Google翻译API无法对JSON进行PHP解码

Question

I'm trying to decode this JSON returned by Google Translation Service:

$r = '[[["Hola Mundo","Hello World",,,1]],,"en"]'

But when I do this:

echo json_decode($r);

it returns me null.

I got this manual maded for JS, just trying to made it with PHP

To clarify your issue,

JSON is a string (and in PHP should be quote encapsulated), in your code, you have not declared it as a string but an array, and just to be clear you can instantiate an array with a couple methods:

$myArray = array();
$myArray2 = [];

So to fix your issue; encapsulate your JSON string, replace echo json_decode($r) with var_dump($r) and voila

Eg

$r = '[[["Hola Mundo","Hello World",,,1]],,"en"]';
var_dump(json_decode($r));

BUT that is not valid JSON syntax (check on http://jsonlint.com/ )
