I recommend using absolute paths in the $directory parameter. This caused me several hours to debug as Ajax calls to my localization functions messed up the path. And since no error if thrown if the path in $directory cannot be found, one should check the result always:

<?php
    // Imagine the path for this file is "/localization" and your locales are in the "/locale" directory.
    $pathToDomain = __DIR__ . "/../locale";
    if ($pathToDomain != bindtextdomain($domain, $pathToDomain)) {
        // Error handling.
    }
?>

The name of your .mo file must match the $domain, e.g. name your files messages.mo and call bindtextdomain("messages", $directory).
