I tried to connect to my database with mysqli_connect. this database is a remote MySQL database but my code gives the following error:
Warning: Packets out of order. Expected 0 received 1. Packet size=94 in ~\dashboard\config_app.php on line 16
Warning: mysqli_connect(): MySQL server has gone away in ~\dashboard\config_app.php on line 16
Warning: mysqli_connect(): Error while reading greeting packet. PID=14572 in ~\dashboard\config_app.php on line 16
Warning: mysqli_connect(): (HY000/2006): MySQL server has gone away in ~\dashboard\config_app.php on line 16
ERROR: Could not connect. MySQL server has gone away
The code:
<?php
define('DB_SERVER_app', 'server host name');
define('DB_USERNAME_app', 'username');
define('DB_PASSWORD_app', 'password');
define('DB_NAME_app', 'database name');
/* Attempt to connect to MySQL database */
$link_app = mysqli_connect(DB_SERVER_app, DB_USERNAME_app, DB_PASSWORD_app, DB_NAME_app);
?>
I'm sure the credentials aren't the problem.
Someone how knows what the problem is?
please help when I open http://localhost/phpmyadmin can't get in there and got a lot of error and I new in PHP my admin
problem :
mysqli::real_connect(): The server requested authentication method unknown to the client [sha256_password]

phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should 5. check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.
I'm trying to connect to an external database with php and I'm getting the "Packets out of order." error. I searched for it and I already changed the "max_allowed_packet" by query and by my.cnf, and both of which did not solve the problem.

I'm starting up a web server using Abyss X1, and just tried implementing a MySQL server through PHP with the following two scripts:
connect_db.php :
#Connect on 'localhost' for user 'admin'
#with password 'RoboticCowboy2019' to database 'site_db'.
$dbc = mysqli_connect
( 'localhost' , 'admin', 'password', 'site_db' )
OR die
( mysqli_connect_error() );
#Set encoding to match PHP script encoding.
mysqli_set_charset($dbc, 'utf8' );
and
require.php :
#Incorporate the MySQL connection script.
require ('../connect_db.php');
#Display MySQL version and host.
if(mysqli_ping($dbc)){
echo 'MySQL Server'.mysqli_get_server_info($dbc).'on'.mysqli_get_host_info($dbc);
}
However, when I go to http://localhost/require.php, I get these errors:
"Warning: mysqli_connect(): The server requested authentication method unknown to the client [caching_sha2_password] in /Applications/Abyss Web Server/connect_db.php on line 6"
"Warning: mysqli_connect(): (HY000/2054): The server requested authentication method unknown to the client in /Applications/Abyss Web Server/connect_db.php on line 6
The server requested authentication method unknown to the client"
I'm following the instructions of a book that I know is outdated, but I've been able to get around every problem until now. I've also read that it has something to do with MySQL updating and implementing sha2, while PHP still does not? I'm doing this for my compsci class, so I'd appreciate all the help I can get.
Thank you!
Alter the user
ALTER USER 'mysqluser'#'localhost' IDENTIFIED WITH mysql_native_password BY 'mysqlpassword';
or use
shell>mysql --default-auth=mysql_native_password
Okay when I go to my web page I get the following error below but when I reload the page everything is okay and is displayed fine. What exactly is the problem and how can I fix it?
ERROR.
Warning: mysqli_connect() [function.mysqli-connect]: (HY000/2005): Unknown MySQL server host
MySQL code.
$mysqli = mysqli_connect("example.com", "avd", "password", "avd");
Server/Port combination is invalid, can't be resolved, or port is bad.
