From manual page: https://php.net/function.getopt

ON the manual page for getopt it states:

> This function will return an array of option / argument pairs, or false on failure.

When there are no options, it returns an empty array.  

So my bug report is to suggest that you indicate that "false on failure" refers to some other kind of failure and that no options found is indicated by an empty array. 

Thanks


Test script:
---------------
$options = getopt('', ['help', 'limit:', 'loops:', 'endtime:', 'tomorrow', 'agency:']);

Expected result:
----------------
Based on the doc, if I call the script with no options, I expected failure. 

Actual result:
--------------
I got an empty array.  

Note that I'm quite happy with the empty array, but wish that things in the doc had been a bit less ambiguous.
