522656ed2b Coding Standards: Remove unnecessary ignore annotations in dbDelta().
It is perfectly possible to write a commented regex with layout for readability by using the `x` modifier.

As per the manual:
> x (`PCRE_EXTENDED`)
>
> If this modifier is set, whitespace data characters in the pattern are totally ignored except when escaped or inside a character class, and characters between an unescaped # outside a character class and the next newline character, inclusive, are also ignored. This is equivalent to Perl's /x modifier, and makes it possible to include commentary inside complicated patterns.
>
> Note, however, that this applies only to data characters. Whitespace characters may never appear within special character sequences in a pattern, for example within the sequence (?( which introduces a conditional subpattern.

Reference: [https://www.php.net/manual/en/reference.pcre.pattern.modifiers.php PHP Manual: Pattern Modifiers].

This commit rewrites these two regexes to use the `x` modifier and gets rid of the unnecessary `phpcs:disable` comments.

The tests in the `tests/phpunit/tests/db/dbDelta.php` file cover this change.

e28f97b887 Code Modernization: Use str_starts_with() and str_ends_with() in a few more places.
`str_starts_with()` and `str_ends_with()` were introduced in PHP 8.0 to perform a case-sensitive check indicating if the string to search in (haystack) begins or ends with the given substring (needle).

WordPress core includes a polyfill for these functions on PHP < 8.0 as of WordPress 5.9.

84e9601e5a Code Modernization: Replace usage of substr() with str_starts_with() and str_ends_with().
`str_starts_with()` and `str_ends_with()` were introduced in PHP 8.0 to perform a case-sensitive check indicating if the string to search in (haystack) begins or ends with the given substring (needle).

WordPress core includes a polyfill for these functions on PHP < 8.0 as of WordPress 5.9.

This commit uses `str_starts_with()` and `str_ends_with()` in core files where appropriate:
* `$needle === substr( $string, 0, $length )`, where `$length` is the length of `$needle`, is replaced with `str_starts_with( $haystack, $needle )`.
* `$needle === substr( $string, $offset )`, where `$offset` is negative and the absolute value of `$offset` is the length of `$needle`, is replaced with `str_ends_with( $haystack, $needle )`.

This aims to make the code more readable and consistent, as well as better aligned with modern development practices.

This commit replaces `0 === strpos( ... )` with `str_starts_with()` in core files, making the code more readable and consistent, as well as improving performance.

While `strpos()` is slightly faster than the polyfill on PHP < 8.0, `str_starts_with()` is noticeably faster on PHP 8.0+, as it is optimized to avoid unnecessarily searching along the whole haystack if it does not find the needle.

de505f0eac Formatting: Improve performance of esc_url().
This changeset indirectly improves performance of the commonly used `esc_url()` function by optimizing the low-level function `wp_kses_bad_protocol()` for the by far most common scenarios, which are URLs using either the `http` or `https` protocol.

For this common scenario, the changeset now avoids the `do while` loop. While for a single call to the `esc_url()` function the performance wins are negligible, given that `esc_url()` is often called many times in one page load, they can add up, making this a worthwhile improvement.

613091bce5 Code Modernization: Rename parameters that use reserved keywords in wp-includes/kses.php.
While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names.

This commit:
* Renames the `$string` parameter to `$content` in:
 * `wp_kses()`
 * `wp_kses_hook()`
 * `wp_kses_split()`
 * `wp_kses_split2()`
 * `wp_kses_bad_protocol()`
 * `wp_kses_no_null()`
 * `wp_kses_stripslashes()`
 * `wp_kses_bad_protocol_once()`
 * `wp_kses_normalize_entities()`
 * `wp_kses_decode_entities()`
* Renames the `$string` parameter to `$attr` in:
 * `wp_kses_one_attr()`
 * `wp_kses_html_error()`
* Renames the `$match` parameter to `$matches` in:
 * `_wp_kses_split_callback()`
 * `_wp_kses_decode_entities_chr()`
 * `_wp_kses_decode_entities_chr_hexdec()`
* Renames the `$string` parameter to `$scheme` in `wp_kses_bad_protocol_once2()`.

* `$allowedposttags`
* `$allowedtags`
* `$allowedentitynames`
* `$allowedxmlentitynames`

This commit aims to improve developer experience by displaying a more helpful message to explain a PHP fatal error further in the code if any of these globals are either not set or not an array.

Note Using `CUSTOM_TAGS` is not recommended and should be considered deprecated. The `wp_kses_allowed_html` filter is more powerful and supplies context.

21eb7900b3 Docs: Clarify the $allowed_protocols default value in various KSES functions.
Add a note that the parameter is optional and defaults to the result of `wp_allowed_protocols()`.

This affects:

* `filter_block_content()`
* `filter_block_kses()`
* `filter_block_kses_value()`

Includes synchronizing the `$allowed_html` parameter description for consistency.

9ba0095255 KSES: Allow assigning values to CSS variables.
The `safecss_filter_attr()` function allows using custom CSS variables like `color: var(--color)`. However, it did not allow assigning values to CSS variables like `--color: #F00`, which is common in Global Styles and Gutenberg.

This commit adds support for assigning values to CSS variables, so that the function can be used consistently in Global Styles and the future Style Engine in Gutenberg.

`<ruby>` element and its friends are used to attach annotation text onto a piece of text. This is especially commonly used in Japanese content, but it can also been seen in content of other languages like Chinese.

The set of elements to enable such functionality consists of `<ruby>`, `<rt>`, and `<rp>` in the [https://html.spec.whatwg.org/multipage/text-level-semantics.html#the-ruby-element HTML Standard], while some browsers (like Firefox) additionally support `<rb>` and `<rtc>` for more advanced formatting, which are not yet included in the official HTML spec, but can be found in a [https://www.w3.org/TR/html-ruby-extensions/ W3C extension].
