我在JS中有一个2D数组。
我在ajax它之前警告数组并且数组完好无损并且一切都很好。
当我ajax它，我得到一个错误，所以我现在ajax'd数组到一个页面，只运行一个var转储和数组尾声中断并失去结构和数据
继承人js
$.ajax({
type: "POST",
url: "ajax/updateElements.php",
data: {outerarray:outerarray},
success: function(data){
alert("data="+data);
},
error: function(data){
alert("error");
}
});
php
<?php
var_dump($_POST['outerarray']);
?>
和返回的数据
data=array(40) {
[0]=>
array(20) {
[0]=>
string(2) "47"
[1]=>
string(2) "46"

那就是它的尾声
任何线索？ 在这个
上，我一直在墙上撞了一个星期继承PDO代码

好的，显然这是outerarray调用中$.ajax()数据对象序列化的问题（可能是一个旧的jQuery版本？）。为了避免任何问题，您可以将数据编码为JSON字符串并在PHP脚本中对其进行解码，基本上如下所示：
JS：
$.ajax({
type: "POST",
url: "ajax/updateElements.php",
data: {outerarray: JSON.stringify(outerarray)},
success: function(data) {
alert("data="+data);
},
error: function(data){
alert("error");
}
});
PHP：
$outerarray = json_decode($_POST['outerarray']);
...
$arraycount = count($outerarray);
for ($m=0; $m<$arraycount; $m++) {
$box_id = $outerarray[$m][0];
$top = $outerarray[$m][1];
...

检查php.ini设置中的post_max_size，并根据POST的大小检查它
