Bagaimana untuk menetapkan pengepala p3p dalam php?

PHP mencapai akses merentas domain ke COOKIE dengan menetapkan pengepala P3P

Sistem saya ialah CentOS (kernel Linux)

Edit HOST

vi /etc/hosts

Sertai

127.0.0.1        www.a.com
127.0.0.1        www.b.com

Pertama: Cipta fail a_setcookie.php dengan kandungan berikut:

<?php 
//header(&#39;P3P: CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR"&#39;); 
setcookie("test", $_GET[&#39;id&#39;], time()+3600, "/", ".a.com"); 
?>

Kemudian: Cipta fail a_getcookie.php dengan yang berikut kandungan:

<?php 
var_dump($_COOKIE); 
?>

Akhir sekali: Cipta fail b_setcookie.php dengan kandungan berikut:

<script src="http://www.a.com/a_setcookie.php?id=www.b.com"></script>

----------------- ---- －－－－－－－

Selepas tiga fail dibuat, kami mengaksesnya mengikut urutan melalui penyemak imbas:

http://www.b.com/b_setcookie.php
http://www.a.com/a_getcookie.php

Kami akan mendapati bahawa apabila mengakses b domain .com, kami Tiada nilai kuki ditetapkan dalam domain a.com.

Kemudian kami mengubah suai fail a_setcookie.php dan mengalih keluar simbol ulasan a_setcookie.php ialah:

<?php  
header(&#39;P3P: CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR"&#39;);  
setcookie("test", $_GET[&#39;id&#39;], time()+3600, "/", ".a.com");  
?>

Lawatinya semula melalui penyemak imbas:

http://www.b.com/b_setcookie.php
http://www.a.com/a_getcookie.php

Kali ini, anda akan mendapati bahawa apabila mengakses domain b.com, kami menetapkan nilai kuki domain a.com.

Akhirnya, nampaknya hanya IE yang mempunyai sekatan yang lebih ketat terhadap akses merentas domain ke COOKIE Kod di atas telah diuji di bawah FIREFOX dan ia boleh berjaya walaupun tanpa menghantar maklumat pengepala P3P.
