Operating system: Irrelevant
PHP version:      Irrelevant
PHP Bug Type:     Documentation problem
Bug description:  Suggestion for Return Values description for isset()

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."
