wish of those help The interface ArrayAccess only works for objects. There's nothing similar for static access.
code :

should help you out Because array_filter only works with arrays.
Look at other options, like FilterIterator, or create an array from your object first.

will be helpful for those in need Demo creating the Tree on construct and Demo creating Tree on demand are simple tests you can run for yourself.
The latter creates new node objects only when they're accessed, thus the memory consumption is not that high.

I wish this helpful for you If you can easily create a Config instance from an array, that would be my preference. While you want to test your units in isolation where practical, simple collaborators such as Config should be safe enough to use in the test. The code to set it up will probably be easier to read and write (less error-prone) than the equivalent mock object.
code :
$configValues = array(
    'db_host' => '...',
    'db_user' => '...',
    'db_pass' => '...',
    'db_dbname' => '...',
);
$config = new Config($configValues);
$config = $this->getMock('Config', array('offsetGet'));
$config->expects($this->any())
       ->method('offsetGet')
       ->will($this->returnCallback(
           function ($key) use ($configValues) {
               return $configValues[$key];
           }
       );

I hope this helps . Static members in Java are allocated on one-per-class basis. Since there is only one per-class item for any static member, Java knows where each one of them is at runtime.
Therefore, the only issue here becomes visibility of the item from the point of view of access control. Here, too, Java has no issues, because Java compiler knows from where each static item can be accessed.
code :
StaticClass.show(); // this will compile from anywhere

To fix this issue The same behavior happens with any interface, so not specific to ArrayAccess.
In the PHP documentation Objects and Classes -> The Basics, there is a very terse hint (I put it in bold) in the new section:
