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

Second: HTML and PHP mixed page solution

How to mix HTML and PHP, in addition to following the operations mentioned in the first method In addition, you also need to add this code at the top of the PHP file:

<?php
header("content-type:text/html;charset=utf-8");         //设置编码
?>

<?php
header("content-type:text/html;charset=utf-8");         //设置编码
?>

The fourth type: PHP Mysql Chinese garbled problem

In addition to following the operations mentioned in the third type, you also need to query/modify your data /Add database encoding before adding. Moreover, it is worth noting that the UTF8 here is different from the previous one, there is no horizontal line in the middle.

<?php
   mysql_query(&#39;SET NAMES UTF8&#39;);
   //接下来的就是查出数据或者修改，增加
?>

UTF-8 encoding is just one of the encodings. If you don’t want to use utf-8 encoding, you can also use other encodings. Just replace UTF-8 with the encoding you want to use. Currently, the main one used in Chinese website development is GB2312 and UTF-8 two encodings.

Note:

The mysql_query("set names 'coding'"); encoding added before the PHP program that needs to perform database operations must be consistent with the PHP encoding. , if the php encoding is gb2312, then the mysql encoding is gb2312, if it is utf-8, then the mysql encoding is utf8, so that there will be no garbled characters when inserting or retrieving data.
