如何在PHP中添加JSON中的属性？

Question

我在PHP中使用Json是这样的:

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

我想补充一下

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

进入JSON上面.

所以它会是这样的:

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

Answer 1

$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;
