php check function

[Daniel]

Hello all,

I want to have a PHP script to open a popup on the right bottom of the
screen(like hotmail or yahoo).
I want to write a function that checkes every 10 seconds, if there are new
messenges from an Mysql database ,
if CurrCount < NewCount , the check will be made.
Can anyone point me in the right direction?


Thanks in advance

Danny

Re: php check function

What you're looking for will require AJAX, assuming you don't want to
refresh a page every 10 seconds to formulate a new request. You cannot
do this in php alone, as php is server side.

How can you do this with AJAX without perform a (XMLHTTP) request every
10 seconds? Btw, have you tried conditional get with XMLHTTP already? In
my experience it doesn't work well...

Performing an XMLHTTP request and reloading the page are different things.
In the first case user doesn't need to know that the page is being
reloaded: he can read contents and fill forms normally.

But of course that's JavaScript and it's offtopic ;-P

interesting info)


Another typical option is using an iframe. I guess he's writing a chat so
it can be a solution.
