Description:
------------
Note that the documentation states "int" and not "bool". I think "bool" would be more suitable, since the value should be true or false.

Test script:
---------------
declare(strict_types=1);

ob_implicit_flush (true);

Expected result:
----------------
No TypeError.

Actual result:
--------------
TypeError.

It's not a bug it's a Feature Request.

http://php.net/manual/en/function.ob-implicit-flush.php
void ob_implicit_flush ([ int $flag = true ] )

*this is* at least a documentation bug becaus eyou CAN NOT pass true to a int param if you arrived in 2017 and using strict types - either the param is bool or the default *can npt* be a bool true and *yes* i was trapped by that too

ob_implicit_flush(true);

Fatal error: Uncaught TypeError: ob_implicit_flush() expects parameter 1 to be integer, boolean given

I kinda agree it doesn't make sense to disallow booleans, when internally the function clearly only ever uses a boolean. What are the most likely thing to do is to allow anything, and then convert them to a boolean value, something like this should probably do:

The parameter is bool as of PHP 8.0.0, and that ias also
documented.
