Cookie_history ($id, $info [' title '], $info [' Price '], $info [' pic '], $thisurl);

2.function.php inside Add code

/** +----------------------------------------------------------* 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 Cookieif (!cookie (' history ')) {//cookie null, initial a cookie (' 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);} Cookie (' history ', $history);}} /**  +----------------------------------------------------------* Web browsing record Read +----------------------------------------------------------*/ function Cookie_history_read () {$arr = Cookie (' history '), foreach ((array) $arr as $k = + $v) {$list [$k] = Json_decode ($v, true);} return $list;}
