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.

This addresses an error on MySQL 8.0.22 or later:
{{{
Character set 'utf8mb4_unicode_520_ci' cannot be used in conjunction with 'binary' in call to regexp_like
}}}
From the [https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-22.html MySQL 8.0.22 changelog]:
> Regular expression functions such as `REGEXP_LIKE()` yielded inconsistent results with binary string arguments. These functions now reject binary strings with an error. ([https://bugs.mysql.com/bug.php?id=98951 Bug #98951], [https://bugs.mysql.com/bug.php?id=98950 Bug #98950])
WordPress meta queries use the `BINARY` data type for case-sensitive meta key comparisons using regular expressions. By explicitly casting the meta key to `BINARY`, we can make sure the values being compared use the same character set and produce consistent results.
The change is covered by existing meta query unit tests: three tests which previously failed on MySQL 8.0.22 or later now pass.

In the `WP_Meta_Query::get_sql_for_clause()`, the `'value'` index from a meta query array is passed to the PHP native `trim()` function without prior validation.
In PHP 8.1, this could lead to a `trim(): Passing null to parameter #1 ($string) of type string is deprecated` notice.
`trim()` expects a text string and is only useful when ''passed'' a text string as no other variable type can contain whitespace.
Fixed now by verifying that the ''value'' is a string before processing it with `trim()`.
This issue is already covered by the existing `Tests_Meta_Query::test_null_value_sql()` and the `Tests_Meta_Query::test_convert_null_value_to_empty_string()` tests.

`compare_key`, introduced in #42409, previously supported only `=` and `LIKE`
operators. This changeset introduces a number of other operators: `!=`, `IN`,
`NOT IN`, `NOT LIKE`, `RLIKE`, `REGEXP`, `NOT REGEXP`, `EXISTS`, and `NOT EXISTS`
(the latter two aliased to `=` and `!=`, respectively). To support case-sensitive
regular expression key comparisons, the new `type_key` parameter will force
a MySQL `CAST` when 'BINARY' is passed.

WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.
This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script.
- Auto-fixable coding standards issues will now cause Travis failures.

The new `compare_key=LIKE` parameter works in conjunction with `key` in a
similar way to the `compare=LIKE` and `value`: by doing a "compares" `LIKE`
query. This allows developers to do partial matches against keys when
doing meta queries.

Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

In order to allow meta-related values of `orderby` to be handled properly,
the term query's `meta_query` object must run its `get_sql()` method before
`orderby` parsing.
Fixing this bug required addressing another bug in `WP_Meta_Query`, which
caused the table alias index not to be reset when calling `get_sql()`
multiple times on the same object.

First-order meta query clauses are defined as clauses that have either a 'key' or 'value' array key. When using named first-order clauses in meta queries to order results in the parent query, `WP_Meta_Query` can additionally accept first-order clauses at the sub-clause level, which was not previous documented.

`CHAR` is redundant, since the `meta_value` column is `LONGTEXT`. Meanwhile,
use of `CAST()` causes MySQL to ignore any index that the administrator may
have added to the column.
A number of automated tests were doing searches for `CAST` in the SQL strings
generated by `WP_Meta_Query` (for reasons unrelated to the `CAST()` behavior).
These tests have been updated to expect the new query format.

Known functions, classes, and methods are now auto-linked in Code Reference pages following #meta1483.

By forcing all clause keys to be strings, we make it possible to use strict
comparison when validating values of 'orderby' as passed to `WP_Query`. This
eliminates situations where the presence of numeric clause keys could result
in an improperly validated 'orderby' value.
