Clear previously set headers php

Question

I would like to know if its possible to clear the current information stored in header_list()

if(headers_sent()){
    foreach(headers_list() as $header){
                


        

Answer 1

To remove them all it's pretty simple:

if ( ! headers_sent() ) {
    header_remove();
}

No looping required. If you don't pass a parameter to header_remove, it removes all headers set by PHP.
