复制代码 代码如下:
function set_cronology($name,$value,$duration=7){
$duration=time()+(3600*24*$duration);
$max_stored_values=5;
if(isset($_cookie[$name])){
foreach($_cookie[$name] as $prop_crono=>$val_crono){
if($val_crono==$value)
return;
}
if($prop_crono<$max_stored_values)
setcookie($name.'['.($prop_crono+1).']',$value,$duration);
else{
array_shift($_cookie[$name]);
setcookie("$name[$max_stored_values]",$value,$duration);
}
}else
setcookie($name.'[0]',$value,$duration);
return;
}
?>
