PHP script that sends an email listing file changes that have happened in a directory/subdirectories

I have a directory with a number of subdirectories that users add files to via FTP. I'm trying to develop a php script (which I will run as a cron job) that will check the directory and its subdirectories for any changes in the files, file sizes or date开发者_高级运维s modified. I've searched long and hard and have so far only found one script that works, which I've tried to modify - original located here - however it only seems to send the first email notification showing me what is listed in the directories. It also creates a text file of the directory and subdirectory contents, but when the script runs a second time it seems to fall over, and I get an email with no contents.

Anyone out there know a simple way of doing this in php? The script I found is pretty complex and I've tried for hours to debug it with no success.

Thanks in advance!

Here you go:

$log = '/path/to/your/log.js';
$path = '/path/to/your/dir/with/files/';
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
$result = array();

foreach ($files as $file)
{
    if (is_file($file = strval($file)) === true)
    {
        $result[$file] = sprintf('%u|%u', filesize($file), filemtime($file));
    }
}

if (is_file($log) !== true)
{
    file_put_contents($log, json_encode($result), LOCK_EX);
}

// are there any differences?
if (count($diff = array_diff($result, json_decode(file_get_contents($log), true))) > 0)
{
    // send email with mail(), SwiftMailer, PHPMailer, ...
    $email = 'The following files have changed:' . "\n" . implode("\n", array_keys($diff));

    // update the log file with the new file info
    file_put_contents($log, json_encode($result), LOCK_EX);
}

I am assuming you know how to send an e-mail. Also, please keep in mind that the $log file should be kept outside the $path you want to monitor, for obvious reasons of course.

After reading your question a second time, I noticed that you mentioned you want to check if the files change, I'm only doing this check with the size and date of modification, if you really want to check if the file contents are different I suggest you use a hash of the file, so this:

$result[$file] = sprintf('%u|%u', filesize($file), filemtime($file));

$result[$file] = sprintf('%u|%u|%s', filesize($file), filemtime($file), md5_file($file));
// or
$result[$file] = sprintf('%u|%u|%s', filesize($file), filemtime($file), sha1_file($file));

But bare in mind that this will be much more expensive since the hash functions have to open and read all the contents of your 1-5 MB CSV files.

I like sfFinder so much that I wrote my own adaption:

http://www.symfony-project.org/cookbook/1_0/en/finder

https://github.com/homer6/altumo/blob/master/source/php/Utils/Finder.php

Simple to use, works well.

However, for your use, depending on the size of the files, I'd put everything in a git repository. It's easy to track then.
