$http_response_header

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

    $http_response_header — HTTP Response-Header

    Beschreibung

    Das $http_response_header-Array ist vergleichbar mit der Funktion get_headers(). Bei der Verwendung eines HTTP-Wrappers enthält $http_response_header die HTTP Response-Header. $http_response_header wird im lokalen Geltungsbereich von Variablen erstellt.

    Beispiele

    Beispiel #1 $http_response_header-Beispiel

    <?php
    function get_contents() {
    file_get_contents("http://example.com");
    var_dump($http_response_header); // die Variable wird im lokalen Geltungsbereich belegt
    }
    get_contents();
    var_dump($http_response_header); // ein Aufruf von get_contents() belegt die Variable nicht außerhalb des Funktionsbereichs
    ?>

    Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    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"
}

    Note that the HTTP wrapper has a hard limit of 1024 characters for the header lines.Any HTTP header received that is longer than this will be ignored and won't appear in $http_response_header.The cURL extension doesn't have this limit.http_fopen_wrapper.c: #define HTTP_HEADER_BLOCK_SIZE 1024
