header()We will demonstrate another way to redirect a page in PHP using the function by sending an HTTP header to the browser . This method uses the built-in header()function in PHP, which takes Locationas a parameter, and its value is the URL of the desired page.

We'll also look at a way to redirect a page to another page using a helper function that takes the URL and status code as parameters, and then calls header()the function inside that method.

We will show another way to redirect to another page using PHP's echointernal javascriptredirect, which uses PHP's window.locationto store the URL of the page to redirect.

Use the function in PHP header()to send the URL as an HTTP header to the browser

We can use header()the header function, which takes Locationas a parameter. LocationThe value of is the URL of the desired page, to which we need to redirect. Note that the header function should be written in the file above the HTML tags and text. The header function does not execute after the other data is sent to the browser header(). It should be the first line of code to be executed.

For example, http://facebook.comstore the URL in a variable redirect_page. Use header()the function and Locationspecify the variable in the function's redirect_page. Then, call die()the function.

In the example below, the URL of Facebook is stored redirect_pagein the variable. The variable is used in the title function. When you run the following script, the page will redirect to the Facebook homepage. The function will block the script from continuing header()after the function is executed die()to prevent unexpected behavior. Make sure to place the PHP file in your local web server so you can run it in your browser.

Sample code:

# php 7.x
<?php
$redirect_page = 'http://test.com';
header('Location:'  .$redirect_page);
die();
?>

Use Helper method in PHP header()to redirect to other pages through function with status code

We will use a helper function redirectto redirect pages to other pages.

Define a method redirect. Pass the URL and status code as parameters in the function. header()Write the function inside the method. Pass Locationthe URL and status code as header()parameters to the function. Then, call die()the function. The script header()dies after executing the function because it encounters die()the function. Outside the function definition, call the function providing the URL http://example.com/ as a parameter redirect. It calls the function with the URL as a parameter.

In the following example, status codes 301are used to permanently redirect to another page. This script redirects the current page to http://example.com/. Check out the MDN web documentation to learn 303more about status codes.

Sample code:

#php 7.x
<?php
function redirect($url, $statusCode = 301) {
    header('Location: '  . $url, $statusCode);
    die();
}
redirect('http://example.com/');
?>

Redirecting to another page using output buffering in JavaScript

We will use JavaScript in PHP to redirect a page to another page. In the following example, we will redirect the page to the Twitter homepage.

Type the tag script text/javascriptas to write some JavaScript code. Use window.locationto store the URL -
http://www.demo.com. Use to echoprint the entire scripttag.

This method is called buffered output. It is a faster way to redirect to another page. Please check the PHP official website to know more about buffered output.

Sample code:

#php 7.x
<?php
echo '<script type="text/javascript">
    window.location = "http://www.demo.com/"
    </script>';
?>
