这个问题在这里已有答案：

• Converting PHP result array to JSON 2回答

将字符串更改为数组是

$string = '[{"name":"jack","address":"who knows"},{"name":"jill","address":"who knows too"}]';

$array = json_decode($array,true);

但是，如果它反过来将数组更改为字符串

$array = [{"name":"jack","address":"who knows"},{"name":"jill","address":"who knows too"}];

$string = $array; // $string is $string like on first example

Answer 1

您可以使用json_encode作为：

$string = '[{"name":"jack","address":"who knows"},{"name":"jill","address":"who knows too"}]';
$array = json_decode($string,true); // convert string -> array
$string = json_encode($array); // convert array -> string 
echo $string; // will output the original string
