php - 如何使用 PHP 解析 JSON 字符串

Question

我有一个 JSON 字符串，其中包含 1-n 条纬度/经度记录。它看起来像这样:

{\"lat\":37.790388261934424,\"lng\":-122.46047996826172},{\"lat\":37.789608231530124,\"lng\":-122.46344112701416}

什么是解析它以获得 lat/lng 值循环的好方法？转义双引号会影响解析吗？

谢谢，亚历克斯

Answer 1

$ll = '[{"lat":37.790388261934424,"lng":-122.46047996826172},{"lat":37.789608231530124,"lng":-122.46344112701416}]';
$ll = json_decode($ll);
print_r($ll);

打印...

Array
(
    [0] => stdClass Object
        (
            [lat] => 37.7903882619
            [lng] => -122.460479968
        )

    [1] => stdClass Object
        (
            [lat] => 37.7896082315
            [lng] => -122.463441127
        )
