Can you refresh page with timing in php?

viruz

Is there a way/command in PHP to refresh the page? Like every 3 seconds, I want the page to refresh... Can you do that in php or does it have to be in java or some other language?... I've tried searching on php.net manual.. and couldn't find anything... So yea.. If someone could gimme a link or perhaps just the command/code it would be great......... 😃

PHP cannot do that once its finished executing on the server and outputs what is required mainly HTML it gets sent to the web server than the to the clients browser. PHP has stopped doing anything as soon as the Web Server gets involved again.

You can do a few things do it in Javascript or a meta refresh.

Look up the meta refresh HTML tag in Google. Or you could do it in PHP to with a simple

sleep(3);
header("Location: ".$_SERVER['PHP_SELF']);

or, the very first line after the <?

<? 
header('refresh: 3;');
// REST OF PAGE



?>

that is 3 seconds, change the 3 to the # you want

If you don't to put the head function at the top or you want have a refresh command inside a If statement u could use a javascript...

<SCRIPT language="JavaScript">
<!--
function redir()
{
window.location="index.php";
}

setTimeout("redir()",5000);

//-->
</SCRIPT>

5000 being milliseconds so if you want 3 seconds put 3000 instead of 5000

😃 thnx for help. I had some "header" error when I used the php I wasn't sure how you solve it... So I stuck with the java one and it works fine 🙂

kender

for header info -- header(); -- you need to have it at the very top of your script

header needs to be the first bit of information sent

so like before

<?
header('refresh: 3;'); 

// REST OF PAGE 


?>

hey.. it worked 🙂
edit: i just noticed soemthing.. it seems to skip 1 second sometime.. say i refresh the page and the time it says it 07:08:17 pm... and then 1 refresh is shows 07:08:22 pm... 07:08:28 pm in another refresh and so on and it eventually ends up to be 07:08:50 pm and then it goes by the 0-5-0-5-0-5s.. if you can follow this you can see that it kinda skips 1 second randomly.. I don't might but anyone know the reason? 😛
