.. _php2po#examples:

Examples
========
This example looks at roundtrip of PHP translations as well as recovery of
existing translations.

First we need to create a set of POT files.::

  php2po -P lang/en pot/

All .php files found in the ``lang/en`` directory are converted to Gettext POT
files and placed in the ``pot`` directory.

If you are translating for the first time then you can skip the next step. If
you need to recover your existing translations then we do the following::

  php2po -t lang/en lang/zu po-zu/

Using the English PHP files found in ``lang/en`` and your existing Zulu
translation in ``lang/zu`` we create a set of PO files in ``po-zu``.  These
will now have your translations. Please be aware that in order for that to work
100% you need to have both English and Zulu at the same revision, if they are
not you will have to review all translations.

You are now in a position to translate your recovered translations or your new
POT files.

Once translated you can convert back as follows::

  po2php -t lang/en po-zu/ lang/zu

Your translations found in the Zulu PO directory, ``po-zu``, will be converted
to PHP using the files in ``lang/en`` as templates and placing your new
translations in ``lang/zu``.

To update your translations simply redo the POT creation step and make use of
:doc:`pot2po` to bring your translation up-to-date.
