If you want to change the text after it has been downloaded by the client (for example, have the text change every five seconds or something), you must use javascript. PHP is only used for server-side generation of the markup that the client downloads.
如果要在客户端下载文本后更改文本（例如，每 5 秒更改一次文本或其他内容），则必须使用 javascript。PHP 仅用于服务器端生成客户端下载的标记。

<textarea rows="2" cols="20">
<?php echo "Your text here. This can be dynamically created with PHP
when the page is served."; ?>
</textarea>
So, the textarea can be filled with PHP, but if you want to change the textarea after the page has loaded.... once it's out of the hands of the server, then you have to use Javascript.
所以，textarea可以用PHP填充，但是如果你想在页面加载后改变textarea....一旦它脱离了服务器的控制，那么你必须使用Javascript。

<td>
<textarea rows="4" cols="10">
<?php
echo $row['baddress'] ;
?>
</textarea>
</td>
<?php
echo $row['baddress'];
?>
It must be call separately here baddress is the column name of my data base
必须单独调用这里 baddress 是我的数据库的列名
