Scope???

[php4_23]

I have some code like this

require ("dbclass.php");
$db = new dbdriver();

function test() {

	$s = $db->dbQuery("SELECT * FROM members");
	if (!$s) {
		echo "crap";
	}else {
		echo "ahaha";
	}
}

test(); //call the function

Now this should work right?? But it says call to member object on blah blah blah.

This seems to me that the $db var is not usable inside the function.
help ??

You will have to declare the new object within the function... Maybe try passing the new object declaration as an argument for the function? Or just require the file inside of the function, and then do the object declaration inside as well...

function test()
{
global $db;

$db->whatever();
}

Thanks
I got it to work by passing the $db var a s a parameter. It also works by declaring it global.

Ahundiak, can you tell me why is works it i declare it global inside the function,....I mean I already delcared the variable outside the function (it should work like that)????

Anyways thanks again

It's discussed in the manual. PHP requires that you declare each global variable used by a function inside of the function itself. It's a bit unusual but it sure makes it clear when a global is being used.

So called 'super globals' ($GET,$POST etc.) are the exceptions to this rule.
