11. Page Redirection

Write a PHP script to redirect a user to a different page.

Sample Solution:

PHP Code:

<?php
// Use the header function to send a raw HTTP header
// In this case, the header function is used to perform a redirection
// The 'Location' header specifies the URL to which the user will be redirected
header('Location: https://www.w3resource.com/');
?>

Explanation:

• PHP Opening Tag: <?php is used to open a PHP script.
• Header Function:
• The header() function is a PHP function that sends a raw HTTP header to the client.
• In this example, the function is used to set a redirection header.
• Location Header:
• The header('Location: https://www.w3resource.com/'); line tells the browser to redirect to the specified URL (https://www.w3resource.com/).
• The "Location" header indicates the new destination for the browser.
• Redirection Behavior:
• When this code is executed, the user's browser automatically navigates to the specified URL.
• No additional HTML or PHP output is sent to the browser after this redirection command if it's followed immediately by a script termination (recommended best practice).
• Important Note:
• It's a best practice to use exit(); or die(); right after the header() function to stop further code execution, ensuring the redirection happens immediately.

Output:

View the output in the browser

header() function:

Syntax:

void header ( string $header [, bool $replace = TRUE [, int $http_response_code ]] )

header() is used to send a raw HTTP header.

Parameters:

• header: The header string.
• replace: The optional replace parameter indicates whether the header should replace a previous similar header, or add a second header of the same type.
• http_response_code: Forces the HTTP response code to the specified value. Note that this parameter only has an effect if the header is not empty.

For more Practice: Solve these Related Problems:

• Write a PHP script to conditionally redirect users based on their geographical location.
• Write a PHP script to implement a delayed redirection with a visible countdown timer.
• Write a PHP script to perform a redirection using header() and include a fallback meta refresh.
• Write a PHP script to redirect users and simultaneously log the redirection event in a file.
