PHP breaks code after redirect?

I have a very simple question ... In the php function, I redirect if the value returns FALSE, otherwise continuing the code.

flibbertigibbet() { $value = true_or_false(); if ($value == FALSE) { //redirect to another controller method } //the rest of the code }

What happens after the redirect? Can the code break or run a little if you say .. redirection takes longer to load?

Is it good to use exit() after a redirect?

The code will continue to run - not only when the redirect takes longer, but each time from nd to the end.

If you use exit() , it depends on whether you want the rest of the code to execute. You can set header() and send a new address, but you can still perform some actions after that - for example, updating the database or some other bits.

I usually think that it is best to do all the necessary updates and send header() right at the end of the page - it makes debugging a lot easier and more intuitive.

Just setting the redirect header does nothing on its own. ALWAYS exit or die after setting the location header (unless you know exactly what you are doing)

It really depends on what you mean by redirection. Yes, it will never run the rest of the code if it is something like:
header("Location: http://newurl.com");

Otherwise, if there is no good reason for not returning (infinite loops, you try to include content that takes too long and does not set a timeout, you use exit() ...), then the rest of the code will be launched, as soon as the if condition code completes.
