Can’t send properly formatted JSON from .json file

[code=php]$file_name = $res[‘fileName’];
$file = file_get_contents($file_name);

$obj = json_decode($file,true);

echo $_GET[‘callback’] . ‘(“‘ . json_encode($obj) . ‘”);’;[/code]

That’s my script.

this is the .json file

[code=html]{“topic”:{“prefix”:”www.mysocialbeacon.com/files/tutorial/”,”slides”:[{“prefix”:”general/”,”topic”:”General”,”img”:”1.png”,”title”:”Welcome”]}}[/code]

basically I’m trying to return it to a javascript file and it’s wrapping quotes around the wrong part. Here’s the beginning of the response

“{“topic”:{“prefix”:”www.mysocialbeacon.com/files

Also in #PHP _↴
