<?php
/**
* Changes from php.mo:
* supress the error if there's no file
* fixed "fuzzy flag first line" bug which didn't saved previous proper string at all
* fix the warning if list finds no $data
* added case for commented unused string
* proper handling of msgctxt
* better storing of same msgid
* corrected data structure for correct counting of plural msgstr
* don't add last translation if it's fuzzy
* removed unedeed phpmo_convert and phpmo_write_mo_file
* more info on https://bugs.mageia.org/show_bug.cgi?id=14899
* added option for passing translation directly as an array
* changed structure of resulting array
*
* it returns array of translations:
* $dictionary = phpmo_parse_po_file('input.po');
*
* $dictionary = array (
* '' => array (
* 0 => array (
* 0 => 'Project-Id-Version: ...',
* ),
* ),
* 'msgid string for translation 1' => array ( // msgid
* 0 => array (
* 0 => 'translated string 1', // msgstr
* ),
* ),
* 'msgid string for translation 2' => array ( // msgid
* 0 => array (
* 0 => 'translated string 2', // msgstr
* ),
* 'context explanation for msgstr[1]' => array ( // msgctxt
* 0 => 'translated string 2 but different context', // msgstr
* ),
* 'context explanation for msgstr[2]' => array ( // msgctxt
* 0 => 'another translated string 2 with different context', // msgstr
* ),
* ),
* 'msgid string for translation 3' => array ( // msgid
* 0 => array (
* 'msgid_plural' => 'plural string for translation 3', // msgid_plural
* 0 => 'translated string 3 for nplurals 0', // msgstr[0]
* 1 => 'translated string 3 for nplurals 1', // msgstr[1]
* 2 => 'translated string 3 for nplurals 2', // msgstr[2]
* ),
* ),
* 'msgid string for translation 4' => array ( // msgid
* 'context explanation for msgstr[0]' => array ( // msgctxt
* 'msgid_plural' => 'plural string for translation 4', // msgid_plural
* 0 => 'translated string 4 for nplurals 0', // msgstr[0]
* 1 => 'translated string 4 for nplurals 1', // msgstr[1]
