从REST API输出中解析JSON并将其放入相应的变量中

Question

I'm using php and got output from JIRA API like below which connects to tool using https://github.com/chobie/jira-api-restclient/blob/master/README.md. It fetches records very fine but i just want few information from all records so written below code with print_r($issue['description']) but it throws error:

Uncaught Error: Cannot use object of type chobie\Jira\Issue as array

1. What changes do I need to make in place of $issue to get these 3 information - [id:protected], [description] and [name].

2. How do I count total bugs found for e.g. number of chobie\Jira\Issue Object found?

Code:

$walker = new Walker($api);
$walker->push(
    'project = "SEA" AND (status != "closed" AND status != "resolved") ORDER BY priority DESC'
);

foreach ( $walker as $issue ) {
    print "<pre>";
    print_r($issue);
    print "</pre>";
}

So $issue prints everything like below but i just want to get [id:protected], [description] and [name]. What changes i need to make in place of $issue to get these 3 information. Can someone please give me some hint?

JSON:

chobie\Jira\Issue Object
(
    [id:protected] => 21373505
    [self:protected] => https://test.corp.com/rest/api/2/issue/21373505

    [fields:protected] => Array

                [colorName] => yellow

            )

        )

                [key] => indeterminate
                [colorName] => yellow
                [name] => In Progress
            )

        )

Got a answer, you need to convert object to array first, get array fields and parse it accordingly.

$walker = new Walker($api);
$walker->push('project = "SEA" AND (status != "closed" AND status != "resolved") ORDER BY priority DESC');

foreach ( $walker as $issue ) {
    $issue = $bugs->getFields();
    print "<pre>";
    print_r($issue);
    print_r(trim($issue['Status']['name']);
    print "</pre>";
}
