我写了一些代码来帮助我工作，这会将文本的字符串/斑点转换为可以用作元数据的东西。
我写了以下内容，但只还原作品...我对PHP很陌生，所以对我来说这令人困惑！
<?php
$text = $_POST['field'];
if(isset($_POST['convert'])){
$trans = array("&" => "&", "'"" => """, "“" => """, "”" => """, "'" => "'", "<" => "<", ">" => ">");
} else if(isset($_POST['revert'])){
$trans = array("&" => "&", """ => "'"", "'" => "'", "<" => "<", ">" => ">");
}
?>

</tr>
</table>

我在我在这里创建的网站上有一个现场演示：www.gentetcreations.co.uk/metaConvert.php
您的代码实际上可以工作，但您必须对"未编码"文本进行 HTML 编码以"按原样"显示它。试试这个：
<?php echo htmlspecialchars(strtr($text, $trans)); ?>
htmlspecialchars(( 执行此转换
