I have a global variable outside my class = $MyNumber;
How do I declare this as a property in myClass?
For every method in my class, this is what I do:
class myClass() {
private function foo() {
$privateNumber = $GLOBALS['MyNumber'];
}
}
I want this
class myClass() {
//What goes here?
var $classNumber = ???//the global $MyNumber;
private function foo() {
$privateNumber = $this->classNumber;
}
}
EDIT: I want to create a variable based on the global $MyNumber but
modified before using it in the methods
something like: var $classNumber = global $MyNumber + 100;
You probably don't really want to be doing this, as it's going to be a nightmare to debug, but it seems to be possible. The key is the part where you assign by reference in the constructor.
$GLOBALS = array(
'MyNumber' => 1
);
class Foo {
protected $glob;
public function __construct() {
global $GLOBALS;
$this->glob =& $GLOBALS;
}
public function getGlob() {
return $this->glob['MyNumber'];
}
}
$f = new Foo;
echo $f->getGlob() . "\n";
$GLOBALS['MyNumber'] = 2;
echo $f->getGlob() . "\n";
The output will be
1
2
which indicates that it's being assigned by reference, not value.
As I said, it will be a nightmare to debug, so you really shouldn't do this. Have a read through the wikipedia article on encapsulation; basically, your object should ideally manage its own data and the methods in which that data is modified; even public properties are generally, IMHO, a bad idea.
