How can PHP be used to automate database queries for permission checks?

To automate database queries for permission checks in PHP, you can create a function that takes in the user's ID and the required permission level as parameters. This function can then query the database to check if the user has the necessary permission level. If the user has the required permission, the function can return true; otherwise, it can return false. 

function checkPermission($userID, $requiredPermissionLevel) {
    // Connect to the database
    $conn = new mysqli("localhost", "username", "password", "database");

    // Query the database to check if the user has the required permission level
    $query = "SELECT * FROM permissions WHERE user_id = $userID AND permission_level >= $requiredPermissionLevel";
    $result = $conn->query($query);

    // Check if the query returned any rows
    if ($result->num_rows > 0) {
        return true; // User has the required permission level
    } else {
        return false; // User does not have the required permission level
    }

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

// Example usage
$userID = 123;
$requiredPermissionLevel = 2;
if (checkPermission($userID, $requiredPermissionLevel)) {
    echo "User has permission to access this resource.";
} else {
    echo "User does not have permission to access this resource.";
}
