What are the best practices for efficiently querying a MySQL database every second in PHP for event calculations?

To efficiently query a MySQL database every second in PHP for event calculations, it is recommended to use persistent database connections, optimize your queries, and consider implementing caching mechanisms to reduce the load on the database server. 

// Establish a persistent connection to the MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database_name");

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

// Loop to query the database every second
while (true) {
    // Execute your query here
    $result = $mysqli->query("SELECT * FROM events WHERE date >= NOW()");

    // Process the query result and perform event calculations

    // Sleep for 1 second before querying the database again
    sleep(1);
}

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