HomeBackend DevelopmentPHP Tutorial求救:mysql_fetch_row(): supplied argument is not a valid MySQL result resource

mysql_fetch_row


function db_connect() 
{
   $result = new mysqli('localhost', 'root', '654321', 'smsprj');
   //$result = new mysqli('localhost', 'root', '654321');
   if (!$result) 
   {
     throw new Exception('Could not connect to database server');
   } 
   else 
   {
     
     return $result;
   }
}

?>

$conn = db_connect();
$sql = $conn->query("SELECT * FROM user");

if (!$sql)

echo ("wrong");
}
else 
{
echo "";
echo "";
while( $row = mysql_fetch_row($sql) )
{
echo "";
}
}
我的目的是将数据库中的所有用户信息显示出来
可这段程序老是报错,不知道什么原因
求大侠帮助,小弟不胜感激

回复讨论(解决方案)

db_connect 中是这样的
   $result = new mysqli('localhost', 'root', '654321', 'smsprj');

所以要这样查询
$sql = $conn->query("SELECT * FROM user");

要这样读取
while( $row = $sql->fetch_row())

非常感谢,明天去公司试试。
被安排了根本不会的工作,真的是很让人蛋疼啊

What is a session in PHP, and why are they used?What is a session in PHP, and why are they used?May 04, 2025 am 12:12 AM

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
