从PHP文件中传递的参数检索数组元素

Question

I am calling a PHP file using http.post, passing a json object in the process. I have managed to retrieve the object from within the PHP and have attached the dump below. All I now need is to retrieve 'name', 'email' and 'message' strings from the array but am finding this difficult as not used to PHP.

                        [$name] => message

                    )

            )
            </pre>

The PHP code which retrieves the object in the first place is as follows:

$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>";

How can I access the 'name', 'email' and 'message' strings please?

Answer 1

First of all your array isnt a valid one... it should be something like this:

BTW remove the $ from inside the arrays.

$newarr = Array(
  "name" => Array(
    "first_name" => "Alex",
    "last_name" => "Gonzalez"
     ),
  "email" => Array(),
  "other_sub_array" => Array()
);

Now to get let say the first name, since it is a subarray (so an array inside another array).

echo $newarr['name']['first_name'];
// Result: Alex

Hope this helps.

UPDATE

I didn't mean not valid, it is a bad practice to use an array like that.
