To redirect to another URL or web page in PHP, you can use the header function with the Location header.
Here is an example of how to use the header function to redirect to another URL:
<?php
header('Location: http://www.example.com/');
exit;
This will redirect the client to the specified URL. It's important to note that the header function must be called before any output is sent to the client. This means that you should place the header function at the top of your PHP script, before any HTML or other output.
You can also use the header function to redirect to another page on the same website. For example:
<?php
header('Location: /another-page.php');
exit;
This will redirect the client to the another-page.php page on the same website.
It's important to note that the header function is not the only way to redirect to another URL or web page in PHP. You can also use JavaScript or an HTML meta tag to achieve the same result. Consult the PHP documentation and online resources for more information.
