Yes, you are right. They only work if the variable is not defined.

All, I've been poking around with these two functions while testing the build from CVS, and am not sure how they're supposed to work. From what I can gather, they are only called when changing a variable that wasn't in the class definition. I say that because I took the example script from http://uk.php.net/zend-engine-2.php and stripped it down to this: <?php class Setter {public $n; public $z;function __get($nm) { print "Getting [$nm]\n"; }function __set($nm, $val) { print "Setting [$nm] to $val\n"; }} $foo = new Setter(); $foo->n = 1; $foo->z++; $foo->z++; ?> That script outputs nothing, despite reading and writing to z twice, and writing to n once. If you comment out the "public $n;" and "public $z;" lines, you get the following output: Setting [n] to 1 Getting [z] Setting [z] to 1 Getting [z] Setting [z] to 1 ... which is what I was expecting. Are __get() and __set(), then, only supposed to work with non-declared variables, or am I doing something wrong?
