[SOLVED] Sleep()

[Northern Flame]

I was reading about the sleep() function and if I understood it

correctly, it just makes the script load a certain amount of

seconds slower. My question is, when would this apply to real

life coding? In other words, when would I use the sleep() function

and what exactly would I use it for?

 

thanks for any replies

(i know this sounds like a noob question  )

Its probably not of that much use in a web programming environment such as how php is normally used, though I have used in on a few occasions within shell scripts. It does what is says, sleeps for (n) seconds.

 

A simple (be it useless) example would be to ping a server every 5 seconds.

 

#!/usr/bin/php
<?php

  while (true) {
    shell_exec('ping foo.com');
    sleep(5);
  }

?>

somewhere I read too that using this when working with

sensitive data such as passwords can lower the chances

of the values being changed or something like that in a

hack attempt, is this true? how would that work?

Sorry, but that doesn't make allot of sense.

I think he's got this backwards 0.o ... wouldn't slowing it down make it more vulnerable?

No, the fact of the matter is the request has been sent, doesn't matter how fast / slow the server takes to respond, the request remains the same.
