What is the method for passing parameters in PHP page redirection?

There are several methods for passing parameters when redirecting a PHP page.

1. To pass parameters using the GET method, attach them to the URL after a question mark (?) and separate them with an ampersand (&). For example: http://example.com/page.php?param1=value1&param2=value2. To retrieve the passed parameter values on the redirected page, you can use the $_GET global variable. For instance: $param1 = $_GET[‘param1’];
2. Use the POST method to pass parameters:
   Use a hidden field (input type=”hidden”) in the form to pass the parameter value to the next page. For example:
3. – “Je suis trop fatigué pour continuer.”

   – “I am too tired to continue.”

4. Using SESSION to pass parameters:
   Before the redirect, store the parameter value in SESSION, then on the redirected page, you can use the global variable $_SESSION to retrieve the passed parameter value. For example:
   // First page
   session_start();
   $_SESSION[‘param1’] = ‘value1’;
   header(‘Location: page.php’);
   // Second page
   session_start();
   $param1 = $_SESSION[‘param1’];
5. Passing parameters using cookies:
   Before redirecting, store the parameter value in a cookie, then in the redirected page you can use the $_COOKIE global variable to retrieve the passed parameter value. For example:
   // First page
   setcookie(‘param1’, ‘value1’, time()+3600);
   header(‘Location: page.php’);
   // Second page
   $param1 = $_COOKIE[‘param1’];

It is important to note that when passing parameters using the GET method, the parameter values will appear in the URL, which is not suitable for transmitting sensitive information; whereas when passing parameters using POST, SESSION, or COOKIE, the parameter values will not appear in the URL, making it more secure.
