# DB-Connect MySQL (en)

Connect to a MySQL database with `mysqli_connect()` — pass in the servername, username and password. On success it prints "Connected successfully"; on failure `mysqli_connect_error()` returns the error message. `close()` closes the connection. Copy

```
<?php
$servername = "localhost";
$username = "username";
$password = "password";

// Create connection
$conn = mysqli_connect($servername, $username, $password);

// Check connection
if (!$conn) {
  die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";

$conn->close();
?>
```

**output:**

```
Connected successfully
```
