PHP in a Nutshell

Name

sleep()

Synopsis

    int sleep ( int seconds )

The sleep() function pauses execution for a set number of seconds, determined by the parameter you provide it. For example:

    sleep(4);
    echo "Done\n";

The maximum script execution time is 30 seconds by default (although you may have changed this by altering the max_execution_time setting inside php.ini), but you can use sleep() to make your scripts go on for longer than that because PHP does not have control during the sleep operation.
