json_decode Usage with multi dimension JSON code

[wisam74us]

I am having proble to extract a vlaue from this code

{ "name": "1600 Amphitheatre Parkway, Mountain View, CA", "Status": { "code": 200, "request": "geocode" }, "Placemark": [ { "id": "p1", "address": "1600 Amphitheatre Pkwy, Mountain View, CA 94043, USA", "AddressDetails": {"Country": {"CountryNameCode": "US","CountryName": "USA","AdministrativeArea": {"AdministrativeAreaName": "CA","Locality": {"LocalityName": "Mountain View","Thoroughfare":{"ThoroughfareName": "1600 Amphitheatre Pkwy"},"PostalCode": {"PostalCodeNumber": "94043"}}}},"Accuracy": 8}, "ExtendedData": { "LatLonBox": { "north": 37.4251196, "south": 37.4188244, "east": -122.0809954, "west": -122.0872906 } }, "Point": { "coordinates": [ -122.0841430, 37.4219720, 0 ] } } ] }

I want to extract this value
-122.0841430

Using PHP json_decode (object or array), json_decode works fine for me with simple files but it doesnt work here for me here, any ideas?

You could try something like this. (Fast and dirty) or look into recursion instead of the nested foreach loop.

<?php
  $json = '{ 
    "name": "1600 Amphitheatre Parkway, Mountain View, CA", "Status": 
    { 
        "code": 200, "request": "geocode" 
    }, 
    "Placemark": [ 
       { 
        "id": "p1", "address": "1600 Amphitheatre Pkwy, Mountain View, CA 94043, USA", "AddressDetails": 
        {
            "Country": 
            {
                "CountryNameCode": "US","CountryName": "USA","AdministrativeArea": 
                {
                    "AdministrativeAreaName": "CA","Locality": 
                    {
                        "LocalityName": "Mountain View","Thoroughfare":
                        {
                            "ThoroughfareName": "1600 Amphitheatre Pkwy"
                        }
                        ,"PostalCode": 
                        {
                            "PostalCodeNumber": "94043"
                        }
                    }
                }
            }
            ,"Accuracy": 8
        }
        , "ExtendedData": 
        { 
            "LatLonBox": 
            { 
                "north": 37.4251196, "south": 37.4188244, "east": -122.0809954, "west": -122.0872906 
            } 
        }
        , "Point": 
        { 
            "coordinates": [ -122.0841430, 37.4219720, 0 ] 
        } 
    } 
    ] 
}';


$arr = json_decode($json, true);

foreach($arr as $key1 => $value1) {
    echo "<b>Key1: </b>" . $key1 . " <b>value1: </b>" . $value1 . "<br />";
    
    if(is_array($value1)) {
        foreach($value1 as $key2 => $value2) {
            echo "<b>Key2: </b>" . $key2 . " <b>value2: </b>" . $value2 . "<br />";
            
            if(is_array($value2)) {
                foreach($value2 as $key3 => $value3) {
                    echo "<b>Key3: </b>" . $key3 . " <b>value3: </b>" . $value3 . "<br />";
                    
                    if(is_array($value3)) {
                        foreach($value3 as $key4 => $value4) {
                            echo "<b>Key4: </b>" . $key4 . " <b>value4: </b>" . $value4 . "<br />";
                            
                            if(is_array($value4)) {
                                foreach($value4 as $key5 => $value5) {
                                    echo "<b>Key5: </b>" . $key5 . " <b>value5: </b>" . $value5 . "<br />";
                                }
                            }
                        }
