Fix "PHP Notice: Undefined variable: GLOBALS"

[khorsky]

I'm getting this notice, so it looks like the presumption the variable exists is wrong...

I would resend this PR into official stream too, but it looks abandoned. And I'm using your hfig/MAPI, so I'd like to have it fixed...

update:
I'm confused by this notice found in log. $GLOBALS should always exist, while it is one of the PHP predefined variables. I'm getting this error only in tests. If I try to test existence of the variable with isset($GLOBALS), it exists.

It's kind of strange.

PHP doesn't initialise $GLOBALS until referenced, so maybe your test harness/framework is analysing the symbols table and throwing the notice rather than PHP itself??

Honestly, I've no idea. I'm using PHPUnit 7.3.2 with convertNoticesToExceptions="true". All tests are green, I just get notices in error.log.

I'm not sure if I would get "PHP Notice: Undefined variable: GLOBALS in <path-to-project>\vendor\hfig\pear-ole\OLE\ChainedBlockStream.php on line 147" if test framework would be the source of the notice.
