well basically I am writing a simple routing script. It reads data
from an XML and from a PostgreSQL.
Some of the data is being randomized, and every now and then some data
is echoed in the background.
Is there a way to have the script, using XMLHTTPResponse (AJAX), to
make this :
- Run the script in the background
- Whenever the script echo's soemthing it echoes to the main <div> I
want it to
- The new echo should replace the prior echo
- The echo should be real time / live
user one by one
The script which echo's data is already done via PHP and can be
accessed here : http://yancho.no-ip.org/~yancho/xml_parser.php
As you can see it echo's randomly (basically before reading each XML
edge, it waits 10 seconds, but then, since sometimes it compares and
fails, and has to compare again, it waits another 2 seconds.
be done on the PHP script.
On my php script, at the moment I am using this : http://yancho.pastebin.com/f4b4b4b11
Any suggestions on which AJAX methods I need to read into and which
PHP alterations are needed will extremely help me please.
Re: Echoing from a Script
conventional web techniques are based on client pull. If there's a
real non-exotic implementation of that it's news to me. The belief
that AJAX provides it is a common error, IMO.
Google for that phrase and you'll see what I mean.
