imap_search ?
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,
Ashim
hi ! it works if there is / are emails in the box before script run (i use
cli not web based) but after it works 1 time it doesnt work again it enters
to infinite loop ,
at that line
while(!$emails) { $emails = imap_search($inbox,'ALL'); echo email yok\n;
print_r($emails); }
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 value of

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
Just being curious, I have a question.
How many times PHP interpreter will replace this variables? I mean how deep
it will be?
If I use variable variables like
$$a
how long it will be evaluated?

Ashim:
You don't need to user session_register().
If $a = 'foo'
and $$a = nothing (i.e. no value assigned to $foo) you will get an error if
you tried to use this to do something else.

i'm not sure i understand your problem ?!?
php runs on the server, delivers html code and/or javascript to the browser
and only from there the jQuery will execute it's main loop and start trigger
some events such as the ready event. So the php script is always finish
when javascript start to
Also, the $(document).ready() is triggered when the DOM is ready to be
manipulated.
I dont know why you would consider alter the behavior of this event, maybe
what you want is to create yourself a custom event handler ...

Is anyone else out there in the same boat?
Actually we have found the complete opposite so there might be some
people who are in the same boat as you but certainly not all.

As per my experience so far, there is no such depth limit existing. The only
limit is imposed by the system resources (like script execution time etc.)
but not by PHP.
