I may be wrong, but that's exactly what I ended up having to do... but don't quote me - I'm just learning OOP

I've got the following test code which should output 2, but outputs 1. The while loop creates it's own class object (which seems strange since it isn't explicitly instantiated by my code; I would think it would cause errors). The reason I created an object for my variable (actually, I started testing with regular strings) is that I've had similar scoping problems in perl, where variables got out of scope within loops (or even if statements). In perl, declaring an object outside these structures will protect it's scope. Not so in PHP I see. Can anyone explain this behavior? Do I have to create functions that return values every time I need a loop that modifies a variable? <?php class Ccust_data { function Cform_data() { $this->test = ""; } } $o = new Ccust_data(); $o->test = 1; while ($y = 0) { global $o->test; $o->test = 2; $y = 1; } echo "\$o->test = $o->test\n"; ?> -- Randy Perry sysTame Mac Consulting/Sales phn 561.589.6449 mobile email [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
