Thanks in advance for your feedback.

In my php.ini file I have below

Hi sabecs,

You can read this article on how to write a crontab entry: How to setup a crontab job in Linux / Unix

Do you already have a script that is sending the email and doing the cleanup? If so then you can add that script to the crontab. If you don't have a script yet, how can we help you with that?
I don't know how to send the email with php, but you can do it with bash.

Send the file to yourself:
mail -s "LOG FILE" < /var/log/phpmail.log

Clear the log file:
cat /dev/null > /var/log/phpmail.log

Thanks for your feedback, much appreciated.
I don't have a script yet. Just wondering on where I would need to set it up?
Can I run from a users cPanel account, would there be access issues or do I setup in WHM.
I do have root access to my VPS?

I don't know if you have root access. You will have to ask your hosting company. You will need root to access the logs in any way.

Hi, Savone's suggestion 'mail -s "LOG FILE" < /var/log/phpmail.log' works great from the command line , but how can I automate to run once a weekly?
If you want it to run once a week, put it in a cron job.

type the following command to edit crontab:

crontab -e

It will open in your default editor, usually vi.  If you don't know how to use vi, let me know.

Add the following line to the file:

* * * * 0 mail -s "LOG FILE" < /var/log/phpmail.log

This will run the job once a week on Sunday.

Thanks Savone, much appreciated.
I have downloaded the file root from /var/spool/cron, can I just edit it with editplus or notepad and then uploaded the file instead of using vi?

Also can I append cat /dev/null > /var/log/phpmail.log to existing command to clear file after its emailed like below?

* * * * 0 mail -s "LOG FILE" < /var/log/phpmail.log && cat /dev/null > /var/log/phpmail.log

About sending email with php it's quite simple. Just use the mail() function.
Here you have an example:

		$name = "John Foo";
		$email = "";
		$message = "Hello world";
		$to = '';
		$subject = 'A new message';
		$headers = "From: " . strip_tags($email) . "\r\n";
		$headers .= "Reply-To: ". strip_tags($email) . "\r\n";
		$headers .= "MIME-Version: 1.0\r\n";
		$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
		if (mail($to, $subject, $message, $headers))
			echo 'Message sent';
			echo 'Ooops!';

Yes, you can do both, so basically add the following:

* * * * 0 mail -s "LOG FILE" < /var/log/phpmail.log; cat /dev/null >> /var/log/phpmail.log

@sabecs: was this question even about how to sen an email with php or was it just about to use cron to delete a log file? I'm missing something...

Hi Marco, I didn't know that you could send the email with just a cron job only, so no need complicate things by adding php as well.  Thanks
