我对 AS3 和 php 很陌生。尝试将数组从 Php 传递到 AS3 VO 文件，然后将其解析为 Vector，然后将它们打包在盒子中。发生了一件非常奇怪的事情，通过的第一个变量始终为空，我调换了位置，第一个变量仍然为空。但其余的变量都很好。如果有人可以解决我的问题，将非常感谢！忽略任何可能的 SQLi 注入问题，我还没有时间改变这些。谢谢！

php

<?php
ini_set('display_errors', 1); error_reporting(E_ALL);

session_start();

include 'connect.php';


$_SESSION['username'];
$username=$_SESSION['username'];


$result=mysqli_query($con,"SELECT * FROM Test WHERE username = '$username'")or die( mysqli_error($con));
$solutions = array();
$check_num_rows=mysqli_num_rows($result);

while ($row = mysqli_fetch_assoc($result))
{

        $solutions[5]=$row['LoZip1'];
      $solutions[2]=$row['rangelow1'];
       $solutions[3]=$row['rangehigh1'];
       $solutions[4]=$row['nobed1'];
}

echo "rangelow1=".$solutions[2];
echo "&rangehigh1=". $solutions[3];
echo "&bed1=".$solutions[4];
echo "&LoZip1=".$solutions[5];
?>

我有这个简单的测试代码和你的测试数据：

var s:String = "rangelow1=b&rangehigh1=bb&bed1=a&LoZip1=bb"; 
var u:URLVariables = new URLVariables(s); 
trace(u.bed1, u.LoZip1, u.rangelow1, u.rangehigh1);

而且它们都没有显示为空。所以解析看起来还可以，但是下面的逻辑是错误的：

if (books.indexOf(book) == books.length - 1) {
    finish()
}

URLLoader异步加载数据，因此不能保证所有书籍都会按照您请求的顺序加载。根据网络连接，最后一本书的数据可能会在前一本书的数据之前加载。在这种情况下，您将在finish. 为了解决这个问题，而不是indexof使用计数器变量来计算加载了多少本书并调用finish一次counter == books.length。

var counter:int = 0;

private function response(book:BookVO):void {
    counter++;

    if (counter == books.length) {
        finish();
    }
}
