I have Json in PHP like this:

$json = '{"total":"100", "page":"1", "records":"100", "rows": [ 
{"no":"1","part_number":"2","part_name":"3","price":"4","note":"8"}]}';

and I want to add

"test1":"5","test2":"7"

into JSON above.

so it will be like this:

$json = '{"total":"100", "page":"1", "records":"100", "rows": [ 
    {"no":"1","part_number":"2","part_name":"3","price":"4","test1":"5","test2":"7","note":"8"}]}';

Please, help me. How to add attribute in JSON in PHP?

  • You could parse the json string into an array using `json_decode`, add the new attributes to the array, and recreate the json string using `json_encode`. – FThompson Jun 19 '13 at 16:19

  • the examples in http://stackoverflow.com/questions/1745052/add-new-data-into-php-json-string use array definitions. Rio is wanting to add attributes(properties) – user20232359723568423357842364 Jun 19 '13 at 16:30
  • @user20232359723568423357842364: You can simply pass `true` as second argument to `json_decode`. No difference. Apparently 4 years ago people didn't require so much hand-holding. – Felix Kling Jun 19 '13 at 16:35
  • Beginners have always required hand-holding ;) 4 years ago there weren't as many around here – user20232359723568423357842364 Jun 19 '13 at 16:44

$json = '{"total":"100", "page":"1", "records":"100", "rows": [ 
{"no":"1","part_number":"2","part_name":"3","price":"4","note":"8"}]}';

// decode json
$json = json_decode($json);

// add data
$json->rows[0]->test1 = "5";
$json->rows[0]->test2 = "7";

// echo it for testing puproses
print_r($json);
// re-encode 
$json = json_encode($json);

echo $json;
