Redirect URL in PHP

Header function

This is very simple way to redirect a web page to another web page using PHP at server side. To redirect your site visitors to a new page or new website, you just need to add a header function is first line of the web page. It works almost all browser.

 

redirect-in-php

Syntax

<?php

Header("Location: Web page address");

?>

Example of redirect

<?php
/* Redirect browser from current web page to another */

Header("Location: another-page.php");
?>

It is extremely important that you understand that the header() function must be called before any actual output is displayed to the browser.

Header function must be first of you web page because no actual output is sent, as shown below

Example

<?php
echo "Hello world";
echo "ptutorial.com";
header("Location: new-page.php");
exit;
?>

Note: Make sure all the actual code after the header function not get executed so don’t write anything after header function.

Absolute / relative path

If the destination web page is on the other server include complete URL like that http://www.ptutorial.com.

Example

<?php
header("Location: http://www.ptutorial.com");
exit;
?>

You can also use relative path for redirection like below shown.

Example

<?php
header("Location: ../new.php");
exit;
?>

Redirect after particular time

Redirect a webpage to another web page after defined time, use below syntax.

Example

<?php
  header( "refresh:5;url=http://www.ptutorial.com" );
  exit;
?>

Redirect with proper message

Redirect a webpage to another web page after defined time and proper message like “you are redirected after 5 second or any other”, use below syntax

Example

<?php
   header( "refresh:4; url=http://www.ptutorial.com" );
   echo "You will be redirected after 4 second";
?>
