How to access the attributes within this JSON string in PHP - php

Question

So I have this array that saves a json string.
Array
(
[0] => "2jDQoU9D2wu04wqkg0ImUI":{"date":"2016-08-02 14:08:49","type":"story","story_id":"2jDQoU9D2wu04wqkg0ImUI","series_id":"1RAv0uDbcIieYgYqywqYmk"}
)
I want to be able to access just the value "2jDQoU9D2wu04wqkg0ImUI" at the start of the json string and then also be able to do something like $value[0]['type'] to get the type from this json string object. I'm pretty new to PHP and struggling to get this working. I've tried JSON encoding/decoding and can't seem to get anything to work.
What's the proper way to go about this? Thanks in advance.

Answer 1

I hope this code will solve your problem.
$array[0] = '"2jDQoU9D2wu04wqkg0ImUI":{"date":"2016-08-02 14:08:49","type":"story","story_id":"2jDQoU9D2wu04wqkg0ImUI","series_id":"1RAv0uDbcIieYgYqywqYmk"}';
//print_r($arr);
$JsonString = '{' . $array[0] . '}';
$json = json_decode($JsonString);
foreach($json as $key => $value){
echo "Key : $key <br />";
echo "Type : ". $value->type."<br />";
echo "date : ". $value->date."<br />";
echo "story_id : ". $value->story_id."<br />";
echo "series_id : ". $value->series_id."<br />";
}

Answer 2

so you have array $jsonArray and you want to access just the key of it
if its single dimension array :
echo key($jsonArray); //prints 2jDQoU9D2wu04wqkg0ImUI
Otherwise if its multidimensional you can loop through it and do whatever you want with each key
foreach($jsonArray as $key => $value) {
echo $key; //prints 2jDQoU9D2wu04wqkg0ImUI
}

Answer 3

Try this:
$arrayOfObjects = [];
foreach($array as $key => $value) arrayOfObjects[] = json_decode($value);
Now you can loop through this new $arrayOfObjects
foreach($arrayOfObjects as $key => $object){
echo $object->date . '<br>';
echo $object->type . '<br>';
echo $object->story_id . '<br>';
echo $object->series_id . '<br> ==== >br> ';
}
