Is it possible to implement an array-like object in PHP?

Question

I want to implement an object that behaves like an array. It should be used in this way:

$var = new CustomCollection(retrieveFromWebService());
echo $var[0]; // legal
$var[0] = 'a'; // illegal

Can this be done in PHP, using magic methods or another mechanism?

Your CustomCollection class will need to implement the built-in ArrayAccess interface.

Is it possible to "partially implement" an interface?

nope. An interface requires the class to implement all of its methods unless the implementation is an interface or abstract class.

I think ArrayAccess is what you are looking for.
