Hi out there, A few weeks ago I submitted a patch in the bug db for a variable_exists() construct, which parallels the function_exists() one but for variables. In short, it returns TRUE if a variable exists, regardless of its value. In other words, it's an isset() which doesn't care if the variable's value is NULL.
The bug report and a link to the patch is here: http://bugs.php.net/bug.php?id=24274&edit=1 Just mentioning it because I don't know whether it's good enough to go in, but users have emailed me to ask why it hasn't been included. If I've screwed up with the patch, a quick note as to what was wrong would be great.
