服务器是我的电脑（http://127.0.0.1/），我检查了Cookie是否已创建。
这是我的代码。此代码按表单获得“selected_item_no”，并创建或覆盖cookie。查看评论为GetWorldTimerManager().SetTimer(HarvestTimerHandle, this, &ACubeFarmBlock::Harvest, HarvestTime,false);
的行：
//Issue is here <?php
session_start();
$selected_item_no=$_POST["selected_item_no"];
$search_item=$_POST["search_item"];
$search_text=$_POST["search_text"];
$isadded = 0;
if((trim($selected_item_no)!="")) {
if (isset($_COOKIE["maxcount"])) {
$maxcount = $_COOKIE["maxcount"];
for($ii=1;$ii<=$maxcount;$ii++){
////////// ISSUE IS HERE
if(isset($_COOKIE["cart_item_no[$ii]"])){ // this line doesn't work
/////////
$temp_item_no = $_COOKIE["cart_item_no[$ii]"];
if(trim($temp_item_no)===trim($selected_item_no)){
$temp_item_count = $_COOKIE["cart_item_count[$ii]"] + 1;
setcookie("cart_item_count[$ii]", $temp_item_count, time()+3600, "/");
$temp_arr_i = $ii;
$isadded = 1;
break;
}
}
}
if($isadded == 0){
$maxcount = $ii;
setcookie("maxcount", $maxcount, time()+3600, "/");
setcookie("cart_item_no[$maxcount]", $selected_item_no, time()+3600, "/");
setcookie("cart_item_count[$maxcount]", 1, time()+3600, "/");
$temp_arr_i = $ii;
}
} else {
$maxcount = 1;
setcookie("maxcount", $maxcount, time()+3600, "/");
setcookie("cart_item_no[$maxcount]", $selected_item_no, time()+3600, "/");
setcookie("cart_item_count[$maxcount]", 1, time()+3600, "/");
$temp_arr_i = $maxcount;
}
}
$temp_count_tt = $_COOKIE["cart_item_count[$temp_arr_i]"];
?>
<html>
<head>
<?php
include("./style.php");
?>
</head>
<body>
<?php
if((trim($selected_item_no)!="")) {
echo("$selected_item_no is added at $temp_arr_i . count: $temp_count_tt. isadded: $isadded.<br>");
var_dump($_COOKIE);
}
?>
是这样的。换句话说，var_dump($_COOKIE)被定义为$_COOKIE["cart_item_no"]！
$_COOKIE它不断增长。
我不知道如何解决这个问题...

你正在做错误的数组下载
正确的语法是$_COOKIE["cart_item_no"][$ii]，而不是$_COOKIE["cart_item_no[$ii]"]。
