PHP 8.2: Locale independent case conversion
- Locale sensitivity is almost always a bug
- Case conversion only really makes sense for ASCII (a-z|A-Z)
- Ignore non-ASCII characters

PHP 8.2: Deprecate partially supported callables
// Some callables are supported by call_user_func()
// but not $callable()
// Change to the following syntax
"self::method" -> self::class . "::method"
"parent::method" -> parent::class . "::method"
"static::method" -> static::class . "::method"
["self", "method"] -> [self::class, "method"]
["parent", "method"] -> [parent::class, "method"]
["static", "method"] -> [static::class, "method"]
// Can also use PHP 8.1 syntax
self::method(...) @brisphp1

PHP 8.2: Deprecate dynamic properties
class User {
public $name;
}
$user = new User;
// Assigns declared property User::$name.
$user->name = "foo";
// Oops, a typo:
$user->nane = "foo";
// PHP <= 8.1: Silently creates dynamic property.
// PHP 8.2: Raises deprecation warning
// PHP 9.0: Throws Error exception.
// Add #[AllowDynamicProperties] if necessary@brisphp1

PHP 8.2: Remove libmysql from mysqli
- libmysql and mysqlnd are bindings for mysql and PDO
- mysqlnd recommended since 5.4
- libmysql has worse performance and memory management
- mysqlnd is bundled with php
- libmysql still available with PDO
