DirectorySync is a directory synchronizing and backup utility providing automated, real-time syncing and scheduled, configurable backups at an affordable price.

How to fix: Warning: Invalid argument supplied for foreach()

This warning happens only if you try to use foreach on a non array like:

$myvar = 10;
foreach ($myvar as $value) {}

If you run this, you will get:

Warning: Invalid argument supplied for foreach() in YOUR_FILE on line FOREACH_LINE

To fix this just cast $myvar to array like this:

$myvar = 10;
foreach ((array) $myvar as $value) {}
