PHP used to allow both square brackets and curly braces to be used interchangeably for accessing array elements and string offsets. The curly bracket syntax is only allowed in a limited set of cases and can be confusing for people not used to it.
PHP 7.4 will deprecate the curly brace syntax for accessing array elements and string offsets and it is expected that support will be completely removed in PHP 8.0.

When adding a Custom Link and leaving the "Link Text" field empty, WordPress used to set a default fallback text: "Menu Item".
The changes in [36379] broke this behavior making the fallback text: ` (Pending)`, with a leading space.
Pending major refactoring of the Menus page (which is going to use a block-based user interface) this change just restores the original behavior by adding the fallback text to the related AJAX response.

Noteable changes:
- The `magic_quotes_runtime` and `magic_quotes_sybase` settings were removed in PHP 5.4, so no longer need to be set.
- Some functions that use external libraries can generate errors that can't be tested for, so are globally allowed to silence errors.
- Quite a few functions would cause errors if `safe_mode` was set. This setting was removed in PHP 5.4.
- Only a handful of `header()` calls needed corresponding `headers_sent()` checks for unit tests to pass, but more may need to be added as the nightlies builds are tested.

- Introduces `wp_get_missing_image_subsizes()` and `wp_update_image_subsizes()` to generate image sub-sizes that are missing or were not created after the upload.
- Adds a way to display errors that happened while creating sub-sizes.
- Introduces `wp_create_image_subsizes()` intended for use after an image was uploaded. It saves/updates the image metadata immediately after each sub-size is created. This fixes the (long standing) problem when some of the sub-size image files were created but there was a timeout or an error and the metadata was not saved. Until now such uploads were considered "failed" which usually resulted in the user trying to upload the same image again, creating even more "orphan" image files.
Note that the patch also includes some unrelated WPCS fixes.

Introduces the faux primitive capability `view_site_health_checks` available to single site admins and multisite super-admin to view the site health page within the admin.
The capability is mapped to the `install_plugins` capability without being dependent on the file system being writable. This fixes a bug where the feature couldn't be used by sites unable to write to the file system or managed through version control.

Use of `date()` in core depends on PHP timezone set to UTC and not changed by third party code (which cannot be guaranteed).
`gmdate()` is functionally equivalent, but is not affected by PHP timezone setting: it's always UTC, which is the exact behavior the core needs.

Adds `role="presentation"` to the `<table>` elements used for layout purposes.
Ideally, HTML tables should be used for tabular data. When tables are used for layout purposes, it's important to remove any native semantics so that assistive technologies can correctly announce the table content in a linearized fashion.

When viewing Site Health for a multisite install, there are a few recommendations that are not appropriate and could have negative implications for other sites on the install if the administrator follows the advice provided.
For example, Site Health recommends that inactive plugins and themes for a site should be removed. On a single site install, this is a great recommendation. However, on a multisite install, inactive plugins and themes for one site should not be removed because they could be active for other sites on the network.
This change also disables the `test_wp_version_check_attached()` test for multisite. This test checks for the presence of the `wp_version_check()` function on the `wp_version_check` hook, which is not present for every site on multisite.

This fixes several bugs in the signature verification code:
Disables signature checks on certain incompatible PHP versions that cause math errors when opcache is enabled;
Prevents a spurious URL and subsequent error when downloading a zip file with query arguments;
Prevents errors triggered by third-party upgrade scripts as per #46615;
Disables signature tests for Plugins, Themes, and Translations, leaving only core updates.
At the 5.2 release the API servers will only provide signatures for core update packages, which is why messages are suppressed for plugins and other package types. Signatures for those other items will become available later.

Currently, there are a number of scenarios where `is_block_editor()` (and `WP_Screen::is_block_editor`) would incorrectly indicate block editor support at different points of the loading process. Most notably, checking `is_block_editor` when hooking into the `current_screen` action will always result in `false`, even when the block editor is being loaded. This is because `is_block_editor` is not set to `true` until `edit-form-blocks.php` is included.
This change adds logic to `WP_Screen` to ensure the accuracy of `is_block_editor` on block editor pages earlier in the load process.
While edit screens will now be accurate 100% of the time from `current_screen` on, there are still a few edge cases where `is_block_editor` could contain an incorrect value when creating a new post.
Because a `WP_Post` object is a required parameter for the `replace_editor` filter and `use_block_editor_for_post()` function, `WP_Screen` will fall back to the value returned by `use_block_editor_for_post_type()` for the post being created. To eliminate these edge cases, the `use_block_editor_for_post_type` filter can be used to return the appropriate boolean value to indicate support.
