Dear All,
I was reading the php manual for session_register, and I found the following
line there : -
$_SESSION[$var] = $$var;
Why do I need $$ there ? Can someone explain?
Thank you,

Hi Ashim,
These are called Variable Variables. Ideally they should be avoided,
as they introduce unnecessary legibility issues.
This is what it does in a nutshell, it's actually quite simple:
$foo = 'bar';
$bar = 'foobar';
echo $$foo;//This prints foobar
What it does is, take the
It doesn't though, it creates a copy of the $_GLOBALS super global array,
removes entries that will have been set by the system (i.e. it leaves
user-defined variables) and then returns the ones that are left, so in that,
the user note is perfectly correct.
What has me puzzled is how unsetting
Unsetting doesn't leave user defined variables. Unsetting simply destroys
variables (or removes elements from an array, etc). There is nothing magic
or hidden in that script. I think the note meant exactly what it said: after
creating a local copy of the $GLOBALS array and removing super
I'll remove it.
How does one remove user notes from php.net ?
Thank you,
Ashim
Dear Ashley,
I do follow the part when it creates a local copy of $GLOBALS.
When it unsets them, is there a subtlety of unset that it ONLY unsets system
defined entries? Could you please explain this ?
Thank you,
Ashim

The quotes you mention are in the HTML, nothing to do with PHP. HTML will
work without the quotes in most cases (unless there's a space in the value
for the attribute) but the quotes are required in XHTML and will cause
unexpected results.
Can you elaborate on the XHTML part? Do you mean they are
Yes, in HTML the quotes are optional, but they are required in XHTML
documents:
