How can beginners improve their understanding of PHP syntax for database connections?

Beginners can improve their understanding of PHP syntax for database connections by studying the basics of PHP and SQL, practicing writing and executing PHP scripts that interact with databases, and referring to online tutorials and documentation. Additionally, using PHP frameworks like Laravel or CodeIgniter can provide built-in database connection features and make it easier to work with databases in PHP.

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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