I18n with gettext
1. Install gettext2. Make sure php has gettext support
3. Create a directory structure like the following:
test.php locale en_US LC_MESSAGES zh_TW LC_MESSAGES
Test.php should look like this
<?php
header('Content-Type: text/html; charset=utf-8');
if (isset($_GET['lang'])) {
$language = $_GET['lang'];
} else {
$language = "en_EN";
}
$locale = setlocale(LC_ALL, $language);
$gettext_domain = 'messages';
bindtextdomain($gettext_domain, "./locale");
textdomain($gettext_domain);
?>
<html>
<head>
<meta http-equiv="Content-Type" Content="text/html; charset=utf-8">
</head>
<body><form id="form1" name="form1" method="get">
<input type=radio name="lang" id="lang" value="en_EN" onchange="document.form1.submit();"><? echo gettext("English"); ?>
<br>
<input type=radio name="lang" id="lang" value="zh_TW" onchange="document.form1.submit();"><? echo gettext("Chinese"); ?>
<br>
</form>
<h1><? echo _("English"); ?></h1>
</body>
</html>
header('Content-Type: text/html; charset=utf-8');
if (isset($_GET['lang'])) {
$language = $_GET['lang'];
} else {
$language = "en_EN";
}
$locale = setlocale(LC_ALL, $language);
$gettext_domain = 'messages';
bindtextdomain($gettext_domain, "./locale");
textdomain($gettext_domain);
?>
<html>
<head>
<meta http-equiv="Content-Type" Content="text/html; charset=utf-8">
</head>
<body><form id="form1" name="form1" method="get">
<input type=radio name="lang" id="lang" value="en_EN" onchange="document.form1.submit();"><? echo gettext("English"); ?>
<br>
<input type=radio name="lang" id="lang" value="zh_TW" onchange="document.form1.submit();"><? echo gettext("Chinese"); ?>
<br>
</form>
<h1><? echo _("English"); ?></h1>
</body>
</html>
