PHP - wait a couple of seconds before continuing?

I've set up a HTML form and I'm using PHP to verify that everything is good before displaying a message on the webpage. I then want to redirect the user back to the home page after a couple of seconds.

Problem is, I can't find a way to wait 5 seconds or so and then do the redirect. The sleep function simply waits 5 seconds and then displays the message/redirects at the same time. Anyone got any ideas?

Thanks!

<?php
    if (empty($_POST) === false) {
    echo 'Success! You will not be able to log in until an administrator approves your account.';
    sleep(5);
    $url = 'index.html';
    echo '<META HTTP-EQUIV=Refresh CONTENT="0; URL='.$url.'">';  
}
?>

Here is something I worked up to redirect. Seems to work fine and thought I would share.

DelayTime(15); 

echo "<script>window.top.location.reload();</script>";

The DelayTime Function: 

function DelayTime($secs){
      $now = time();
      while($now < ($now + $sec)){ 
        $now = time();
        if($now >= ($now + $sec)){ break; }
      }
      return true;
}

For a practical (works across the board AFAIK) but not standardized solution, use the Refresh HTTP header:

header('Refresh: 5; url=http://yoursite.com/index.html');

Otherwise, you can achieve the effect with a <meta> tag but without involving sleep():

// This goes inside <head>, so obviously *before* the "success" message!
echo '<META HTTP-EQUIV=Refresh CONTENT="5; URL='.$url.'">';

That is because the output is not sent to the browser sequentially. PHP sends out the output mostly in one go, after the script has terminated.

Instead use this meta-tag for waiting in html:

<meta http-equiv="Refresh" content="5; URL=/blah;">

Note that <meta> tags always should be put inside <head>.

Note that the browser can always choose to ignore redirects. And, although that is my personal opinion, redirects like this suck. Rather display a notice flash message at the top of the next pageload imho.

The way you do such redirections is javascript

Make a small javascript function like

function delayer() {
    window.location = "http://example.com"
}

and add it with

onLoad="setTimeout('delayer()', TIME_IN_MILLISECONDS_TO_WAIT)"

inside your html body tag

This should be done on the client side using javascript for example.

<?php
    if (empty($_POST) === false) {
    echo 'Success! You will not be able to log in until an administrator approves your account.';
    sleep(5);
    $url = 'index.html';
    header("location: ".$url);  
}
?>

if it don't work need to use javascript

<script type="text/javascript">
setTimeout("window.location = 'index.html'", 2000);
</script>
