[Function] $http_response_header

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.

PHP5 에서 get_headers()와 비슷한 기능합니다. 주어진 URL에서 header 를 배열로 반환 합니다.
PHP4 에서 get_headers()를 대신 해서 쓸 수 있습니다.

예)

<?php
file_get_contents("http://google.co.kr"); 
var_dump($http_response_header);
?>

출력 :
array(19) { [0]=> string(30) "HTTP/1.0 301 Moved Permanently" [1]=> string(34) "Location: http://www.google.co.kr/" [2]=> string(38) "Content-Type: text/html; charset=UTF-8" [3]=> string(35) "Date: Wed, 25 Feb 2009 02:33:36 GMT" [4]=> string(38) "Expires: Fri, 27 Mar 2009 02:33:36 GMT" [5]=> string(38) "Cache-Control: public, max-age=2592000" [6]=> string(11) "Server: gws" [7]=> string(19) "Content-Length: 221" [8]=> string(17) "Connection: Close" [9]=> string(15) "HTTP/1.0 200 OK" [10]=> string(35) "Date: Wed, 25 Feb 2009 02:33:39 GMT" [11]=> string(16) "Pragma: no-cache" [12]=> string(38) "Expires: Fri, 01 Jan 1990 00:00:00 GMT" [13]=> string(50) "Cache-Control: no-cache, no-store, must-revalidate" [14]=> string(39) "Content-Type: text/html; charset=EUC-KR" [15]=> string(89) "Set-Cookie: IGTP=; expires=Thu, 01-Jan-1970 00:00:01 GMT; path=/; domain=www.google.co.kr" [16]=> string(157) "Set-Cookie: PREF=ID=f91f35dde9284d31:NW=1:TM=1235529219:LM=1235529219:S=SPZzoz0uILEOZgpW; expires=Fri, 25-Feb-2011 02:33:39 GMT; path=/; domain=.google.co.kr" [17]=> string(12) "Server: igfe" [18]=> string(17) "Connection: Close" }
