我如何获得一个 json value 值？

Question

这是我的 php 代码

echo $_POST[result];

这是我的 php 结果

{
"result_code":0,
"err_cd":"",
"result_msg":"",
"store_id":"M20C2685",
"status":"APPROVED",
"order_no":"600a2a044c9be",
"tr_no":725,
"tr_price":1000,
"pay_price":1000,
"approved_day":"20210122",
"approved_time":"102744",
"param1":"",
"param2":""
}

我想一个一个打印出每个值。我该怎么办？

Answer 1

json_decode 正在解析 JSON

<?php

$str = '{"result_code":0,
"err_cd":"",
"result_msg":"",
"store_id":"M20C2685",
"status":"APPROVED",
"order_no":"600a2a044c9be",
"tr_no":725,
"tr_price":1000,
"pay_price":1000,
"approved_day":"20210122",
"approved_time":"102744",
"param1":"",
"param2":""
}';

$arr = json_decode($str, true);
echo $arr['err_cd'] . PHP_EOL;
echo $arr['result_msg'] . PHP_EOL;
echo $arr['store_id'] . PHP_EOL;
echo $arr['status'] . PHP_EOL;
// ......


// Circulates each value in the array
foreach ($arr as $item) {
    echo $item . PHP_EOL;
}
