/**
+----------------------------------------------------------
* Browse records sorted by Time
+----------------------------------------------------------
*/
function My_sort ($a, $b) {
$a = substr ($a, 1);
$b = substr ($b, 1);
if ($a = = $b) return 0;
return ($a > $b)? -1:1;
}
/**
+----------------------------------------------------------
* Web browsing record generation
+----------------------------------------------------------
*/
function Cookie_history ($id, $title, $price, $img, $url) {
$dealinfo [' title '] = $title;
$dealinfo [' price '] = $price;
$dealinfo [' img '] = $img;
$dealinfo [' url '] = $url;
$time = ' t '. Now_time;
$cookie _history = Array ($time => json_encode ($dealinfo)); Set cookies
if (!cookie (' history ')) {//cookie null, initial one
Cookies (' History ', $cookie _history);
}else{
$new _history = array_merge (Cookie (' history '), $cookie _history);//Add New browsing data
Uksort ($new _history, "My_sort"); Sort by browse time
$history = Array_unique ($new _history);
if (count ($history) > 4) {
$history = Array_slice ($history, 0,4);
}
Cookies (' history ', $history);
}
}
/**
+----------------------------------------------------------
* Web browsing record reading
+----------------------------------------------------------
*/
function Cookie_history_read () {
$arr = Cookie (' history ');
