Auto check and email reply with PHP

[LemonHead]

I wish to check my site automatically every day at some hour like 11 pm and then perform a check such as

If memeber posted a message or picture then
send email with link to all memebers
else
die
end if

I know how to send an email using php, but is there any script available that would automatically start on my server (my site is hosted by Yahoo) at a certain time and perform the above check ?

Or do I need to make my wife turn on my computer at 11 each night and set some type of batch job on my local PC to open my web site at emailcheck.php and run the php code, etc..

If your host is a UNIX/Linux server and they allow cron jobs you can setup a job to run a php file from command line at a certain time.

Another possiblity is if you can modify the code that allows users to add messages/photos that after it writes the data to a database or uploads the photo it sends an email to all the required people notifying them. This would be more real-time and you wouldn't have to worry about your script kicking off to run this.

I thought about creating te script after each message, picture, etc. However, if there are 15 messages created in a day thats 15 messages. I need to compact things to once a day. Within one email there would be 15 links linking each message for that day.
