That's actually a good point there that I can take away from this.
I actually don't have anything set to send me a log of code issues,
only when an error is caused (and, of course, anything server-related,
but that's a different point entirely).

Simple enough... put the following in a file, and add a cron job.

#!/usr/bin/php -qC
<?php

if( !isset( $argv[1] ) || !isset( $argv[2] ) || !isset( $argv[3] ) )
{
echo "Usage: {$argv[0]} <subject> <email> <path>\n";
exit( 1 );
}

$subject = $argv[1];
$email = $argv[2];
$path = $argv[3];

$content = implode( '', file( $path ) );

if( trim( $content ) === '' )
{
$content = 'NO ERRORS TODAY!!!';
}

mail( $email, $subject, $content );

?>

I used to have something similar to this until someone uploaded a script
that started writing to the error log like mad. Overnight my poor little
script tried to load a 240meg log file into memory and email it to me. I
now use a simple bash script that pipes the log to the mail command -
much safer.

Should probably say that it also renames the log file, graceful's
Apache, zips the old log and moves it to an archive file server. Rob's
script above, used without something that starts a new log will result
in ever-increasing emails.

Oh yeah, that's true-- totally forgot to wipe the error log. I just
whipped the above up :) I have something else on the server without
command line params that I wrote ages ago :) As for a huge file, unless
you set PHPs memory high it should just bail with a fatal memory
exhaustion error. A better script would gzip the log file and attach it
to an email.

Cheers,
Rob.

Wouldn't it even be a worthwhile idea to simply include the first
$n lines of the daily log in an email? That's how I have my logs
emailed to me for the server things. I receive the first 300 lines of
the file, and if there's more than that (which, for server logs, there
always are, because I monitor everything), then I know to either hop
on the server and `vim` the log or download it and read it.

In any case, rotating and archiving would be a requirement.
Depending on the log, mine generally rotate daily or once every three
days, with backups being maintained for at least 30 days.
