Replace 'file_get_contents()' with cURL

[sparky672]

My hosting company, for security reasons, is forcing PHP setting allow_url_fopen to FALSE, thereby disabling file_get_contents() in the get_lat_long_from_address() function. This forces a total failure of the geocoding function, which then only returns 0,0 for Lat/Lng, thereby setting all maps in the middle of the ocean off the western coast of Africa.

The only solution, other than new hosting, was to replace the file_get_contents() line with cURL as per the following.

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $data_location);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);

$data = json_decode($output);

Secondly, due to constant JavaScript warnings, I've removed all traces of the obsolete sensor parameter as per recommendation by Google:

Finally, I've set the default value for the $https variable to TRUE as per recommendation by Google:
