Problems with zmprov in a cron

[Dunhamzzz]

I have written a script which contacts another server, downloads (PHP + curl) a list of Zmprov commands and then carries out a PHP exec() to commands to zmprov. After that it pings another file on the remote server to tell the remote server it is complete. This works absolutely fine when I run it with

php -f /path/to/fetch_commands.zmp

However when I put it in the zimbra users crontab, for some reason the zmprov part fails with no error.

Here is the script:

<?php
$sourceUrl = 'https://secure.domain.com/tools/zimbra.zmp';
$dumpPath = '/tmp/zimbra-commands.zmp';

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $sourceUrl);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_USERPWD, 'user:pass');
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);

echo "Fetching Commands...\r\n";
$result = curl_exec($ch);

// Only write to file if needed
if(strlen($result) > 0) {
	
	$fp = fopen($dumpPath, 'a');
	fwrite($fp, $result);
	fclose($fp);
	
	// Now we've written the commands, we need to push them to zmprov
	echo "Setting up accounts..";
	exec("zmprov < /tmp/zimbra-commands.zmp"); // This is FAILING when ran from a cron
	
	// Delete them as we don't need to do them again.
	unlink($dumpPath);

	// Now we need to ask the server to clear out the commands
	curl_setopt($ch, CURLOPT_URL, 'https://secure.domain.com/tools/zimbra-post-update.php');
	curl_exec($ch);
}

curl_close($ch);

Here is the cronjob and how I set it up:

sudo su zimbra
crontab -e

*/10 * * * * php -f /tmp/fetch_commands.php

The PHP script definitely runs, as it contacts my post-update file on my server and it's logged.

I don't use PHP scripts myself, but are there missing environment variables which may be included when running as the Zimbra user (some of what is in .bashrc or .bash_profile) but not when running the cronjobs (which I think run in sh, not bash)?

Yeah I resolved it, the problem was the path to zmprov, I needed the entire absolute path to it. It also didn't help I was logging the cron errors properly!
