accessing vars from within classes

Hello there!

I'd like to make some declared vars available to classes, such as:

$myVar = new MyClass(); //the var I want to be available to OtherClass
....
....
class OtherClass{
private $otherVar = $myVar; //seems to not work
...
}
?>

...and I wish to initialize $otherVar 'as is', I mean, without having
to pass arg through __construct(). The way I tried above doesnt seem
to work, unlike it would be in a function..

any idea ??

thanks a lot :)

Re: accessing vars from within classes

Yep, I believe global would work.

PHP:

$myVar = new MyClass();

class OtherClass {

private $otherVar;

function myMethod() {
global $myVar;
$this->otherVar = $myVar;
}
}

Re: accessing vars from within classes

I have a simple question, You are using classes because you want to be OO
rather than procedural. Why, then, would you expect what you did to work.
Instead, OtherClass should have accessor and mutator methods. It would bebe
executed as $otherClassInstance.setOtherVar($myVar) where
$otherClassInstance is and instance of OtherClass.

So, in summary, if you are procedual then stay procedural and if you are OO
then stay OO.

But of course. The scope of $myVar is lies outside OtherClass, so
$myVar is meaningless in the context of OtherClass.

And I wish to build a perpetual motion machine. Alas, the world does
not work that way...

It wouldn't work in a function either, unless you declare $myVar as
global.

Don't let your wishes control you; control your wishes instead.
