Description:
------------
Can't call variable objects. Where as in PHP 4 you can!!

Reproduce code:
---------------
class bug_test {
function bug_test() {
//create a test var
$this->test_var = 'hello world';
}
function echo_test_var() {
echo $this->test_var;
}
function say_hello() {
$object = 'this';
$$object->echo_test_var();
}
}

//let show this bug!!
$test = new bug_test();
$test->say_hello();

Expected result:
----------------
Should print "hello world to screen"

Actual result:
--------------
Notice: Undefined variable: this in c:\www\php_newrust\bug.php on line 20

Fatal error: Call to a member function echo_test_var() on a non-object in c:\www\php_newrust\bug.php on line 20

Edited submission as I feel as it can be better catagorised

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. 

Thank you for your interest in PHP.

See #31068

I have found an interesting hack to make it work, which means the problem is the fact that the "$this" self reference object is not been seen as a variable.

class bug_test {
function echo_test_var() {
echo "hello world";
}
function say_hello() {
$this_ref =& $this;
$hack = 'this_ref';
$$hack->echo_test_var();
}
}

//let show this bug!!
$test = new bug_test();
$test->say_hello();

Hope it helps

Cheers

Jody

It's still not a bug. This is not supposed to work.
