How to Redirect a PHP Page After Function Execution Using header()?
Nov 30, 2024 am 09:34 AMRedirecting PHP Page After Function Execution
In PHP, it is possible to execute a function and then redirect the user to a different page within the same root folder. This can be achieved using the header() function.
Code Example:
Consider the following PHP code snippet:
if (...) { // I am using echo here. } else if ($_SESSION['qnum'] > 10) { session_destroy(); echo "Some error occured."; // Redirect to "user.php". header("Location: user.php"); exit(); }
Explanation:
- header("Location: user.php");: This line sends a special HTTP header to the browser, instructing it to redirect the user to the specified URL ("user.php").
- exit();: It is recommended to call exit() after the header() function to prevent any subsequent code from executing and potentially interfering with the redirect process.
Considerations:
- header() must be called before any output is sent to the browser, including HTML tags or blank lines. Failing to do so will result in an error.
- Verify that the redirect code runs before any other output is generated.
- Avoid using echo or other output commands before header(), as it can interfere with the redirect process.

To completely destroy a session in PHP, you must first call session_start() to start the session, and then call session_destroy() to delete all session data. 1. First use session_start() to ensure that the session has started; 2. Then call session_destroy() to clear the session data; 3. Optional but recommended: manually unset$_SESSION array to clear global variables; 4. At the same time, delete session cookies to prevent the user from retaining the session state; 5. Finally, pay attention to redirecting the user after destruction, and avoid reusing the session variables immediately, otherwise the session needs to be restarted. Doing this will ensure that the user completely exits the system without leaving any residual information.
