Po Parser


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

PoParser will allow you to read PO Data from any source (files and strings built-in), update it and store back to a file (or get the compiled string).

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 (previously untranslated), both single and multiline.
• #~ keys (old entries), both single and multiline.

Usage

// Parse a po file
$fileHandler = new Sepia\FileHandler('es.po');

$poParser = new Sepia\PoParser($fileHandler);
$entries  = $poParser->parse();
// $entries contains every entry in es.po file.

// Update entries
$msgid = 'Press this button to save';
$entries[$msgid]['msgstr'] = 'Pulsa este botón para guardar';
$poParser->setEntry($msgid, $entries[$msgid]);
// You can also change translator comments, code comments, flags...
