PoParser

PoParser is a personal project to fulfill a need I got: parse Gettext Portable files (*.po files) and edit its content using PHP.

PoParser requires PHP >= 5.4, but may work in 5.3 too.

Installation

Usage

<?php 
// Parse a po file
$fileHandler = new Sepia\PoParser\SourceHandler\FileSystem('es.po');

$poParser = new Sepia\PoParser\Parser($fileHandler);
$catalog  = $poParser->parse();

// Get an entry
$entry = $catalog->getEntry('welcome.user');

// Update entry
$entry = new Entry('welcome.user', 'Welcome User!');
$catalog->setEntry($entry);

// You can also modify other entry attributes as translator comments, code comments, flags...
$entry->setTranslatorComments(array('This is shown whenever a new user registers in the website'));
$entry->setFlags(array('fuzzy', 'php-code'));

Save Changes back to a file

Use PoCompiler together with FileSystem to save a catalog back to a file:

$fileHandler = new Sepia\PoParser\SourceHandler\FileSystem('en.po');
$compiler = new Sepia\PoParser\PoCompiler();
$fileHandler->save($compiler->compile($catalog));
