如何使用PHP解析JSON字符串 [英] How to parse a JSON string using PHP

问题描述

我有一个JSON字符串，其中包含1-n个纬度/经度记录.看起来像这样:

I have a JSON string that has 1-n numbers of lat/lng records. It looks something like this:

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

什么是解析此值以获得lat/lng值循环的好方法?转义的双引号会影响解析吗?

What is a good way to parse this to get lat/lng values loop? And do the escaped double quotes impact the parsing?

谢谢， 亚历克斯

推荐答案

$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
        )
