$http_response_header - HTTP response headers

	The $http_response_header array is similar to the get_headers(3) function. When using the HTTP wrapper, $http_response_header will be pop-
       ulated with the HTTP response headers. $http_response_header will be created in the local scope.

       Example #1

	      $http_response_header example

	      <?php
	      function get_contents() {
		file_get_contents("http://example.com");
		var_dump($http_response_header);
	      }
	      get_contents();
	      var_dump($http_response_header);
	      ?>

	      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"
	      }
	      NULL
