Lets code add methods to existing classes and interfaces from outside their definition, Swift-style.

Extends extension methods to built-in types like string, int and array.

Throws a catchable MemoryError for allocations that are obviously too large, instead of a fatal error.

Adds str_mask() for masking phone numbers, card numbers and other sensitive strings.

Allows the #[\Deprecated] attribute on interfaces.

Adds ReflectionAttribute::getCurrent() so an attribute can find the element it is attached to.

Adds a fallthrough; marker to switch and warns when a non-empty case falls through to the next one without it.

Adds path segment accessors to the URI extension so paths no longer need splitting by hand.

Adds a #[\NonExhaustive] attribute that marks an enum as likely to gain cases, so code matching on it knows to handle unknown ones.

Adds str_iter() for iterating over a string one UTF-8 code point at a time.

Adds FILTER_VALIDATE_STRLEN to validate string length in UTF-8 code points.

Adds a SORT_STRICT flag to sort(), ksort(), array_unique() and friends that orders values by type first, with no type juggling.

Lets __sleep() return null or nothing, so it runs as a pre-serialization hook and the engine then serializes the object as usual.

Adds a #[\NotSerializable] attribute that makes the engine refuse to serialize() or unserialize() instances of a class.

Adds BLAKE3 to ext/hash, so hash('blake3', ...) and hash_hmac() can use it.

Adds array_search_range() to search for a value within a slice of an array.

Adds a |>= operator so $x |>= trim(...) pipes a variable through a function and assigns the result back.

Function autoloading modeled on class autoloading, with no cost to calls that resolve normally.

Requires autoconf 2.71 to build PHP 8.6 from git, and MySQL 5.7.3 or MariaDB 10.2.4 for persistent connections.

Lets readonly properties declare default values, so a class can meet a get-only interface property with a fixed value.
