Is the use of the mysql extension in PHP considered outdated?

The use of the mysql extension in PHP is considered outdated and deprecated. It is recommended to use the newer mysqli or PDO extensions for interacting with MySQL databases in PHP. This is due to security vulnerabilities and lack of support for newer MySQL features in the mysql extension.

// Connect to MySQL using the mysqli extension
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Perform a query
$result = $mysqli->query("SELECT * FROM table");

// Fetch data
while ($row = $result->fetch_assoc()) {
    // Do something with the data
}

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