Basic JSON Decode foreach loop not working php

been going at this for quite some time and I'm puzzled as to why using foreach loops does not work but the other way I show does work.

My Code:

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "http://maps.googleapis.com/maps/api/geocode/json?address=1%20The%20Strand%20Wellard");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Content-Type: application/json"
));

$response = curl_exec($ch);

$json = json_decode($response, true);

foreach ($json['results'] as $item) {
foreach ($item['geometry'] as $item2) {
foreach ($item2['location'] as $item3) {
echo $item3['lat'];
}
}
echo $item['geometry']['location']['lat'];
}

curl_close($ch);


JSON Data: https://pastebin.com/JU1wSpsD

Why doesn't echo $item3['lat']; work but echo $item['geometry']['location']['lat']; does work? If someone could help me understand why this is that would be great!

echo $item3['lat'];

echo $item['geometry']['location']['lat'];
