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.
Changelog

It supports following parsing features:

• header section.
• msgid, both single and multiline.
• msgstr, both single and multiline.
• msgctxt (Message context).
• msgid_plural (plurals forms).
• #, keys (flags).
• # keys (translator comments).
• #. keys (Comments extracted from source code).
• #: keys (references).
• #| keys (previous strings), both single and multiline.
• #~ keys (old entries), both single and multiline.

composer require sepia/po-parser

<?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'));

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));
