RE: [PHP] Upload alert
What you're seeking is push technology. I'm not certain that PHP can provide that. However, PHP can email you using the mail() function -Original Message- From: Rodolfo Silva [mailto:[EMAIL PROTECTED]] Sent: Monday, April 08, 2002 12:16 PM To: [EMAIL PROTECTED] Subject: [PHP] Upload alert Hi!

I don't know where you can find it pre-made, but it's pretty simple. In a
nutshell:
$checksum = md5(implode('', file('http://www.whatever.org/')));
That'll give you a 32-character string.
Save $checksum in a database or in a local file.
Repeat as often as you need to (using cron or whatever). Compare the new
value against the one you saved. If they don't match, the page changed.
NB: This will catch ANY change in the page. If that page is set up to show
the current date, for instance, then that will be picked up as a change
every day. If you need to deal with something like this, you're going to
have to analyze and parse the page.

RE: [PHP] Upload alert
why couldnt you just do this
$checksum = md5(implode('', file('/path/to/file')));
then it would only warn you about change in the code pre-parse, rather than post-parse
as miguel suggested?

I assumed the web site was somewhere else; if it's on his own server,
wouldn't he already know that it was changed?
