Object of class stdClass could not be converted to string PHP issue

Im pulling info from Jira Atlassian API, ive worked with other code and it works fine and i change it to json and all the info gets returned as an object.

However in this case i get this server error: PHP Catchable fatal error: Object of class stdClass could not be converted to string in /usr/local/vhosts/999/webspace/httpdocs/mysite/filters1.php on line 411

Now here is the code im trying to run:

$username = '[email protected]';
$password = 'xxxxxxx';

$url = 'xxx.atlassian.net/rest/api/2/search?jql=project+%3D+bug+AND+component+%3D+%22issues%22+AND+status+in+(Open,+Reopened)';


$headers = array(
'Accept: application/json',
'Content-Type: application/json'
);


$ch = curl_init();
$test = "This is the content of the custom field.";

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
//curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");


$result = curl_exec($ch);
$issue_json = json_decode($result);
$ch_error = curl_error($ch);

if ($ch_error) {
    echo "cURL Error: $ch_error";
} else {
    echo $issue_json;
}

curl_close($ch);

As i mentioned that returns the error above but if i alter the code to

 $result = curl_exec($ch);
 //$issue_json = json_decode($result);

and then i echo out $result it works and returns everything i need but as a huge string and not an object like i want. I formatted the whole string below so its a bit more readable. I googled some similar issues and i think i need to do something like this:

foreach($string as $strings) 
{
     echo $strings;
}

But i not too familiar with this kind of stuff just basic php so im a bit lost

The function json_decode does not return a string.

Have a look at the documentation for the function.

http://fr2.php.net/function.json-decode.php

The problem is that you're trying to echo the object. The following code is faulty.

echo $issue_json;

You can use var_dump to see the structure of the object returned from json_decode.

var_dump($issue_json);
