我有一个房地产脚本，它包含一个用于翻译的语言环境文件，我翻译了它，但文本显示为问号......尝试了以下但没有成功
添加
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">头部元素添加
AddDefaultCharset utf-8到 .htaccess- 添加
AddDefaultCharset utf-8到 httpd.ini 将此行添加到 php.ini
default_charset = "utf-8"mbstring.internal_encoding=utf-8mbstring.http_output=UTF-8mbstring.encoding_translation=Onmbstring.func_overload=6
以下是一些脚本页面：
index.php（控制面板，这里翻译的文字也是乱码）
<?php
ob_start();
?>
<!doctype html>
<html>
<head>
<title>Property Listing</title>
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
</head>
<body>
{APP_TPL}
</body>
</html>
<?php include 'listings.php'; ?>
清单.php
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<?php
if (!isset($_GET['iframe']))
{
$content = ob_get_contents();
ob_end_clean();
ob_start();
}
if (!isset($_GET['controller']) || empty($_GET['controller']))
{
$_GET["controller"] = "Listings";
}
if (!isset($_GET['action']) || empty($_GET['action']))
{
$_GET["action"] = "index"
include dirname(__FILE__) . '/index.php';
if (!isset($_GET['iframe']))
{
$app = ob_get_contents();
ob_end_clean();
$app = str_replace('$','$',$app);
echo preg_replace('/\{APP_TPL\}/', $app, $content);
}
?>
