php调用mysql存储过程问题
为什么我调用一次存储过程后再做其他查询后就错误了呢?
-------------------------
我要php调用mysql存储过程来查询表中所有数据,正常得出结果.
紧接着做其他查询时,不管使用什么语句都返回错误.
这是存储过程:
#查询shares表中的数据
#call proc_show_shares('sendtime'); //排序对象
delimiter //
DROP PROCEDURE IF EXISTS proc_show_shares //
CREATE PROCEDURE proc_show_shares (in sorttype varchar(15))
BEGIN
Set @sql = concat("select* from shares order by ", sorttype," desc");
PREPARE cmd from @sql;
EXECUTEcmd;
DEALLOCATEPREPARE cmd;
END//
delimiter ;
以下代码运行正常:
$query = "call proc_show_shares('sendtime')";
$results = mysql_query($query); //调用存储过程
while($result_row = mysql_fetch_row($results))
{
//{代码段}
$values[] = $result_row;
}
其中{代码段}是被注释掉的.当取消注释时,就错误了.
代码段为:
$result = mysql_query("select name from users where id = 10001") or die('靠');
上面的sql语句单独运行正常(当然是有结果的),连在一起就输出'靠'了.
为什么?
我可以输出values,但是加上mysql_query("select name from users where id = 10001") or die('靠');就不行了.然而这条语句本身是正确的.
所有过程中数据库一直是连接状态的.

Effective methods to prevent session fixed attacks include: 1. Regenerate the session ID after the user logs in; 2. Use a secure session ID generation algorithm; 3. Implement the session timeout mechanism; 4. Encrypt session data using HTTPS. These measures can ensure that the application is indestructible when facing session fixed attacks.

Implementing session-free authentication can be achieved by using JSONWebTokens (JWT), a token-based authentication system where all necessary information is stored in the token without server-side session storage. 1) Use JWT to generate and verify tokens, 2) Ensure that HTTPS is used to prevent tokens from being intercepted, 3) Securely store tokens on the client side, 4) Verify tokens on the server side to prevent tampering, 5) Implement token revocation mechanisms, such as using short-term access tokens and long-term refresh tokens.

The security risks of PHP sessions mainly include session hijacking, session fixation, session prediction and session poisoning. 1. Session hijacking can be prevented by using HTTPS and protecting cookies. 2. Session fixation can be avoided by regenerating the session ID before the user logs in. 3. Session prediction needs to ensure the randomness and unpredictability of session IDs. 4. Session poisoning can be prevented by verifying and filtering session data.

To destroy a PHP session, you need to start the session first, then clear the data and destroy the session file. 1. Use session_start() to start the session. 2. Use session_unset() to clear the session data. 3. Finally, use session_destroy() to destroy the session file to ensure data security and resource release.

How to change the default session saving path of PHP? It can be achieved through the following steps: use session_save_path('/var/www/sessions');session_start(); in PHP scripts to set the session saving path. Set session.save_path="/var/www/sessions" in the php.ini file to change the session saving path globally. Use Memcached or Redis to store session data, such as ini_set('session.save_handler','memcached'); ini_set(

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.
