<?php
# this include file provides support for i18n
#
# usage:
# use the __() function for returning translated strings of
# text. The string can contain escape codes %h for HTML
# and %s for regular text.
#
# supporting scripts:
# there is a supporting script, web/utils/genpopo, that will
# parse the PHP files and create PHP include files that contain
# a mapping for each translated language. The include files
# have the form,
#
# $_t["en"]["My cat is large."] = "My cat is large.";
# $_t["es"]["My cat is large."] = "Mi gato esta grande.";
#
# examples:
# print __("%s has %s apples.", "Bill", "5");
# print __("This is a %h%s%h problem!", "<b>","major","</b>");
#
# deprecated usage:
# print __("%s has %s apples.", array("Bill", "5"));
include_once("common_po.inc");
function __() {
global $_t;
global $LANG;
# create the translation, if it doesn't exist, highlight it
#
$args = func_get_args();
# First argument is always string to be translated
$tag = $args[0];
if (empty($LANG) || $LANG == DEFAULT_LANG)
$translated = $tag;
else
$translated = $_t[$LANG][$tag];
if (empty($translated)) {
# if it's a supported language, but there isn't a translation,
# alert the visitor to the missing translation.
#
$translated = "_${tag}_";
}
$translated = htmlspecialchars($translated, ENT_QUOTES);
# This condition is to reorganise the arguments in case of
# deprecated usage. __("string", array("string","string"))
if (!empty($args[1]) && is_array($args[1])) {
array_unshift($args[1], $tag);
$args = $args[1];
}
$num_args = sizeof($args);
# Subsequent arguments are strings to be formatted
if ( $num_args > 1 ) {

$translated = preg_replace("/\%[sh]/", $args[$i], $translated, 1);
