What are the potential pitfalls of using the old mysql_* functions in PHP 5.3.x?

The potential pitfalls of using the old mysql_* functions in PHP 5.3.x include security vulnerabilities, lack of support for newer MySQL features, and deprecated functionality. To solve this issue, it is recommended to switch to MySQLi or PDO for database operations, as these provide better security and support for modern database features. 

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

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

// Perform a query using prepared statements
$stmt = $mysqli->prepare("SELECT * FROM table WHERE id = ?");
$stmt->bind_param("i", $id);
$id = 1;
$stmt->execute();
$result = $stmt->get_result();

// Fetch data
while ($row = $result->fetch_assoc()) {
    echo $row['column_name'] . "<br>";
}

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