Description:
------------
---
From manual page: https://php.net/sessionhandler.gc
---
There seems to be data type mismatch on the documentation page https://www.php.net/manual/en/sessionhandler.gc.php where in the method declaration it is mentioned INT as a return type but later in the Return Values section it is mentioned BOOLEAN (TRUE, FALSE) type.

Test script:
---------------
I defined gc method for a custom session handler as:

public function gc($maxlifetime): bool

and it worked as expected. Platform: Debian 10, PHP 7.3.14

As of PHP 7.1.0, the return type is actually int, and is supposed
to be the number of garbage collected (i.e. deleted) sessions.
Previously, the return type was bool, signaling success or
failure.

This has been fixed in the meantime[1].
