php get values from json encode

Question

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.

...What? You're not seriously trying to json_encode something in PHP, then json_decode it later in the same PHP? I'm so confused. — FrankieTheKneeMan

He might want to store encoded json somewhere for future use — Vladimir Hraban

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'];

How can i get value from this [{"countryId":"84","productId":"1","status":"0","opId":"134"}]

Mihai Iorga Over a year ago

@151291 $json[0].countryId

@MihaiIorga the right solution is $json[0]->countryId, not $json[0].countryId because dot is user for string concatenation in php.

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...
