Perodicaly grab/refresh txt file?

dragon · 02-11-2007, 23:13

Anyone know Of a php script that can connect via http to a site and download a copy of a text file and display it, but if the original source file is not available display the last copy it was able to successfully download?

Also I'd like it to auto refresh every 30 seconds and show the time that the copy was cached.

Text file is http://dragon2611.dyndns.org/wpc.txt (link may not work, depends if the pc running it is turned on or not) I want it available to http://101st-wolfpack.net/catchup (currently a redirect) I want to cache it since the machine its produced by is my home "server" and I usually turn it off when its not in use.

The clan use the channel for their weekly meeting and sometimes people can't make it or join late so its purpose is for them to catch up on what's happened.

You can use the php shell command to call a wget if you want.

PHP you can set to enable http:// includes in the php.ini file if you have access

Surely that can be done via ini_set anyway...

Quite possibly, depends on the environment

I don't know how to code php, but I know someone who does and he's working on it for me

OK why don't you set up a CRON job to periodically grab the file and place it in the web directory, say in your home directory (for root or the web server user) put a file called "getfile.sh" and in it put something like

Code:

#!/bin/sh
cd /var/www/html
wget http://dragon2611.dyndns.org/wpc.txt

Log in as the root/web server user and type "crontab -e" (no quotes), assuming vi opens which is usually default, press i and then move to the last line (if there are any already and add)

5 * * * * ~/getfile.sh > /dev/null 2>&1

then press esc, and type :wq and press enter

then make sure the getfile.sh file is executable by typing chmod +x getfile.sh and Bob's your uncle, assuming everything is OK that file should be updated every hour of every day at five minutes passed.

I want it to update as soon as someone calls the page if the server is online.
