PHP MySQL PDOException: "could not find driver"

[JohnFischer]

I am receiving the following Error Message:

"There was an error connecting to the database.

Error message: could not find driver"

My GoDaddy package includes Linux with cPanel. I have mysqli, mysqlnd, pdo, pdo_mysql, pdo_sqlite and other modules enabled with PHP current version 7.1.

Here is my database.php code:

<?php
$dsn = "MySQL:host=11.62.0.35;dbname=newdatabase";
$username = "memyselfi";
$password = "pa55w0rd";
$options = array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION); try {
    $db = new PDO($dsn, $username, $password, $options);
} catch (PDOException $e) {
    $error_message = $e->getMessage();
    include 'DatabaseError.php';    exit;
}
?>

Here is my DatabaseError.php code:

...
    <main>        
	<h1>Database Error</h1>
        <p>There was an error connecting to the database.</p>
        <p>Error message: <?php echo $error_message; ?></p>
    </main>
...

There appears to be a step I am missing.

GoDaddy recommended I change the script to use MySQLi, thus I changed the code as follows:

<?php
$host = "11.62.0.35";
$dbname = "newdatabase";
$username = "jmemyselfi";
$password = "pa55w0rd";

$dbConn = new mysqli($host, $username, $password, $dbname);
if ($dbConn->connect_errno) {
    echo "Sorry, this website is experiencing problems.";
    echo "Error: Failed to make a MySQL connection, here is why: \n";
    echo "Errno: " . $dbConn->connect_errno . "\n";
    echo "Error: " . $dbConn->connect_error . "\n";
    exit;
}
?>

I received the following error message:

Warning: mysqli::__construct(): (HY000/2003): Can't connect to MySQL server on '11.62.0.35' (110) in /home/ds3tjvumtdmc/public_html/ourlittlechurch/model/database.php on line 7

I knew the IP address of the web-site and MySQL database were two different addresses. I thus made the assumption I could not use host=localhost, but that was the solution. Once I used "localhost", the error message went away in mysqli coding. I reversed the code back for PDO and "localhost" also resolved that code.

Solution:

$host="localhost";

and

$dsn = "MySQL:host=localhost;dbname=newdatabase";
