I've found that, at least in the PHP version I'm using, setting a variable to true (i.e.
"$var = true;"), then passing it to a function (i.e. "Test($var);"), will cause
the passed variable within that method to be considered null/nully (i.e. "if ($var !=
null)" returns false), even if from within the calling function it is not considered
null/nully. (i.e. "if ($var != null)" returns true)
In other words, passing a true boolean variable to a function will turn it into a null/nully value,
within the function.
To me this seems extremely odd, and backwards, behavior.
If a variable is "!= null" in the caller function, it should be "!= null" in the
called function.
(Note: My PHP version is 5.4.3)
