I have used and tested the following:
$x = myFunction($someValue)? "true":"false";
When myFunction() returns an empty array, it results in false, and when
it returns a non-empty array it results in true. This is what I want
and expect, but I can''t find any documentation on it. Being naturally
cautious (spelled paranoid) I don''t want to rely on this until I''m
certain. Can anyone point me to the documentation that supports what
I''m seeing?解决方案x = myFunction(
