Given the class definition:
<?php
class Caller {
private $x = array('a' => false);
function __set($name, $value) {
echo "setting\n";
$this->x[$name] = 'foo'; // intentially ignore value
}
function __get($name) {
echo "getting\n";
return $this->x[$name];
}
}
$foo = new Caller();
$b = $foo->a = 'bar';
echo "b is " . $b . "\n";
/* output:
setting
b is bar
*/
?>
I sort of expected both __set and __get to be called. Is it
concievable to have them both called?
The other alternative If possible, is allowing a return value
from __set() and using that value for the rest of the expression.

First, let me assure you that this is not one of those shady pyramid schemes
you've been hearing about. No, sir. Our model is the trapezoid!
Hello Curt,
From http://us2.php.net/manual/en/language.operators.assignment.php
"The value of an assignment expression is the value assigned.
That is, the value of "$a = 3" is 3."
I take this to mean that ($foo->a = 'bar') will always return 'bar'
and that is a core feature of the language. Remember that $foo->a is
the left hand operand, and is only receiving the value. It is the =
operator that returns the value of the expression.
It may also be worth noting that the Associativity of the = operator
is "Right".
