[英]How to parse a JSON string using PHP
I have a JSON string that has 1-n numbers of lat/lng records. 我有一个JSON字符串,其中包含1-n个lat / lng记录。 It looks something like this:
它看起来像这样:
{\"lat\":37.790388261934424,\"lng\":-122.46047996826172},{\"lat\":37.789608231530124,\"lng\":-122.46344112701416}
What is a good way to parse this to get lat/lng values loop? 解析这个以获得lat / lng值循环的好方法是什么? And do the escaped double quotes impact the parsing?
转义的双引号会影响解析吗?
Thanks, Alex 谢谢,亚历克斯
Use json_decode. 使用json_decode。
You will need to unescape quotes first; 你需要先引用引号; just use
只是用
$unescaped_data = str_replace('\"','"',$data)
$ll = '[{"lat":37.790388261934424,"lng":-122.46047996826172},{"lat":37.789608231530124,"lng":-122.46344112701416}]';
$ll = json_decode($ll);
print_r($ll);
Prints... 打印...
Array
(
[0] => stdClass Object
(
[lat] => 37.7903882619
[lng] => -122.460479968
)
[1] => stdClass Object
(
[lat] => 37.7896082315
[lng] => -122.463441127
)
)
In your case it's probably best to use: 在您的情况下,最好使用:
$array = json_decode(stripslashes("[$input_string]"), 1);
Note that you will lose some precision on your float values in PHP. 请注意,在PHP中浮点值会丢失一些精度。
JSON_decode并删除转义引号
