The first, HTML and PHP mixed page solution
Method 1: Use tag
If it is embedded in HTML PHP code, you can use <meta charset="UTF-8"> to solve the Chinese garbled problem
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>php输出中文乱码</title> </head> <body> <div class="demo"> <?php echo "php中文网！"; ?> </div> </body> </html>
Method 2: Use the header() function
How to mix HTML and PHP, in addition to following the operations mentioned in the first method, 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
?>The second type is the problem of Chinese garbled characters in pure PHP pages (the data is static)
If your PHP page has garbled characters, you only need to add the following code at the beginning of the page.
<?php
header("content-type:text/html;charset=utf-8"); //设置编码
?>The third type, PHP Mysql Chinese garbled problem
In addition to following the third operation, you also need to Add database encoding before querying/modifying/adding your data. 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('SET NAMES UTF8');
//接下来的就是查出数据或者修改，增加
?>If you are using MySQL version 4.1 or higher, you can set a character encoding after the link database operation, like the following
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, it is mainly used in Chinese website development. There are two encodings: GB2312 and UTF-8.
One thing to note is that 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 mysql The 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

How does using HTTPS affect session security?Apr 22, 2025 pm 05:13 PMHTTPS significantly improves the security of sessions by encrypting data transmission, preventing man-in-the-middle attacks and providing authentication. 1) Encrypted data transmission: HTTPS uses SSL/TLS protocol to encrypt data to ensure that the data is not stolen or tampered during transmission. 2) Prevent man-in-the-middle attacks: Through the SSL/TLS handshake process, the client verifies the server certificate to ensure the connection legitimacy. 3) Provide authentication: HTTPS ensures that the connection is a legitimate server and protects data integrity and confidentiality.
