How to get multi level array value in PHP decoded from JSON - php

Question

I am facing a problem while printing an array in PHP. I am getting data from facebook API for user events and getting the result in JSON.
I just want to get each location (City,Country). Is there any method to get them easily?
I have tried:
$myjson=json_decode($_POST['Data'],true);
echo "<pre>";
print_r($myjson["data"]);
echo "<pre>";
echo count($myjson["data"]);
echo "<pre>";
for($i =0; $i<count($myjson["data"]); $i++){
print($myjson["data"][$i]["name"]);
echo "<br />";
}
When I decode the data and use print_r:
echo "<pre>";
print_r($myjson["data"]);
I get the following result:

Answer 1

You have an array of objects, essentially. Since you're force decoding the JSON into an array you have an array of arrays.
Getting the city/country from each object in your example above is pretty simple.
foreach($myjson['data'] as $arr) {
echo $arr['place']['location']['city'], ', ', $arr['place']['location']['country'], "\n";
}
The keys mapping to place => location provide an array with the city and country keys you're looking for. So $myjson['data'][$i][place']['location']['city'] would give you the city and $myjson['data'][$i][place']['location']['country'] would give you the country, but you can iterate over $myjson['data'] with foreach more conveniently than using a for loop such as in your example above.
The first element would give you Lahore, Pakistan, for example.

Answer 2

foreach($myjson["data"] as $data){
echo $data['place']['location']['city'];
echo $data['place']['location']['country'];
}
