<?
# 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.";
# $_t["es"]["My cat is large."] = "Mi gato esta grande.";
#
# examples:
# print _("%s has %s apples.", array("Bill", "5"));
# print _("This is a %h%s%h problem!", array("<b>","major","</b>"));
include_once("common_po.inc");
function _($tag, $args=array()) {
global $_t;
global $_REQUEST;
global $LANG;
$supported_langs = array(
"en" => 1, # English
"es" => 1, # Español
"de" => 1, # Deutsch
"fr" => 1, # Français
);
# default to English if the lang hasn't been provided or isn't supported
#
$LANG = $_REQUEST['LANG'];
if (!$LANG || !array_key_exists($LANG, $supported_langs)) {
$LANG = "en";
}
# create the translation, if it doesn't exist, highlight it
#
$translated = $_t[$LANG][$tag];
if (!$translated) {
# if it's a supported language, but there isn't a translation,
# alert the visitor to the missing translation.
#
$translated = "<blink><b>_" . $tag . "_</b></blink>";
}
# replace escape substitutions
#
if (!empty($args)) {
while (list($k, $v) = each($args)) {
$translated = preg_replace("/\%[sh]/", $v, $translated, 1);
}
}
