How to access variables outside a class

[Anon]

This is the problem:
When I create a class, I'm not able to access the global variables. For example in the following code:

<?php
class MyClass {
function return_address() {
return $REMOTE_ADDR;
}
}

$myObj = new MyClass();
print $myObj->return_address();

?>

I don't get any output. For some reason the function inside the class is not able to access the environment variable. The same problem also persists with form value. If I passed a value like username=sridhar, then when I try to access $username from within MyClass, then the value returns as an empty string (NULL).

Can anyone suggest a solution? (Please feel free to contact me via e-mail if you wish not to reply this message).

Thanks,
Sridhar

PHP handles globals differently from other languages. They are not accessible inside a function unless you declare them.

function return_address() {
global $REMOTE_ADDR;
return $REMOTE_ADDR;
}
