I have an .exe setup to run every 5 minutes.It creates a file.

I have stored the users email in a mysql database. The file that get created is named after the primary key of the database.For example:

1.txt,2.txt,50.txt etc

Where 1,2,and 50 are the primary keys.

I was wondering if there was a way after the cron ran to email the users.I use php on my server.Is there some way to do this?

EDIT:
I think I can rather just set up a .php file to run on cron and use exec().

    In your crontab, you can have cron entries and you can have environment variables. There is a variable called MAILTO that specifies the user that will receive the email containing any stdout or stderr from the processed jobs.
    To send email to vivek@nixcraft.in, enter:

    MAILTO=vivek@nixcraft.in

    If MAILTO is defined but empty (MAILTO=””), no mail will be sent.

    MAILTO=""

    The default (if MAILTO is not set) is to email the local user who owns the crontab being executed.

    I haven’t tried it, but you may be able to set the email for just one of your cronjobs using something like this:

    0 0 * * * /root/daily_task.sh #will email crontab owner
MAILTO=joe@gmail.com
0 1 * * * /root/other_daily_task.sh # will email joe@gmail
MAILTO=root
0 * * * * /root/hourly_task.sh #(hopefully) mails root and not joe

    Anything after a # on a line is of course a comment.
