# $http_response_header

(PHP 4 >= 4.0.4, PHP 5, PHP 7, PHP 8)

$http_response_header — HTTP response headers

### Description

The $http_response_header array is similar to the get_headers() function. When using the HTTP wrapper, $http_response_header will be populated with the HTTP response headers. $http_response_header will be created in the local scope.

### Examples

Example #1 $http_response_header example

    <?phpfunction get_contents() {  file_get_contents("http://example.com");  var_dump($http_response_header); // variable is populated in the local scope}get_contents();var_dump($http_response_header); // a call to get_contents() does not populate the variable outside the function scope?>

The above example will output something similar to:

    array(9) {
      [0]=>
      string(15) "HTTP/1.1 200 OK"
      [1]=>
      string(35) "Date: Sat, 12 Apr 2008 17:30:38 GMT"
      [2]=>
      string(29) "Server: Apache/2.2.3 (CentOS)"
      [3]=>
      string(44) "Last-Modified: Tue, 15 Nov 2005 13:24:10 GMT"
      [4]=>
      string(27) "ETag: "280100-1b6-80bfd280""
      [5]=>
      string(20) "Accept-Ranges: bytes"
      [6]=>
      string(19) "Content-Length: 438"
      [7]=>
      string(17) "Connection: close"
      [8]=>
      string(38) "Content-Type: text/html; charset=UTF-8"
    }
