Is PEAR necessary for using MySQL classes in PHP, or are there alternative options?

PEAR is not necessary for using MySQL classes in PHP. There are alternative options available such as using the MySQLi or PDO extensions in PHP to interact with MySQL databases. These extensions provide more modern and secure ways to work with MySQL databases compared to the older MySQL extension that PEAR offers.

// Example using MySQLi extension
$servername = "localhost";
$username = "username";
$password = "password";
$database = "dbname";

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

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

// Perform SQL queries using $conn object

// Close connection
$conn->close();
