(PHP 5)

headers_list -- Returns a list of response headers sent (or ready to send)


array headers_list ( void )

headers_list() will return a numerically indexed array of headers to be sent to the browser / client. To determine whether or not these headers have been sent yet, use headers_sent().

Example 1. Examples using headers_list()


/* setcookie() will add a response header on its own */
setcookie('foo', 'bar');

/* Define a custom response header
   This will be ignored by most clients */
header("X-Sample-Test: foo");

/* Specify plain text content in our response */
header('Content-type: text/plain');

/* What headers are going to be sent? */


this will output :

array(4) {
  string(23) "X-Powered-By: PHP/5.1.3"
  string(19) "Set-Cookie: foo=bar"
  string(18) "X-Sample-Test: foo"
  string(24) "Content-type: text/plain"
