Snip:

import os
import md5
for root,dirs,files in os.walk('/home/itorres/Media/Video/test'):
  for file in files:
    fp  = os.path.join(root,file)
    fp5 = md5.new(open(fp).read()).hexdigest()
    print "%s\n\t%s" % (fp,fp5,)

Boom! a quick inventory of my media with md5 checksum so I can search for duplicates based on it. For simplicity’s sake I made a database and metadata free version, only the directory walk, file read, md5 hash and print it.

Now, how does that look in php?

<?php
$dh = opendir('/home/itorres/Media/Video/test');
while (false !== ($file = readdir($dh))) {
    $fp = '/home/itorres/Media/Video/test' . '/' . $file;
    if(is_file($fp))
            echo "$fp\n\t" . md5_file($fp);
}
closedir($dh);

And how does it compare speed-wise? Notice that the php version does not walk the directory.
