Subject: variable_exists() patch
From: torben@php.net (Lars Torben Wilson)

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.


Thanks,

Torben
