访问数组内的数组

Question

I am working on a Jira project and I am returning a data from API query. The data is json_encode format.

I am having problem with access an array inside an array.

Here's the json_encode data that I am working.

            "aggregatetimespent":null
         }
      }
   ]
}

Here's my snippet PHP code to access the record and print.

foreach ($json_output->issues as $issues) {

    echo "{$issues->key}";
    echo "{$issues->fields->summary}";
    echo "{$issues->fields->created}";
    echo "{$issues->fields->reporter->name}";

}

Now when I want to access the customfield_11054 so I could print the list of servers

server1, server2, server3, server4, server5, server6, server7, server8, server9, server10,
server11, server12, server13

so I add this

foreach ($json_output->issues as $issues) {

    echo "{$issues->key}";
    echo "{$issues->fields->summary}";
    echo "{$issues->fields->created}";
    echo "{$issues->fields->reporter->name}";
    echo "{$issues->fields->customfield_11054}";    
}

But I am getting result as an array.

Answer 1

print_r($issues->fields->customfield_11054);

It IS an array, which is why it says it's an array. If you wanted to get the values you'd have to wrap another foreach there:

foreach ($json_output->issues as $issues) {

    echo $issues->key;
    echo $issues->fields->summary;
    echo $issues->fields->created;
    echo $issues->fields->reporter->name;
    foreach($issues->fields->customfield_11054 as $customField)
    {
        echo $customField;
    }
}

Also, as a side note you don't need to put your variables in "{}" to print them out. They're strings, so just using echo $variable; will work just fine (as I've put in the above snippit).
