Message: mysqli::real_connect(): php_network_getaddresses: getaddrinfo failed: No such host is known
(2 answers)
Closed 1 year ago.
I tried to connect to phpMyAdmin database but encounter an error Warning: mysqli::mysqli(): php_network_getaddresses: getaddrinfo failed: No such host is known. Below coding is the one that I currently use.
$servername = "http://localhost:8080";
$username = "root";
$password = "";
$db = "dbLogin";
$conn = new mysqli($servername, $username, $password, $db);
if ($conn->connect_error) {
die("Connection failed: ".$conn->connect_error);
}
else {
echo "Connection success!";
}
When I run my system, It will still show the message connection success! but together with the error I mentioned.
replace server name from
$servername = "http://localhost:8080";
to
$servername = "localhost";

I'm bulding an Intranet for my workplace and I need to connect it to a Database. I already have a script that connect my website throught XAMPP on PHPmyadmin, but now my boss asked me to connect the website to a database we have on Microsoft SQL server Management program and maybe I'm stupid but I'm not understanding how to do it and what's the difference.
And also: to connect to Microsoft SQL i use windows authentication so I dont know what to write on the php script.
This is my connect.php script I have and works on PHPMYADMIN:
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "intranet";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
?>
And this is the one I wrote for the database I have on Microsoft SQL (I change the server cause it's the one I use to connect when I open the program):
<?php
$servername = "EDP004\SQLEXPRESS";
$username = "root";
$password = "";
$dbname = "INTRANET_DD";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
?>
And this is the error I get on browser:
Warning: mysqli::__construct(): php_network_getaddresses: getaddrinfo for EDP004\SQLEXPRESS failed: unknown Host. in C:\xampp\htdocs\log\material\center\html\scripts\config.php on line 8
Fatal error: Uncaught mysqli_sql_exception: php_network_getaddresses: getaddrinfo for EDP004\SQLEXPRESS failed: unknown Host. in C:\xampp\htdocs\log\material\center\html\scripts\config.php:8 Stack trace: #0 C:\xampp\htdocs\log\material\center\html\scripts\config.php(8): mysqli->__construct('EDP004\\SQLEXPRE...', '', '', 'INTRANET_DD') #1 C:\xampp\htdocs\log\material\center\html\index.php(2): require_once('C:\\xampp\\htdocs...') #2 {main} thrown in C:\xampp\htdocs\log\material\center\html\scripts\config.php on line 8
Imagine I can access a MariaDB Database via phpmyadmin, e.g.
https://test.com/phpMyAdmin
username: some_username
password: some_password
Now I just want to use php to search whether some value exists; However, to do so I need to connect to the database with a servername, username and password;
I tried the servername
https://test.com`
with username and password as above but no luck; Is there a way to find that out?
Right now my currect code looks like that:
<?php
$servername = "https://test.com";
$username = "some_username";
$password = "some_password";
$conn = new mysqli($servername, $username, $password, "DB1");
// Überprüfe Verbindung
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
?>
which gives me the error
Warning: mysqli::__construct(): php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\xampp\htdocs\test.php on line 9
Warning: mysqli::__construct(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\xampp\htdocs\test.php on line 9

PHP Connection failed: SQLSTATE[HY000] [2002] Connection refused

Closed 3 years ago.
I am new in php and doing a login/register page in localhost using xampp on mac. I am having a trouble with this error:
Warning: mysqli_connect(): (HY000/2002): Connection refused in /opt/lampp/htdocs/website/includes/dbh.inc.php on line 9
Connection failed: Connection refused
I have tried changing the code but it continuously adding more problems.
This is my code:
<?php
$servername = "192.168.64.2:8080";
$dBUsername = "root";
$dBPassword = "";
$dBName = "loginsystem";
$conn = mysqli_connect($servername, $dBUsername, $dBPassword, $dBName);
if (!$conn) {
die("Connection failed: ".mysqli_connect_error());
}
How can I eliminate this error?
If you want to connect to other port than the default one, add the port argument when you establish the connection, not define it within the server name.
$servername = "192.168.64.2";
$dBUsername = "root";
$dBPassword = "";
$dBName = "loginsystem";
$dbPort = "8080";
$conn = mysqli_connect($servername, $dBUsername, $dBPassword, $dBName, $dbPort);
if (!$conn) {
die("Connection failed: ".mysqli_connect_error());
}
Another thing is to make sure you have the right port of MySQL service, port 8080 is commonly picked as the alternative for port 80 to handle HTTP request. Check your XAMPP configuration to find out which port is used for MySQL.
I am facing database connection error in Cpanel hosting with below code;
<?php
$servername = "localhost";
$username = "helloDB";
$password = "MY_PASS";
$conn = mysqli_connect($servername, $username, $password);
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
?>
Error Log...

I get the following error when I try to establish a connection to my database using mysqli:
Warning: mysqli_connect(): php_network_getaddresses: getaddrinfo

Below is my php code for connecting to the database:
$host_name = "127.0.0.1";
$database = "db565263480";
$user_name = "dbo565263480";
$password = "emarps2015!";
$link = mysqli_connect('localhost', $user_name, $password, $database);
// check connection
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
Please advise what am I doing wrong?
