PHP - Google Places Api

For every search, I get ZERO RESULTS, and I don't understand what I'm doing wrong.

Code: [Select]
<?php
require('places_class.php');

$types = $_POST['type'];
$location = $_POST['place'];
$radius = $_POST['radius'];

$gplaces = New GooglePlaces;
$gplaces->SetLocation("$location");
$gplaces->SetRadius($radius);
$gplaces->SetTypes("$types");
$results = $gplaces->Search();

print_r($results);
?>

That's when the form is submitted, I checked the variables, and they are echoing out correctly.

Then I thought I'd hard-code the values in, same results
Code: [Select]
<?php
require('places_class.php');

$gplaces = New GooglePlaces;
$gplaces->SetLocation("40.5267,81.4778");
$gplaces->SetRadius(50);
$gplaces->SetTypes("food");
$results = $gplaces->Search();

print_r($results);
?>

Here is the class
Code: [Select]

And yes, I do have the correct API Key, I just took it out

Can anybody see what the issue is?
