When calling static methods, the function call is stronger than the static property operator:

Example #3 Variable method example with static properties

<?php
class Foo
{
    static $variable = 'static property';
    static function Variable()
    {
        echo 'Method Variable called';
    }
}

echo Foo::$variable; // This prints 'static property'. It does need a $variable in this scope.
$variable = "Variable";
Foo::$variable();  // This calls $foo->Variable() reading $variable in this scope.

?>


Test script:
---------------
<?php
class Foo
{
    static $variable = 'static property';
    static function variable()
    {
        echo 'method variable called';
    }
}

$variable = "variable";

echo "<br>" . Foo::$variable; // This prints 'static property'. It does need a $variable in this scope.
// Foo::$variable; == Foo::$variable This is not appended dynamic static variable

echo "<br>" . Foo::$$variable;
// Foo::$$variable; == Foo::$variable This is appended dynamic static variable

echo "<br>" . Foo::$variable();  // This calls $foo->Variable() reading $variable in this scope.
// Foo::$variable(); == Foo::variable()


?>

Expected result:
----------------
static property
static property
method variable called

Actual result:
--------------
static property
static property
method variable called
