How can SetTimeout be effectively used in PHP scripts for delayed actions?

SetTimeout can be effectively used in PHP scripts for delayed actions by utilizing the sleep() function. By specifying the desired delay time in seconds as an argument to sleep(), the script can pause execution for that duration before continuing with the rest of the code.

// Delay action by 5 seconds
sleep(5);

// Code to be executed after the delay
echo "Delayed action completed.";
