What are some potential methods for executing commands on a server with time delays in PHP?

When executing commands on a server with time delays in PHP, one potential method is to use the sleep() function to introduce a delay before executing the command. This can be useful for scenarios where you need to wait for a certain amount of time before running a command, such as in a cron job or a scheduled task.

// Introduce a 5-second delay before executing the command
sleep(5);

// Execute the command
$command = "your_command_here";
$output = shell_exec($command);
echo $output;
