How to re-build URL to make sure parameter sent - php

Question

I'm making a function that can perform queries to maps.googleapis.com. I use the library GuzzleHttp assistance.
The problem I faced is when I create a function and try to access the functionality by adding parameters in URL. Looks like this function doesn't known parameters (unallocated) consequently the function that I made did not work properly.
My Controller
public function actionGetalldata() {
$url = "https://maps.googleapis.com/maps/api/place/autocomplete/json?key=alskdsbeKASDJldkd&types=geocode&language=id&input=paci";
$client = new GuzzleHttp\Client();
$res = $client->request('GET', $url);
$data = $res->getBody();
$array = json_decode($data, true);
foreach ($array['predictions'] as $key) {
$detail = $this->getLatLong($key['place_id']);
}
}
You see... When I try to loop my whole data, I call getLatLong function but always fail because the function can not accept the parameters that I provide.
Below is the function
function getLatLong($placeid) {
$url = "https://maps.googleapis.com/maps/api/place/details/json?placeid=".$placeid."&key=alskdsbeKASDJldkd";
$client = new GuzzleHttp\Client();
$res = $client->request('GET', $url);
$data = $res->getBody();
$array = json_decode($data, true);
$resultx = $array['result'];
$id = $resultx['id'];
$placeid = $resultx['place_id'];
$alamat = $resultx['adr_address'];
$lat = $resultx['geometry']['location']['lat'];
$long = $resultx['geometry']['location']['lng'];
$allData = [
'id' => $id,
'place_id' => $placeid,
'address' => $alamat,
'lat' => $lat,
'long' => $long
];
return $allData;
}
It looks like the $placeid variable is the cause.
If I directly place a static placeid value, this function working.
How can I fix it? Please help
Thank you
