![]() ![]() I usually wouldn’t be doing a redirect with a simple form submission and just going from page 1 - page 3 but on this occasion i have been told this process needs to be kept. I cannot get the session variables to be displayed on the last page though! ![]() We can enable PHP output buffering to stop sending output to the browser and store it in a buffer instead.I have a basic php script over 3 pages based on sending input through a form, saving the posted data as session variables and redirecting the user to a new page.For being on the safe side we can put the exit command after the redirect statement of the PHP file.This will be helpful in such circumstances where the redirect should be done in the background. PHP redirect mechanism is used to navigate the user from one page to another without clicking any hyperlinks. Since HTML content should be sent before the redirect, we can separate PHP logic from HTML content.

We can specify either an absolute URL or a relative URL for this location header. Here are a few scenarios: Need to redirect users from the current domain to another Need to redirect one page to another on the same domain Need to redirect one page to another on an external domain Redirect selected pages or directory to another. In the above syntax of PHP redirect, we need to replace it with a valid URL to which we want to move. Sometimes, we move pages from location to another, so want to redirect users to updated URL. PHP Redirect Syntax header("Location: target-url") For that only, we have concluded with the JavaScript redirect article that server-side redirect is preferable. Unlike JavaScript redirect where there are several ways to handle URL redirect works based on the browser, PHP avoids such confusion and has a header() function to create the same effect in all browsers. Using this header() function, we need to send the location header by specifying the URL to which the page should be redirected. PHP provides predefined function, named header(),for URL redirection.
