Are there any best practices for ensuring that a database operation is only executed once a day in PHP?

To ensure that a database operation is only executed once a day in PHP, you can use a combination of PHP and SQL to check if the operation has already been performed on the current day before executing it. One way to achieve this is by storing a timestamp in the database when the operation is performed and then comparing it with the current date before executing the operation again. 

<?php
// Connect to your database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check if the operation has already been performed today
$query = "SELECT * FROM daily_operations WHERE operation_date = CURDATE()";
$result = $conn->query($query);

if ($result->num_rows == 0) {
    // Perform the database operation
    // Your code here

    // Insert a record to indicate that the operation has been performed today
    $insertQuery = "INSERT INTO daily_operations (operation_date) VALUES (CURDATE())";
    $conn->query($insertQuery);
} else {
    echo "Operation already performed today.";
}

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