我有一个相当复杂的对象，它是用PHP构造的，并使用JSON发送给JQuery。 这个过程非常有效，但到目前为止我在解决这个问题上没有运气。出于某种原因，我没有看到这里发生了什么 - 仍然在2天后，所以有人可以指出我正确的方向。
我有许多构建对象的函数。它们都运行良好，在流程结束时，JSON在JQuery中成功解析。从数据库中获取数据并执行一些简单算法的其中一个函数始终导致JSON解析错误。此函数将stdClass子对象数组添加为主对象的属性。通过在构造过程中不调用此函数，JSON解析错误就消失了。
这是我到目前为止所发现的（为了简单起见，我已将问题区域隔离开来）
//The $dataObject is derived from a database with:
$dataObject = $db->loadObjectList(); // Using Joomla framework
001: // The section of code in php which illustrates the problem
002: $jsonOutput = json_encode($dataObject);
003: dump($jsonOutput, '$jsonOutput');
004: echo $jsonOutput;
005: // Here are the results:
006: // Dumping the array of stdClass objects to JDump produces the following:
007: $jsonOutput = {"resourceList":
008: [
009: {
010: "assetCategory":"Accommodation",
011: "assetCount":"1"
012: },
013: {
014: "assetCategory":"Equipment",
015: "assetCount":"3"
016: }
017: ]
018: }
019: // This is what is produced on screen with echo command.
020: {"resourceList":[,]}
// The individual sub-objects are not produced in the output.
我不知道为什么会这样。我尝试过不同的密钥名称，子对象定义名称等无济于事。
在整个模型构造函数中，我在同一位置调用了其他函数而不是这个函数，并且没有问题。我不知何故仅限于此功能。
将原始JSON转储到JDump实用程序中，产生预期的结果，但使用echo在浏览器的屏幕上产生结果，产生一个格式错误的“无”数组，导致JQuery中的JSON解析错误线。
有没有人对此有任何想法？
提前致谢

使用json_encode生成的完整对象然后是echo：

您可以在最后清楚地看到格式错误的对象。
echo '<pre>'.print_r($dataObject, true).'</pre>';的输出产生以下内容：
