PHP Echo不仅显示我需要的完整JSON行数据

Question

recently i used some JSON data in JQuery. now i want the same thing in PHP. For Example:

MySQL query returns data like

$result='{"username":"john","age":"18", "birthdate":"19880221"}';

but when i echo this data in PHP, like:

echo $result.username;
echo $result.age;

it shows output:

{"username":"john","age":"18", "birthdate":"19880221"}.username
{"username":"john","age":"18", "birthdate":"19880221"}.age

but i want output this:

John
18

PHP is not Javascript, the . operator is for string concatenation and PHP has no native support for JSON syntax. You need to convert the JSON formatted data into an array and use array syntax:

$result = json_decode($result, true);
echo $result['username'];
echo $result['age'];
