How can database flags be used to control the execution of specific actions in PHP scripts?

Database flags can be used to control the execution of specific actions in PHP scripts by storing a flag value in the database and checking it before executing the action. This can be useful for implementing features like enabling/disabling certain functionality or controlling access to specific parts of the application.

// Assume a database table named 'flags' with a column 'action_flag'

// Check the flag value before executing the action
$flag = // retrieve the flag value from the database

if ($flag == 1) {
    // Execute the specific action
    // Your code here
} else {
    // Flag is not set, do something else or display an error message
    // Your code here
}
