mysql> SHOW VARIABLES LIKE 'character%';
+————————–+—————————-+
| Variable_name | Value |
+————————–+—————————-+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |

如果有不是utf8的更改my.ini 或my.cnf
[client]中添加
default-character-set=utf8
[mysqld]中添加
character-set-server=utf8
init_connect='SET NAMES utf8'
[mysql]中添加
default-character-set=utf8
然后重启mysql
如果需要临时生效, set 字段 = utf8 例如
set character_set_client = utf8
没用过老式的...下面两种你看看
如果用mysqli:
<code>mysqli::set_charset ( "utf8" ); </code>
如果用PDO,(推荐):
<code>$pdo = new PDO("mysql:host=localhost;dbname=test;charset=utf8", 'username', 'password'); </code>
<code>mysql_query("SET NAMES 'UTF8'"); </code>
try....
仅仅发现在数据库里面查看却发现了中文乱码,解决的办法有两步。
1、set names utf-8;
然后在select,看看是否已经正常,如果不正常,看第二步。
2、如果你是用secret CRT链接上服务器查看的话,那么设置一下当前配置字符集。【可选】
把mysql数据库的编码和php文件同时设置为相同的编码格式就可以了,一般用utf-8

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.

The article discusses PHP, detailing its full form, main uses in web development, comparison with Python and Java, and its ease of learning for beginners.

PHP handles form data using $\_POST and $\_GET superglobals, with security ensured through validation, sanitization, and secure database interactions.

The article compares PHP and ASP.NET, focusing on their suitability for large-scale web applications, performance differences, and security features. Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,

PHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.

The article discusses various methods for page redirection in PHP, focusing on the header() function and addressing common issues like "headers already sent" errors.
