php get values from json encode

Posted by: admin April 23, 2020 Leave a comment

Questions:

I have an url passing parameters use json_encode each values like follow:

$json = array
(
    'countryId' => $_GET['CountryId'],
    'productId' => $_GET['ProductId'],
    'status'    => $_GET['ProductId'],
    'opId'      => $_GET['OpId']
);

echo json_encode($json);

It’s returned a result as:

{  
  "countryId":"84",
  "productId":"1",
  "status":"0",
  "opId":"134"
}

Can I use json_decode to parse each values for further data processing?

Thanks.

How to&Answers:

json_decode() will return an object or array if second value it’s true:

$json = '{"countryId":"84","productId":"1","status":"0","opId":"134"}';
$json = json_decode($json, true);
echo $json['countryId'];
echo $json['productId'];
echo $json['status'];
echo $json['opId'];

Answer:

json_decode will return the same array that was originally encoded.
For instanse, if you

$array = json_decode($json, true);
echo $array['countryId'];

OR

$obj= json_decode($json);

echo $obj->countryId;

These both will echo 84.
I think json_encode and json_decode function names are self-explanatory…
