1.試験方法www.xxx.com/test.php?content_id=自己定義、例えば:44

 
  
$content_id = array();//1.       
  
$content_id[] = $_GET['contentid']; //2.     ID        
  
 
  
if(isset($_COOKIE['content_id'])) //3.  cookie    ,      (      ) 
  
{ 
  
$now_content = str_replace("\\", "", $_COOKIE['content_id']);//(4).      cookie,    unserialize      ,           
  
$now = unserialize($now_content); //(5). cookie   serialize              
  
foreach($now as $n=>$w) { //(6).      ,    foreach    
  
if(!in_array($w,$content_id)) //(7).         ,                 ; 
  
{ 
  
$content_id[] = $w; //(8).      
  
} 
  
} 
  
$content= serialize($content_id); //(9).           
  
setcookie("content_id",$content, time()+3600*24); //(10).   cookie 
  
 
  
}else { 
  
$content= serialize($content_id);//4.
