Incompatibility?

I'm wondering about something. I have the PHP3 application I wrote, very modular and makes extensive use of classes. a typical bit of code might loo like this : class foo { var $db = new DB_Connection; function do_stuff() { blah blah } } With PHP3 this seemed to work fine, in PHP4 I always get a parse error on the line "var $db = new DB_Connection;" or the like. I read this in the incompatibility section, it doesn't seem to apply to my problem but hey, thought I would ask. " Static variable and class member initializers only accept scalar values (in PHP 3.0 they accepted any valid expression). The impact should be small, since initializers with anything but a simple static value rarely make sense. " Thanks! Oh, I'm using PHP Beta4 pl1 and Apache 1.3.12 -Mitch
