How to select value from array

Question

I'm getting PHP array from Here Maps:

array(1) {
["Response"] => array(2) {
    ["MetaInfo"] => array(1) {
        ["Timestamp"] => string(28)
        "2020-04-26T17:28:14.089+0000"
    } ["View"] => array(1) {
        [0] => array(3) {
            ["_type"] => string(21)
            "SearchResultsViewType" ["ViewId"] => int(0)["Result"] => array(1) {
                [0] => array(5) {
                    ["Relevance"] => float(1)["MatchLevel"] => string(11)
                    "houseNumber" ["MatchQuality"] => array(4) {
                        ["Country"] => float(1)["City"] => float(1)["Street"] => array(1) {
                            [0] => float(0.9)
                        } ["HouseNumber"] => float(1)
                    } ["MatchType"] => string(12)
                    "pointAddress" ["Location"] => array(6) {
                        ["LocationId"] => string(28)
                        "NT_uIrE4zNUPdurm.zAQNkxHA_0A" ["LocationType"] => string(7)
                        "address" ["DisplayPosition"] => array(2) {
                            ["Latitude"] => float(52.14242)["Longitude"] => float(20.71666)
                        } ["NavigationPosition"] => array(1) {
                            [0] => array(2) {
                                ["Latitude"] => float(52.14251)["Longitude"] => float(20.71668)
                            }
                        } ["MapView"] => array(2) {
                            ["TopLeft"] => array(2) {
                                ["Latitude"] => float(52.1435442)["Longitude"] => float(20.7148282)
                            } ["BottomRight"] => array(2) {
                                ["Latitude"] => float(52.1412958)["Longitude"] => float(20.7184918)
                            }
                        } ["Address"] => array(10) {
                            ["Label"] => string(38)
                            "ulica Rynek 4, 05-840 Brwinów, Polska" ["Country"] => string(3)
                            "POL" ["State"] => string(16)
                            "Woj. Mazowieckie" ["County"] => string(18)
                            "Powiat Pruszkowski" ["City"] => string(8)
                            "Brwinów" ["District"] => string(8)
                            "Brwinów" ["Street"] => string(11)
                            "ulica Rynek" ["HouseNumber"] => string(1)
                            "4" ["PostalCode"] => string(6)
                            "05-840" ["AdditionalData"] => array(3) {
                                [0] => array(2) {
                                    ["value"] => string(6)
                                    "Polska" ["key"] => string(11)
                                    "CountryName"
                                } [1] => array(2) {
                                    ["value"] => string(16)
                                    "Woj. Mazowieckie" ["key"] => string(9)
                                    "StateName"
                                } [2] => array(2) {
                                    ["value"] => string(18)
                                    "Powiat Pruszkowski" ["key"] => string(10)
                                    "CountyName"
                                }
                            }
                        }
                    }
                }
            }
        }
    }
}

}

To got array pasted above I'm using:

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$string = curl_setopt($ch, CURLOPT_URL, "https://geocoder.ls.hereapi.com/6.2/geocode.json?&street=Rynek%204&city=Brwin%C3%B3w%20&country=Poland&gen=9&apiKey=MY_API_KEY");

$result=curl_exec($ch);


curl_close($ch);

$decoded=var_dump(json_decode($result, true));

I would like to get Latitude and Longitude from DisplayPosition. How I can do this?

I tried: var_dump ($decoded[1]["Response"][0]["View"][0]["Result"][0]["Location"]["DisplayPosition"]["Latitude"]);

but it won't helpt. I think I tried everything...

It's very hard to read your array. Better show var_export($decoded). But your array starts with $decoded['Response']['View'][0]['Result'][0]... — Justinas

@mrfox And what if you do echo var_export($decoded, true);? Does your array is named $decoded? — Justinas

When I try echo var_export($decoded, true); I'm getting still NULL — mrfox

You don't get your response as an array. You get as an JSON. As I understand it you put the response in a variable you call $string (based on comments to @Sacha).

You want to treat this as an array, try doing:

//true makes the json string into an associative arrays which
//is often needed for json responses 
$array = json_decode($string, true);

When you have done this, try this:

echo '<pre>';
print_r($array);
echo '</pre>';

My guess is that it might be something like this:

$latitude = $array['Response']['View'][0]['Location']['DisplayPosition']['Latitude']
$longitudfe = $array['Response']['View'][0]['Location']['DisplayPosition']['Longitude']

But as @Sacha mentioned, you have to check value level for level to be sure that you're on the right track:

var_dump($array['Response']);
var_dump($array['Response']['View'];
var_dump($array['Response']['View'][0];

etc...

First of all I know that array is hard to read :/ I'm getting it from Here Maps service. $latitude is empty. Even when I shortened $decoded['Response']['View'][0]['Location']['DisplayPosition']['Latitude'] from you into $decoded['Response']

Aha. This is not an array. It's a JSON-formatted response.
