BR>"
so it's kind of shortcuts.
If I use the super globals, I'd rather write "<BR>" directly.

Sorry for not explaining that in the first place.

define('br', '<br>');

echo br;

Great! The "define" did it.

Any Idea for the cases that I want to use a variable after all (for
counter or for mysql connection)?

Thanks again.

Good you elaborate on that?

For example, I hide the connecting stuff from everyday code. Looks
something like this:

class MySQL
{
private static $connection=null;
protected static function connect()
{
if (self::$connection != null) return;
self::$connection=mysql_connect('bla','blah','bla' );
// read from config...
}
public function query($sql)
{
self::connect();
return mysql_query(self::$connection,$sql);
}
}

In my everyday code I just have to

$result=MySQL::query('SELECT * FROM test');

No explicit connecting required. Of course you can go for functions but
I'm all for the OOP way (even if it's just static stuff like here).
