Refresh a page using PHP

How can I refresh a page using PHP periodically? If I can not do it by PHP, what is the best recommended scenario?

You can do it with PHP:

header("Refresh:0"); 

It refreshes your current page, and if you need to redirect it to another page, use following:

header("Refresh:0; url=page2.php"); 

In PHP you can use:

$page = $_SERVER['PHP_SELF']; $sec = "10"; header("Refresh: $sec; url=$page"); 

Or just use JavaScript's window.location.reload().

You sure can refresh a page periodically using PHP:

<?php header("refresh: 3;"); ?> 

This will refresh the page every three seconds.

That is simply possible with header() in PHP:

header('Refresh: 1; url=index.php'); 

I've found two ways to refresh PHP content:

1. Using the HTML meta tag:

echo("<meta http-equiv='refresh' content='1'>"); //Refresh by HTTP 'meta' 

2. Using PHP refresh rate:

$delay = 0; // Where 0 is an example of a time delay. You can use 5 for 5 seconds, for example! header("Refresh: $delay;"); 

Besides all the PHP ways to refresh a page, the page will also be refreshed with the following HTML meta tag:

<meta http-equiv="refresh" content="5"> 

See Meta refresh - "automatically refresh the current web page or frame after a given time interval"

You can set the time within the content value.

header('Location: .'); seems to refresh the page in Chrome, Firefox, Edge, and Internet Explorer 11.

Echo the meta tag like this:

URL is the one where the page should be redirected to after the refresh.

echo "<meta http-equiv=\"refresh\" content=\"0;URL=upload.php\">"; 

You can refresh using JavaScript. Rather than the complete page refresh, you can give the contents to be refreshed in a div. Then by using JavaScript you can refresh that particular div only, and it works faster than the complete page refresh.

PHP is server-side language, so you can not refresh the page with PHP, but JavaScript is the best option to refresh the page:

location.reload(); 

The visit Location reload() method.

You cannot do it in PHP. Once the page is loaded, PHP dies and is out of control.

You have a few options:

• Use JavaScript
• Use the refresh meta tag, <meta http-equiv="refresh" content="5">

I think that the refresh meta tag is the easiest and most convenient.

Adding this meta tag in PHP might help:

echo '<META HTTP-EQUIV="Refresh" Content="0; URL=' . $location . '">'; 

One trick is to add a random number to the end of the URL. That way you don't have to rename the file every time. E.g.:

echo "<img src='temp.jpg?r=3892384947438'>" 

The browser will not cache it as long as the random number is different, but the web server will ignore it.

Add the following function to your project:

function redirect($filename) { if (!headers_sent()) header('Location: '.$filename); else { echo '<script type="text/javascript">'; echo 'window.location.href = \''.$filename.'\';'; echo '</script>'; echo '<noscript>'; echo '<meta http-equiv="refresh" content="0;url=\''.$filename.'\'" />'; echo '</noscript>'; } exit(); } 

function call:

redirect($_SERVER['REQUEST_URI']);
