Adds PDO::PARAM_BINARY, as a new type or a flag, so PDO drivers bind and quote binary data the same way instead of treating it as a string or a LOB.

Deprecates a batch of features in PHP 8.7 for removal in PHP 9, each item voted on separately.

Adds native immutable vec, set and tuple types as typed alternatives to arrays.

Speeds up asymmetric visibility by resolving read and write access separately instead of re-checking on every write.

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

Lets the autoloader load an extension method's file the first time one of its methods is called, so the use extension import is all you write.

Scopes extension methods so they are only visible where they are imported with use extension.

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.

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

Allows the #[\Deprecated] attribute on interfaces.

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.
