I think the reason you're getting a parser error is nothing to do with
globals... you're giving it a value in the wrong place... it should be
like this...
class someClass {
var $password;
function someClass() { (or __Construct() in PHP 5)
$this->password = $GLOBALS['password'];
}
function someOtherFunctionInsideTheClass() {
$password =& $this->password;
// or you could probably even do this..
extract($GLOBALS);
}
}
but if you need it in every function of your class, I would just add a
reference in the beginnign of each function.. and that's it.. (that
shouldn't take that long...
function anotherFunctionOfTheClass ($arg, $arg2) {
$password =& $this->password;
}
maybe this will help? :)
