Description:
------------
The documentation for isset() currently describes the Return Values as:

"Returns TRUE if var exists; FALSE otherwise."

I would propose that it be changed to:

"Returns TRUE if var exists and has a non-NULL value; FALSE otherwise."

That's the same issue already stated by bug #47032, although your suggestion may be of more practical use for people that maintain the doc. The two bug should then be merged in some way.

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.
