How to parse a JSON string using PHP

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}

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

Thanks, Alex

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

Prints...

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:

$array = json_decode(stripslashes("[$input_string]"), 1);

Note that you will lose some precision on your float values in PHP.

Use json_decode.

You will need to unescape quotes first; just use 

$unescaped_data = str_replace('\"','"',$data)
