<?

class test
{
	function staticFunction($a)
	{
		echo "\ntest::staticFunction($a)";
	}
}

echo "\nTest page\n";

echo 'function_exists=['.function_exists("test::staticFunction").']';

test::staticFunction(999);

call_user_func_array("test::staticFunction",array(999));

?>

Result:

Test page
function_exists=[]
test::staticFunction(999)
Warning: call_user_func_array() expects first argument, 'test::staticFunction',
to be a valid callback in bug.php on line 17

Must be:

Test page
function_exists=[TRUE]
test::staticFunction(999)
test::staticFunction(999)


(Please, don't write me stupid comments about method_exists()! Just read one more time function name.)
