    Question How To Use Curl In Php For Json Results From Google Places Api

    I used my API key for querying google places API for obtaining museums around a particular place and obtained the following results in JSON form:
    {
    "html_attributions" : [],
    "results" : [
    {
    "geometry" : {
    "location" : {
    "lat" : 15.4954990,
    "lng" : 73.82120
    }
    },
    "icon" : "http://maps.gstatic.com/mapfiles/place_api/icons/museum-71.png",
    "id" : "1f1425a4048b951552591838918fddcfa92ce0a9",
    "name" : "Museum",
    "reference" : "CpQBgQAAABj0cBhH-lN_qR75O8cH-CaRqZxZyY98edwHytsuW3hEgA9YX0L9Q5lNSxxJkWKc4hQWZaBie4rAxF6toH1gfcF-EH-8aidpfccqXH7Y6UyN06gNRtaMZtX4KdoQfoDrMvcLPxlpC519Aa6ZFBWII7agaGJ8x3-4Bi7PDIH3nqe6h7ywvQFI12sXh80VE7DhuhIQ-vAeCJylozUNoeZdYEIvLRoUYjxWFbm08-HG-7RIt1JBNcCOsyI",
    "types" : [ "museum", "establishment" ],
    "vicinity" : "Althino, Panaji (Panjim)"
    }
    ],
    "status" : "OK"
    }

    Then I wrote the following code to obtain only certain data from the JSON result i.e name,type,vicinity
    Code:
    <?php
    
    $details_url = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=15.495602,73.825209&radius=500&types=museum&sensor=false&key=AIzaSyDqEa1fnjGtG4QdAiaekCHKV_tDaN4Nuxo";
    
       $ch = curl_init();
       curl_setopt($ch, CURLOPT_URL, $details_url);
       curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
       $geoloc = json_decode(curl_exec($ch), true);
    
      $name=var_dump($geoloc['results'][0]['geometry']['name']);
    $types=var_dump($geoloc['results'][0]['geometry']['types']);
    $vicinity=var_dump($geoloc['results'][0]['geometry']['types']);
    
    
       print $name;
       print $types;
         print $vicinity;
    
    ?>
    i get the following in my browser when i run the php file:
    null
    null
    null

    what do i do next? don't know what the error in the code is. i need to insert the specific data from JSON result that i have got into a database.

    You are using var_dump all wrong...Just use plain assignment(or Output buffering which is unnecessary in this case).

    PHP Code:
    $name$geoloc['results'][0]['geometry']['name'];
    $types$geoloc['results'][0]['geometry']['types'];
    $vicinity$geoloc['results'][0]['geometry']['types']; 
    Okay. Try some debugging.

    First, make sure that the cURL function is returning data. Place this code below $geoloc = json_decode(curl_exec($ch), true); Then post the results here.

    PHP Code:
    echo "<pre>";

    print_r($geoloc);

    echo 
    "</pre>"
    And make use of PHP /PHP tags and put your PHP code between them - there's even a button that does that....its mighty hard to read code like plaintext.

    case solved.
    The computer is always right. The computer is always right. The computer is always right. Take it from someone who has programmed for over ten years: not once has the computational mechanism of the machine malfunctioned.
