Cant connect to DB. Won't Stop Loading - php

Question

I cant figure out why i am not connecting to my db. It seems like it is finding the host but having authentication problems or something. I am using xampp and the db provided with it. My connect code is as follows
<?php
$servername = 'localhost:1234';
$username = 'protech';
$password = '';
$dbname = 'protech';
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}else{
echo "Connected successfully";
}
mysqli_close($conn);
exit;
?>
if you need any information I am by my computer and will respond quick.
I get these error messages after waiting a while.
Warning: mysqli::__construct(): MySQL server has gone away in C:\xampp\htdocs\protech_connect.php on line 9

Answer 1

The standard port for mySQL is 3306 - so if you are genuinely using 1234 then append that as a new parameter to the db connection constructor.
$dbhost = 'localhost';
$dbuser = 'protech';
$dbpwd = 'xxx';
$dbname = 'protech';
$dbport = 1234;
$conn = new mysqli( $dbhost, $dbuser, $dbpwd, $dbname, $dbport );
if( $conn->connect_error ) exit( 'Bad foo: '.$conn->connect_error );
else { /* do exciting things */ }
$conn->close();

Answer 2

The mysqli_connect() function doesn't accept a port in the host parameter. You need to add the port number in another parameter like so:
$conn = mysqli_connect($servername, $username, $password, $dbname, $serverport);
Function documentation: mysqli::__construct()

Answer 3

If you get following error or problem then follow above solution.
Error:
Warning: mysqli_connect(): MySQL server has gone away
Warning: mysqli_connect(): Error while reading greeting packet. PID=3528
Warning: mysqli_connect(): (HY000/2006): MySQL server has gone away
Solution 1:
use 127.0.0.1 instead of localhost. Don't use any port number after 127.0.0.1.
Solution 2:
Check your host file located at
C:\Windows\System32\drivers\etc
and remove any localhost or 127.0.0.1 entry in file and save. You can use any HostEditor program to edit this file.
