Re: [PHP] Static methods have access to private members

This code executes fine on PHP 5.2.0 with no errors or warnings, even

outside the instance of TestClass created in $tempVar.  This 
feature is useful to me because I'd like to create a static method 
on my DB-persisted objects that lets me load an array of all of a 
given type of object from a database, building each one without having 
to use setters/getters for each member variable (not because thats 
difficult, but because its nice to be able to have private members 
that can't be accessed at all from the outside world), while avoiding 
lazy loading.  So essentially, my questions is, is the above 
functionality intended?



Thanks!

Mmm pardon me if I am wrong but I think you have accessed the private 
variable using an instanced object inside the static method and what you 
are returning is fine... You did not access the private variable using 
$this-myVar ...

[PHP] Static methods have access to private members

methods, just as you can from instance methods.  I was wondering if this
