Convert response to readable form

Question

I am posting request to paypal using curl.

Please check following code

$url = 'https://api-3t.sandbox.paypal.com/nvp';
$request = array();

$request['USER'] = 'username' ;
   ---  sending other request fields like above --- 

$rd = '';

foreach ($request as $_key => $_val) 
 {
   $rd .= $_key . '=' . urlencode(mb_convert_encoding($_val, 'ISO-8859-1', 'UTF-8')) . '&';
}

$output = array();

$curlSession = curl_init();

curl_setopt($curlSession, CURLOPT_URL, $url);
curl_setopt($curlSession, CURLOPT_HEADER, 0);
curl_setopt($curlSession, CURLOPT_POST, 1);
curl_setopt($curlSession, CURLOPT_POSTFIELDS, $rd);
curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curlSession, CURLOPT_TIMEOUT, 90);
curl_setopt($curlSession, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curlSession, CURLOPT_SSL_VERIFYHOST, 1);

$rawresponse = curl_exec($curlSession);

Now when curl execution is performed I am getting below reposne.

TIMESTAMP=2015%2d07%2d23T10%3a39%3a36Z&CORRELATIONID=61f4332aaf13e&ACK=Success&VERSION=90&BUILD=17485293

My issue is how to convert this in readable array form ? Please help me

Answer 1

Let's say the variable $response contains what you get from paypal.

$decoded = urldecode($response);

will get you

TIMESTAMP=2015-07-23T10:39:36Z&CORRELATIONID=61f4332aaf13e&ACK=Success&VERSION=90&BUILD=17485293

further calling

$split = explode('&', $decoded);

will get you

Array
(
    [0] => TIMESTAMP=2015-07-23T10:39:36Z
    [1] => CORRELATIONID=61f4332aaf13e
    [2] => ACK=Success
    [3] => VERSION=90
    [4] => BUILD=17485293
)

You can even split further each element by = and get a key value pair.

[Edit]

Or better yet

$arr = array();
parse_str(urldecode($response), $arr);
echo "<pre>"; print_r($arr);

will get you

Array
(
    [TIMESTAMP] => 2015-07-23T10:39:36Z
    [CORRELATIONID] => 61f4332aaf13e
    [ACK] => Success
    [VERSION] => 90
    [BUILD] => 17485293
)
