Different JSON responses - {"count":"123"} vs {"count"=>"123"} - php

Question

I have some PHP code which queries a MySQL database for a count.
When queried via a browser I get the following output:
{"count":"123"}
I also have a Ruby script which executes the same PHP script via Net::HTTP but the output is different:
{"count"=>"123"}
Why is this?
//The URL
uri = URI.parse("http://lab/count.php")
http = Net::HTTP.new(uri.host, uri.port)
//Request URL
request = Net::HTTP::Get.new(uri.request_uri)
//Basic authentication
request.basic_auth("user1", "secret")
response = http.request(request)
//Response
response = JSON.parse(response.body)
puts results
//Value 'count'
count = JSON.parse(response.body)[0]
puts count
Thanks.

{"count"=>"123"} is not JSON response.
It's ruby literal for Hash table.
I think you are seeing the result of parsed JSON:
>> require 'json'
>> JSON.parse('{"count":"123"}') # => {"count"=>"123"}
>> puts JSON.dump({"count"=>"123"}) # prints => {"count":"123"}
UPDATE response to comment
To get 123 printed.
uri = URI.parse("http://lab/count.php")
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Get.new(uri.request_uri)
request.basic_auth("user1", "secret")
response = http.request(request)
response = JSON.parse(response.body)
puts response['count']
