Wile connecting to MySql I am getting error "MySql server has gone away" on line "$db = mysqli_connect("localhost:9080","root","XXXX");"

Here is my code.

PHP

<?php
	ini_set('mysql.connect_timeout', 300);
	ini_set('default_socket_timeout', 300);
	
   define('DB_SERVER', 'localhost:9080');
   define('DB_USERNAME', 'root');
   define('DB_PASSWORD', 'XXXX');
   define('DB_DATABASE', 'api');
   
   //$db = mysqli_connect(DB_SERVER,DB_USERNAME,DB_PASSWORD);
   $db = mysqli_connect("localhost:9080","root","XXXX");
   
   // Check connection
	if (!$db) 
	{
		die("Connection failed: " . mysqli_connect_error());
	}
	
	$select_db = mysqli_select_db($db, DB_DATABASE);
	if(!$select_db)
	{
		die("Database selection failed: " . mysqli_error($db));
	}
	
	echo "Connected successfully";
?>

What I have tried:

Have added

ini_set('mysql.connect_timeout', 300);
ini_set('default_socket_timeout', 300);

Also updated max_allowed_Packet to 16 M.
Then Restart all Services.

Please post the full text of the error messages in your question, that image is unreadable.

Can you connect to the db using PhpMyAdmin ?

Looks like this was an incorrect port number, and has been solved on your StackOverflow copy of this question:

leave it as answer to close the Q&A ;-)

Done, although I don't usually like to do that, since I didn't come up with the answer. :)

Looks like this was an incorrect port number, and was solved on StackOverflow by RiggsFolly[^] :

"and port is 3307"
Then use define('DB_SERVER', 'localhost:3307');
Although the normal port is 3306 UNLESS you are actually using MariaDB when the default port is 3307

Solution 2

//Run SQL query/queries

// 1. Check "max_allowed_packet"
show variables like 'max_allowed_packet'

// 2. update "max_allowed_packet"
set global max_allowed_packet=33554432
