I have a question regarding static methods in PHP5.x. Specifically, it
seems that one can access member variables declared private from
static methods, just as you can from instance methods. I was
wondering if this is by design, or if this "feature" might go away. I
have worked up an example, hopefully it won't get mangled:
<?php
class TestClass
{
private $myVar;
public static function loadAllObjects()
{
$vars = array();
$tempVar = new TestClass();
$tempVar->myVar = "Example";
$vars[] = $tempVar;
return $vars; }
}
$test = TestClass::loadAllObjects();
print_r($test);
?>
This code executes fine on PHP 5.2.0 with no errors or warnings, even
though one might say that I have accessed the private $myVar from
"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 ...
