===============================
Rule ``ordered_class_elements``
===============================

Orders the elements of classes/interfaces/traits/enums.

Description
-----------

Accepts a subset of pre-defined element types, special element groups, and
custom patterns.

Element types: ``['use_trait', 'public', 'protected', 'private', 'case',
'constant', 'constant_public', 'constant_protected', 'constant_private',
'property', 'property_static', 'property_public', 'property_protected',
'property_private', 'property_public_readonly', 'property_protected_readonly',
'property_private_readonly', 'property_public_static',
'property_protected_static', 'property_private_static', 'method',
'method_abstract', 'method_static', 'method_public', 'method_protected',
'method_private', 'method_public_abstract', 'method_protected_abstract',
'method_private_abstract', 'method_public_abstract_static',
'method_protected_abstract_static', 'method_private_abstract_static',
'method_public_static', 'method_protected_static', 'method_private_static']``

Special element types: ``['construct', 'destruct', 'magic', 'phpunit']``

Custom values:

- ``method:*``: specify a single method name (e.g. ``method:__invoke``) to set
the order of that specific method.

Configuration
-------------

``order``
~~~~~~~~~

List of strings defining order of elements.

Allowed types: ``array``

Default value: ``['use_trait', 'case', 'constant_public', 'constant_protected', 'constant_private', 'property_public', 'property_protected', 'property_private', 'construct', 'destruct', 'magic', 'phpunit', 'method_public', 'method_protected', 'method_private']``

``sort_algorithm``
~~~~~~~~~~~~~~~~~~

How multiple occurrences of same type statements should be sorted.

Allowed values: ``'alpha'`` and ``'none'``

Default value: ``'none'``

``case_sensitive``
~~~~~~~~~~~~~~~~~~

Whether the sorting should be case sensitive.

Allowed types: ``bool``

Default value: ``false``
