What impact does the correct connection to the server and database have on successful data insertion in PHP?

Having the correct connection to the server and database is crucial for successful data insertion in PHP. Without a proper connection, the PHP script will not be able to communicate with the database server, resulting in failed data insertion attempts. To solve this issue, ensure that the connection details in the PHP script match the server and database credentials. 

// Database connection details
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
