An example of an AI chatbot conversation about using the header function in PHP.
How do I use the header function in PHP?
The header function in PHP is used to send raw HTTP headers to the client. You can use it to redirect users or set content types.
Can you give me an example of how to redirect a user using the header function?
Sure! You can use it like this: header('Location: http://www.example.com'); This will redirect the user to the specified URL.
Are there any headers I should avoid sending?
Yes, you should avoid sending headers after any output has been sent to the browser. Always call header before any HTML output.
What happens if I try to send a header after output?
If you try to send a header after output, you'll get a 'headers already sent' warning, and the header won't be sent.
