What are some recommended sources for documentation on PHP, MySQL, and phpMyAdmin?

When working with PHP, MySQL, and phpMyAdmin, it is important to have access to reliable documentation to help with troubleshooting, understanding syntax, and learning new features. Some recommended sources for documentation on PHP include the official PHP website (www.php.net), which offers a comprehensive manual with examples and explanations. For MySQL, the official MySQL documentation (dev.mysql.com/doc) provides detailed information on database management and query syntax. Additionally, phpMyAdmin's official documentation (docs.phpmyadmin.net) offers guidance on using the tool for database administration tasks.

// Example PHP code snippet using mysqli to connect to a MySQL database

$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);
}
echo "Connected successfully";
