#Toolbox

A collection of useful php code I used to write pretty often. Actually in a really early state (i also commit untested and unfinished code).

Collections

ChainableCollections

Allow chaining of array access on a collection, useful f.e. for configuration. Chaining on a default \ArrayAccess implementation would lead to an error (if error level is sufficient) and strange behavior:

$obj = new \ArrayObject();
$obj['undefined_index']['undefined'] = true;

$obj['undefined_index'] will evaluate to null and null['undefined']to an array

$obj = new ChainableArrayObject();
$obj['undefined_index']['undefined'] = true;

Will result in a properly nested array/collection structure, without throwing notices/errors. Furthermore it introduces a fluent interface:

$obj->set('index', $value)->set('another_index', $another_value);

Tree

In rally early state, hadnt got the time to fix and implement it properly:

Todos:

• think about the possibilities of the interface combinations to get an inheritance structure that makes sense (interface inheritance limits the advantages of the different interfaces)
