This is your problem:
$maps_url = 'https://maps.googleapis
.com/maps/api/geocode/json?address='.
urlencode($_GET['location']);
You have an address with a new line character (and some spaces) in it. This is what the address looks like when you pass it to file_get_contents() :
'https://maps.googleapis\n .com/maps/api/geocode/json?address='
You can fix this by either splitting it into two strings or putting it on one line:
$maps_url = 'https://maps.googleapis' .
'.com/maps/api/geocode/json?address='.
urlencode($_GET['location']);
The instagram URL suffers from the same problem.

WhenI was copy and pasting code there was a typo in the uri. It was missing an equal sign for the lat key value pair

Instagram has changed its api. You cannot use the client_id in the endpoint anymore. Instead you have to request for authentication, receive the access token and pass this access token instead of client_id.
Here's the link for the instagram developer API https://www.instagram.com/developer/endpoints/media/
