Array element retrieval from passed parameter in a PHP file - php

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.

</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.

Answer 2

Your array is valid unlike the other answer supposes. I assume that you are using some framework that generates the relatively strange json you're reading in. But to the point you can get them via:
//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'];
