How to integrate paypal sandbox in php [duplicate] - php

Question

I have the following code in a codeigniter REST app (built using: https://github.com/chriskacerguis/codeigniter-restserver)
public function fullname_get()
{
$fullname = array("fname"=>"john", "lname"=>"doe");
$data["json"] = json_encode($fullname);
$this->response($data["json"], 200);
}
When I call the API, this return json that looks like this:
{\"fname\":\"john\",\"lname\":\"doe\"}
The above json string fails http://jsonlint.com/ test because of the escape character "\".
Just wondering how I can work around this?
I'm building a REST api that is supposed to return json ... and I have to make sure it's legit json.
Thanks.

Answer 1

Try this
$fullname = array("fname"=>"john", "lname"=>"doe");
$this->response($fullname, 200);//it sends data json format. You don't need to json encode it
You got that response because your data is json encoded twice

Answer 2

You have to strip slashes, use this stripslashes(json_encode($fullname)). Full code mention below:
public function fullname_get()
{
$fullname = array("fname"=>"john", "lname"=>"doe");
$data["json"] = stripslashes(json_encode($fullname));
$this->response($data["json"], 200);
}
I hope this will solve your issue.

Answer 3

It is legit JSON - and you didn't write a test ;)
{
"fname": "john",
"lname": "doe"
}
Please see the demo over at http://ideone.com/5IW1Ef
The class you are using does magical things:
$this->response($this->db->get('books')->result(), 200);
and based on the format specified on the URL the response data is converted to JSON. You don't have to do the JSON encoding.
Please read the examples provides here

$fullname = array("fname"=>"john", "lname"=>"doe");
$this->response($fullname, 200);
