Static members or not?

Hi
I am using PHP5 and the static members/variables doesn't
seem to stick.
PHP5 doesn't seem to care about the static keyword. It would
be nice to
get this working.

For example: In the code below, I never get a return before
the
print-line.

function getSelectedColumns($prj_id, $page)
{
        static $returns;

        // poor man's caching system
        if (!empty($returns[$prj_id][$page]))
            return $returns[$prj_id][$page];

	print("I always get here!");
        ...
       
$returns[$prj_id][$page][$field_name]="Jello"; 
        ...
}

Hi Jostein, is this a problem with the specific code below
or all cases
where static is used?

In my test on PHP 5, static variables work as expected.

Class monkey {
    function testStatic($foo)
    {
        static $blah;

        if (isset($blah[$foo])) {
            return "Static variable used<br
/>";
        }
        $blah[$foo] = 'FOOO';
        return 'No static<br />';

    }
}

echo monkey::testStatic(1);
echo monkey::testStatic(1);

echo "Version: " . PHP_VERSION;

Outputs:
No static
Static variable used
Version: 5.1.2

Ok, so the static members die on page reload.
Then I must say it works fine. 
It's indeed a 'poor man's caching system' :(
