Getting a php array - php

Question

I need to interpret the array received from a remote licensing.
I am calling the remote api via curl and the answer in the browser is:
The parsed answer from curl done by using:
parse_str(curl_exec($ch), $parsed);
print_r($parsed);
is exactly as here:
Array ( [{"success":true,"uses":154,"purchase":{"id":"GYFt6sW7hbURSVdSpipb5g] => =","created_at":"2015-06-06T16:44:41Z","email":"askolon11#gmail.com","full_name":"daniel","variants":"","custom_fields":[],"product_name":"Direkt 1.2","subscription_cancelled_at":null,"subscription_failed_at":null}} )
I tried already for several hours to get the "success" item so later on to check it if it is true or false.
I used
while (list($var, $val) = each($parsed)) {
print "$var is $val\n";
}
but the result is the same.
Also I tried:
$parsed[0]['success'] or $parsed[0]['success']
and no result as well.
My full code is:
<?php $ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.gumroad.com/v2/licenses/verify");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, true);
$data = array( 'product_permalink' => 'skQsA', 'license_key' => 'AB26AD9D-1B3B42E0-92356540-CF4E7C1B' );
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$output = curl_exec($ch);
$info = curl_getinfo($ch);
$output = array();
parse_str(curl_exec($ch), $parsed);
print_r($parsed); // HERE WE HAVE THE ARRAY
while (list($var, $val) = each($parsed)) {
// print "$var is $val\n";
}
curl_close($ch);
?>
Thank you.

Answer 1

The API seems to return a JSON encoded string. So instead of:
parse_str(curl_exec($ch), $parsed);
use:
$parsed = json_decode(curl_exec($ch), true);
Then a print_r($parsed) will output:
Array
(
[success] => 1
[uses] => 154
...
)
And for checking success value:
if ($parsed['success']) {
// Do stuff
}

Answer 2

Instead of doing
$parsed[0]['success'];
try just
$parsed['success'];
If the array you are getting back is an associative array, then the 'key' will be the word 'success'.
$parsed = [
"success" => true,
"uses" => 154,
"purchase" =>
[
"id" => "GYFt6sW7hbURSVdSpipb5g] => =",
"created_at" => "2015-06-06T16:44:41Z",
"email" => "askolon11#gmail.com",
"full_name" => "daniel",
"variants" => "",
"custom_fields" => [],
"product_name" => "Direkt 1.2",
"subscription_cancelled_at" => null,
"subscription_failed_at" => null
]];
if($parsed['success'])
echo 'true';
else
echo 'false';
