It appears the proto in the sources is wrong. ::destroy() either
returns FALSE or itself, see
<https://github.com/vitoc/gmagick/blob/master/gmagick_methods.c#L762>
<https://github.com/vitoc/gmagick/blob/master/gmagick_methods.c#L769>

Indeed, then when should document it as returning Gmagick|bool, I guess.

I just tested however, and can't get it to return false, even when destroying it multiple times:

$g = new Gmagick();
echo get_class($g->destroy()); // Gmagick
echo get_class($g->destroy()); // Gmagick

I just opened a bug on GitHub, I suggest we wait for the feedback of the extension author before we update the doc!

The issue has been fixed on GitHub, destroy() can only return bool now:
https://github.com/vitoc/gmagick/commit/d7dc731608c32147b10d8f1f8a80eabb71577b13

So the doc should reflect this:

public bool Gmagick::destroy ( void )

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
