PHP-如何遍历此json响应？

Question

I have a json response from an API and I can't create an array from it with "json_decode" in PHP to iterate through this as an array. I always get "NULL", when I use "var_dump" to print out, what my "json_decode" returns. The response-header of this API response is "application/json", but I am not familiar with this json format.

The json response from the API looks like this:

[1,"Example name","307","7","Test","455",1458572100000]
[1,"Another example name","146","7","Test","455",1458571500000]
[1,"Test","304","7","Test","455",1458572280000]
[1,"Example name 3","163","7","Hello world","455",1458571080000]

This is the result/response of a single API request. Now, for example, I want to get the penultimate number (in this case everytime 455) of every line/object or, for example, the name (second value: "Example name", "Another example name", "Test" and so on). How can I do this with php and this json format? It would be nice, if I can get an array from this to iterate through.

It's a local realtime bus arrival API, but it's similar to/the same as content.tfl.gov.uk/… and I call this API with a simple http/get request using file_get_contents in PHP

"/interfaces/ura/instant_V1?returnList=stopID,stopPointName,LineID,DestinationT‌​ext,estimatedTime,vehicleID&vehicleID=455")

To clarify, that's not JSON format that you're getting back. But if that's what you're getting then you need a solution :)

I would ignore the first & last character and use str_getcsv() to return the comma separated string as an array:

$input = '[1,"Example name","307","7","Test","455",1458572100000]';
$array = str_getcsv(substr($input, 1, -1));

If you are having multple lines, then you'll want to split them into individual lines before doing the above with:

$lines = explode($input, "]");
$array = array();
foreach($lines AS $line) {
    $input = '[1,"Example name","307","7","Test","455",1458572100000]';
    $array[] = str_getcsv(substr($input, 1, -1));
}
