What should I do if a garbled window pops up when executing the alert() function in the PHP page?

Problem description:

The encoding method of the PHP page is utf-8. When the following code is output, a garbled window pops up.

echo "<script type=&#39;text/javascript&#39;>alert(&#39;已全部清除!&#39;);script>";

Solution:

Because alert() outputs Chinese to the browser, you must specify the encoding method as UTF-8 in the web page, that is,

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

Note: If the PHP page encoding method is gb2312, there is no need to add

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
