Code Modernization: Add `AllowDynamicProperties` attribute to all (parent) classes. Dynamic (non-explicitly declared) properties are deprecated as of PHP 8.2 and are expected to become a fatal error in PHP 9.0. There are a number of ways to mitigate this: * If it is an accidental typo for a declared property: fix the typo. * For known properties: declare them on the class. * For unknown properties: add the magic `__get()`, `__set()`, et al. methods to the class or let the class extend `stdClass` which has highly optimized versions of these magic methods built in. * For unknown ''use'' of dynamic properties, the `#[AllowDynamicProperties]` attribute can be added to the class. The attribute will automatically be inherited by child classes. Trac ticket #56034 is open to investigate and handle the third and fourth type of situations, however it has become clear this will need more time and will not be ready in time for WP 6.1. To reduce “noise” in the meantime, both in the error logs of WP users moving onto PHP 8.2, in the test run logs of WP itself, in test runs of plugins and themes, as well as to prevent duplicate tickets from being opened for the same issue, this commit adds the `#[AllowDynamicProperties]` attribute to all “parent” classes in WP. The logic used for this commit is as follows: * If a class already has the attribute: no action needed. * If a class does not `extend`: add the attribute. * If a class does `extend`: - If it extends `stdClass`: no action needed (as `stdClass` supports dynamic properties). - If it extends a PHP native class: add the attribute. - If it extends a class from one of WP's external dependencies: add the attribute. * In all other cases: no action — the attribute should not be needed as child classes inherit from the parent. Whether or not a class contains magic methods has not been taken into account, as a review of the currently existing magic methods has shown that those are generally not sturdy enough and often even set dynamic properties (which they should not). See the [https://www.youtube.com/watch?v=vDZWepDQQVE live stream from August 16, 2022] for more details. This commit only affects classes in the `src` directory of WordPress core. * Tests should not get this attribute, but should be fixed to not use dynamic properties instead. Patches for this are already being committed under ticket #56033. * While a number bundled themes (2014, 2019, 2020, 2021) contain classes, they are not a part of this commit and may be updated separately.

Code Modernization: Deprecate dynamic properties in WP_Text_Diff_Renderer_Table magic methods. The unknown use of unknown dynamic property within the `WP_Text_Diff_Renderer_Table` property magic methods is now deprecated. A descriptive deprecation notice is provided to alert developers to declare the property on the child class extending `WP_Text_Diff_Renderer_Table`. Changes in this commit: * Adds a deprecation notice to the `__get()`, `__set()`, `__isset()`, `__unset()` magic methods, i.e. to alert and inform developers when attempting to get/set/isset/unset a dynamic property. * Fixes `__get()` to explicitly returns `null` when attempting to get a dynamic property. * Fixes `__set()` by removing the value return after setting a declared property, as (a) unnecessary and (b) `__set()` should return `void` [https://www.php.net/manual/en/language.oop5.overloading.php#object.set per the PHP handbook]. * Fixes `__isset()` to return `false` if not in the `$compat_fields`, as `isset()` and `__isset()` should always return `bool`: * [https://www.php.net/manual/en/language.oop5.overloading.php#object.isset `__isset()` in the PHP manual] * [https://www.php.net/manual/en/function.isset.php `isset()` in the PHP manual] * Adds a test class with happy and unhappy paths for these changes. For backward compatibility, no changes are made to the internal declared properties listed in `$compat_fields` and accessed through the magic methods. For example: A child class uses a property named `$data` that is not declared as a property on the child class. When getting its value, e.g. `$user_query->data`, the `WP_Text_Diff_Renderer_Table::__get()` magic method is invoked, the following deprecation notice thrown, and `null` returned: >The property `data` is not declared. Setting a dynamic property is deprecated since version 6.4.0! Instead, declare the property on the class. === Why not remove the magic methods, remove the `$compat_fields` property, and restore the properties `public`? tl;dr Backward compatibility. If a plugin adds a property to `$compat_fields` array, then sites using that plugin would experience (a) an `Undefined property` `Warning` (PHP 8) | `Notice` (PHP 7) and (b) a possible change in behavior. === Why not limit the deprecation for PHP versions >= 8.2? tl;dr original design intent and inform The magic methods and `$compat_fields` property were added for one purpose: to continue providing external access to internal properties declared on `WP_Text_Diff_Renderer_Table`. They were not intended to be used for dynamic properties. Deprecating that unintended usage both alerts developers a change is needed in their child class and informs them what to change.

Code Modernization: Deprecate dynamic properties in WP_Text_Diff_Renderer_Table magic methods. The unknown use of unknown dynamic property within the `WP_Text_Diff_Renderer_Table` property magic methods is now deprecated. A descriptive deprecation notice is provided to alert developers to declare the property on the child class extending `WP_Text_Diff_Renderer_Table`. Changes in this commit: * Adds a deprecation notice to the `__get()`, `__set()`, `__isset()`, `__unset()` magic methods, i.e. to alert and inform developers when attempting to get/set/isset/unset a dynamic property. * Fixes `__get()` to explicitly returns `null` when attempting to get a dynamic property. * Fixes `__set()` by removing the value return after setting a declared property, as (a) unnecessary and (b) `__set()` should return `void` [https://www.php.net/manual/en/language.oop5.overloading.php#object.set per the PHP handbook]. * Fixes `__isset()` to return `false` if not in the `$compat_fields`, as `isset()` and `__isset()` should always return `bool`: * [https://www.php.net/manual/en/language.oop5.overloading.php#object.isset `__isset()` in the PHP manual] * [https://www.php.net/manual/en/function.isset.php `isset()` in the PHP manual] * Adds a test class with happy and unhappy paths for these changes. For backward compatibility, no changes are made to the internal declared properties listed in `$compat_fields` and accessed through the magic methods. For example: A child class uses a property named `$data` that is not declared as a property on the child class. When getting its value, e.g. `$user_query->data`, the `WP_Text_Diff_Renderer_Table::__get()` magic method is invoked, the following deprecation notice thrown, and `null` returned: >The property `data` is not declared. Setting a dynamic property is deprecated since version 6.4.0! Instead, declare the property on the class. === Why not remove the magic methods, remove the `$compat_fields` property, and restore the properties `public`? tl;dr Backward compatibility. If a plugin adds a property to `$compat_fields` array, then sites using that plugin would experience (a) an `Undefined property` `Warning` (PHP 8) | `Notice` (PHP 7) and (b) a possible change in behavior. === Why not limit the deprecation for PHP versions >= 8.2? tl;dr original design intent and inform The magic methods and `$compat_fields` property were added for one purpose: to continue providing external access to internal properties declared on `WP_Text_Diff_Renderer_Table`.
