SplFixedArray::valid() is unavailable

[divinity76]

Description

The following code:

<?php
(new SplFixedArray(0))->valid();

Resulted in this output:

    Fatal error: Uncaught Error: Call to undefined method SplFixedArray::valid() in /in/9mO1i:2
    Stack trace:
    #0 {main}
      thrown in /in/9mO1i on line 2

    Process exited with code 255.

But I expected this output instead:

(blank)

I don't see any notice about SplFixedArray::valid being deprecated/removed in the documentation, and there's no mention of it in the PHP8.0.0 changelog https://www.php.net/ChangeLog-8.php either,

but it has been unavailable since PHP8.0.0.

From php/php-src@4222ae1

SplFixedArray is now an IteratorAggregate and not an Iterator.
SplFixedArray::rewind(), ::current(), ::key(), ::next(), and ::valid()
have been removed. In their place, SplFixedArray::getIterator() has been
added. Any code which uses explicit iteration over SplFixedArray must now
obtain an Iterator through SplFixedArray::getIterator(). This means that
SplFixedArray is now safe to use in nested loops.

From https://www.php.net/ChangeLog-8.php#8.0.0

SplFixedArray is now IteratorAggregate rather than Iterator.

We should probably document this better though, e.g. add a changelog to https://www.php.net/manual/en/splfixedarray.valid.php and the other methods indicating when they were removed

Sounds like a documentation issue then. Can someone move it?
