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.
Warning: Packets out of order. Expected 0 received 45. Packet

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?
Hai iam using phpmyadmin for a long time. now i want to change to mysql workbench. so i start with basics How can i connect my db.

correct me if i am wrong.. Thanks
I've read many questions similar to this but none of the answers have been relevant to me. I'm trying to access a SQL server using PHP. Both the SQL server and PHP are running on my Windows 10 machine. Here is my PHP code (the username and password are arbitrary):
$connection = mysqli_connect('127.0.0.1', 'hmuuser', 'password');
This causes the following error:
PHP Warning: mysqli_connect(): (HY000/2002): No connection could be made because the target machine actively refused it.
Here is my connection using MSSMS (which is successful):
EDIT:
I was able to solve my problem using this link: http://blog.citrix24.com/configure-sql-express-to-accept-remote-connections/
Using this link I enable SQL Browser, and set a static port to connect to SQL server with. However, I'm presented with a new error:
PHP Warning: mysqli_connect(): MySQL server has gone away in C:\HMUAPI\Index.php on line 7
PHP Warning: mysqli_connect(): Error while reading greeting packet. PID=9920 in C:\HMUAPI\Index.php on line 7
PHP Warning: mysqli_connect(): (HY000/2006): MySQL server has gone away in C:\HMUAPI\Index.php on line 7
My code has been changed to the following to cause this error: $connection = mysqli_connect('127.0.0.1:1434', 'hmuuser', 'password');
Add a database name
$connection = mysqli_connect('127.0.0.1', 'hmuuser', 'password','dbname');
Also here is suggest - Actively refused it" means that the host sent a reset instead of an ack when you tried to connect. It is therefore not a problem in your code. Either there is a firewall blocking the connection or the process that is hosting the service is not listening on that port. This may be because it is not running at all or because it is listening on a different port.
I guess the problem is, that you use MySQLi to connect to a MSSQL server.
You should use the correct MSSQL extension instead.
Microsoft published their SQL-Server for PHP driver on GitHub: https://github.com/Microsoft/msphpsql
Or you use the older extension which is documented in the PHP manual: http://de2.php.net/manual/en/book.mssql.php
And at least you can set up ODBC.
One of them should resolve your problem.
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.
This might be ridiculously easy for you but I've been struggling with this for an hour... :(
<?php
$connect = mysql_connect("localhost:8080", "root", "mypassword");
echo($connect);?>
This is the code that I'm trying to run - you can see that I'm using 8080 as my port number and, of course, I have HTML codes as well.
However, it gives me the following error messages whenever I try to open the PHP file:
Warning: mysql_connect() [function.mysql-connect]: MySQL server has gone away in C:\wamp\www\php_sandbox\index.php on line 2
Warning: mysql_connect() [function.mysql-connect]: Error while reading greeting packet. PID=4932 in C:\wamp\www\php_sandbox\index.php on line 2
Warning: mysql_connect() [function.mysql-connect]: MySQL server has gone away in C:\wamp\www\php_sandbox\index.php on line 2
I don't know... what's wrong with this? Is it because of the port number?
Change localhost:8080 to localhost:3306.
Try opening Port 3306, and using that in the connection string not 8080.
Just Change the Connection mysql string to 127.0.0.1 and it will work
