Just my guesses as the documentation is a bit thin at the moment

There are a number of attributes you can give a class, TARGET_* and you
will get the sum of all those targets as an unified bit value. 0 if none
of the TARGET_* are set.

https://www.php.net/manual/en/class.reflectionattribute.php#reflectionattribute.constants.is-instanceof

this will give you something like typeof for the instance in question.

mmmhhh...

Are you sure?
An example? (here's mine below)

~$ cat /tmp/aaa
<?php

#[ATTRIB]
class TARGET_CLASS {

#[ATTRIB]
function TARGET_METHOD() {}

}

#[ATTRIB]
function TARGET_FUNCTION() {}

function TARGET_xxx() {}

$reflections = [
new ReflectionClass('TARGET_CLASS'),
new ReflectionMethod('TARGET_CLASS::TARGET_METHOD'),
new ReflectionFunction('TARGET_FUNCTION'),
new ReflectionFunction('TARGET_xxx'),
];

foreach ($reflections as $reflection) {
echo $reflection->getName() . ': ';
echo $reflection->getAttributes()[0]->getTarget() || "IS ZERO";
echo PHP_EOL;
}
~$ php /tmp/aaa
TARGET_CLASS: 1
TARGET_METHOD: 1
TARGET_FUNCTION: 1
TARGET_xxx: PHP Warning: Undefined array key 0 in /tmp/aaa on line 25
PHP Fatal error: Uncaught Error: Call to a member function getTarget()
on null in /tmp/aaa:25

REPEAT:
An example?

https://www.php.net/manual/en/class.reflectionattribute.php#reflectionattribute.constants.is-instanceof

typeof...???

No and yes, it wasn't really what I thought

I thought it would give the value of #[Attribute(Attribute::TARGET_CLASS|Attribute::IS_REPEATABLE)] (65)

but it only gives you

Attribute::TARGET_CLASS (1)
Attribute::TARGET_FUNCTION (2)
Attribute::TARGET_METHOD (4)

see: https://github.com/php/php-src/blob/cc2bf119519c8dd7d6afa2b63aa4ea8b014f205d/Zend/zend_attributes.h

You can see at the unitest: https://github.com/php/php-src/blob/cc2bf119519c8dd7d6afa2b63aa4ea8b014f205d/Zend/tests/attributes/020_userland_attribute_validation.phpt

typeof...???

just ignore this part.. typeof used in other languages when you want to
know what type something is of and I was hasty in my reply and guessed
without really reading.
