Ignoring the 'assignment inside condition' arguments, is the return

I just found this behavior when trying to implement a linked list with php.
In linked list it's common to say:

Let's begin with a small code snippet:

function A( $selector ) {
switch( $selector ) {
case 1: $obj = new A_1(); break;

...
}
$this = $obj;
}
}
class A_1 {

It's common error with PHP and C.
You could make use of this like
if ($fp = fopen($filename,'r'))
since this is the same as
if (($fp = fopen($filename,'r')) == TRUE)
code after this line is executed when fopen() success to
