What are the key considerations when implementing SSL encryption in PHP scripts for database connections?

When implementing SSL encryption in PHP scripts for database connections, the key considerations include ensuring that the server supports SSL connections, obtaining the necessary SSL certificates and keys, and configuring the PHP script to use SSL for database connections. This helps to secure the data transmitted between the PHP script and the database server, protecting it from potential eavesdropping or tampering. 

<?php
$servername = "your_server";
$username = "your_username";
$password = "your_password";
$database = "your_database";

$mysqli = new mysqli($servername, $username, $password, $database);

if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Enable SSL encryption
$mysqli->ssl_set('path_to_client_key.pem', 'path_to_client_cert.pem', 'path_to_ca_cert.pem', null, null);

if (!$mysqli->real_connect($servername, $username, $password, $database)) {
    die("Connection failed: " . $mysqli->connect_error);
}

echo "Connected successfully";

// Use the $mysqli object for database operations

$mysqli->close();
?>
