CodingForums.com - 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.
