我使用http.post调用PHP文件，在进程中传递json对象。 我已经设法从PHP中检索对象并在下面附加了转储。我现在需要的是检索姓名＆＃39;，＆＃39;电子邮件＆＃39;和＆＃39;消息＆＃39;数组中的字符串，但发现这很困难，因为不习惯PHP。

首先检索对象的PHP代码如下：
$data = json_decode(file_get_contents('php://input'), TRUE);
$text = print_r($data,true);
echo "<pre>";
var_dump($text);
echo "<br /><br />";
print_r($text);
echo "</pre>";
如何访问＆＃39;姓名＆＃39;，＆＃39;电子邮件＆＃39;和＆＃39;消息＆＃39;字符串好吗？

首先你的数组不是有效的...它应该是这样的：
BTW从数组内部删除$。
$newarr = Array(
"name" => Array(
"first_name" => "Alex",
"last_name" => "Gonzalez"
),
"email" => Array(),
"other_sub_array" => Array()
);
现在让我们说第一个名字，因为它是一个子阵列（所以在另一个数组中是一个数组）。
echo $newarr['name']['first_name'];
// Result: Alex
希望这有帮助。

我并不意味着无效，使用像这样的数组是不好的做法。

与其他答案不同，您的数组有效。我假设您正在使用一些框架来生成您正在阅读的相对奇怪的json。但到了这一点，您可以通过以下方式获取它们：
//note I used single quotes so that the dollar sign isn't evaluated to a php variable
$data['name']['$modelValue'];
$data['message']['$modelValue'];
$data['email']['$modelValue'];
