How Can I Redirect a PHP Page After Function Execution?

PHP Page Redirection After Function Execution

PHP provides functionality for redirecting pages after executing a function. To achieve this, follow these steps:

1. Use the header function:

   header("Location: http://www.yourwebsite.com/user.php");

   This will send a header to the browser to redirect to the specified URL.

2. Call exit():

   After calling header, it's good practice to immediately call exit() to prevent subsequent code from executing and potentially causing errors.

   header("Location: http://www.yourwebsite.com/user.php");
   exit();

Example:

if (...) {
    // I am using echo here.
} else if ($_SESSION['qnum'] > 10) {
    session_destroy();
    echo "Some error occurred.";

    // Redirect to "user.php".
    header("Location: user.php");
    exit();
}

Important Note:

Remember to call header() before sending any other output, including HTML tags and blank lines. Sending output before calling header() can result in errors.
