why this warning came ::::::mysql_connect(): php_network_getaddresses: getaddrinfo failed: No such host is known [closed]
(1 answer)
Closed 8 years ago.
so this is my code:
<?php
class DB{
private $host = 'loscalhost';
private $user = 'root';
private $password = '';
function __construct(){
try {
$connect_db = mysql_connect($this->host, $this->user, $this->password);
}catch(Exception $e){
echo 'DB connection failed: ', var_dump($e), "\n";
}
}
}
I changed the host variable value so i can display the message DB connection failed..., but my question is why is it not displayed? instead i get this: Warning: mysql_connect(): php_network_getaddresses: getaddrinfo failed: No such host is known
Host name is localhost but you used loscalhost
private $host = 'loscalhost';
should be
private $host = '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

Trying to connect to local Mysqli DB.
Database Connection:
<?php $con= new mysqli("localhost","Kobe24","Kobei987","Bkn_Data");
if ($con->connect_error) {
die("Connection failed: " . $con->connect_error);
}
Returns this:

Any feedback would help. Been researching this problem but no definitive solutions.
Can you try this mysqli_connect() functions as per code below.
Please also ensure that database user and password are correct and that the user has permission to connect to the database
<?php
$dbhost = 'localhost:3306';
$dbuser = 'enter database user';
$dbpass = 'enter password';
$con = mysqli_connect($dbhost, $dbuser, $dbpass);
if(! $con ){
die('Could not connect: ' . mysqli_error());
}
echo 'Connected successfully';
mysqli_close($con);
?>

Message: mysqli::real_connect(): php_network_getaddresses: getaddrinfo failed: No such host is known
(2 answers)

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 am using the following php code to connect to a remote database:
<?php
error_reporting(E_ALL);
ini_set( 'display_errors','1');
$db_host = "host";
$db_user = "user";
$db_pass = "pass";
$db_name = "name";
try{
$dbc = new PDO("mysql:dbname=$db_name;host=$db_host",$db_user,$db_pass);
}
catch(PDOException $e){
echo '<p>There was a problem with your connection: '.$e->getMessage().'</p>';
}
$query = "some query";
$results = $dbc->query($query);
$row = $results->rowCount();
?>
But it keeps generating the following error message:
Warning: PDO::__construct(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /example.php on line 11
There was a problem with your connection: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known
//shouldn't this error below not even show because the try never completes?

In my PHP apicación I connect to a MySQL database with PDO, but I'm having the following problem, the error message;
Warning: PDO :: __construct () [pdo. - Construct]: [2002]
"No connection Could be made Actively Because the target machine refused it."
(trying to connect via tcp :/ / localhost: 3306)
Fatal error: Uncaught exception 'Exception' with message 'Connection failed: SQLSTATE [HY000] [2002]
The code to access the database is:
private $db = NULL;
const DB_SERVER = "localhost";
const DB_USER = "root";
const DB_PASSWORD = "usbw";
const DB_NAME = "status_poster";
public function __construct() {
//**below the error here!!**
$dsn = 'mysql:dbname=' . self::DB_NAME . ';host=' . self::DB_SERVER;//
//var_dump($dsn);
try {
$this->db = new PDO($dsn, self::DB_USER, self::DB_PASSWORD);
} catch (PDOException $e) {
throw new Exception('Connection failed: ' . $e->getMessage());
}
return $this->db;
}
What I find strange is that the same parameters to connect to "mysqli" I have no problems and I connect successfully, run CRUD statements and no problems, the code is as follows;
The code
function getProducts() {
$products = array();
$mysqli = new mysqli("localhost", "root", "usbw", "Datos");
if (mysqli_connect_errno()) {
printf("Error in conection: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Id,sku,name,price FROM products";
if ($result = $mysqli->query($query)) {
while ($obj = mysqli_fetch_object($result)) {
//instructions...
}
}
$mysqli->close();
return $products;
}
Well, I need to connect with PDO but I can not find the solution,
waiting for suggestions or help!
Sorry, can not find in the forum how to respond with a picture, but is this;
solve my problem, change the port from 3307-3306 (3306 was the port that went out in error) of USBWebserver. now work!
note: above the port was 3307
