How to create JSON response in PHP file? - php

Question

I'd like to get JSON response on my second server with the domain example.com where the getit.php file contains:
$arr = array('antwort' => 'jo');
echo json_encode($arr);
Now when I try to get it with my first server:
$url = 'http://www.example.com/getit.php';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$antwort = curl_exec($ch);
curl_close($ch);
$antwort = json_decode($antwort);
echo '<pre>';
var_dump($antwort);
echo '</pre>';
I get:
object(stdClass)#2 (1) {
["antwort"]=>
string(4) "jo"
}
And not an normal array, how do I convert this to array?
I allready tried $antwort = json_decode(json_encode($antwort), True); but I only get a weird string with that?!

Answer 1

JSON's definition is: JavaScript Object Notation. JavaScript arrays can only have numeric keys. Your array has string keys, therefore it MUST be encoded as a JavaScript OJBECT, which do allow string keys.
Tell json_decode() you want arrays instead:
$arr = json_decode($json, true);
^^^^
as per the docs
Where how did you do your json_decode(json_encode($antwort))? The ONLY way that'd return a string is if you encoded the $antwort you'd gotten from curl_exec().
