PHP script to call API, Sum/Count items, then send email

I need a PHP script that will: #1. Issue an API call and capture the return JSON response. #2. Sum ONE of the fields in each JSON “record”. #3. Count how many JSON “records” there are. #4. Send an email that says “This is the count” and then include the Sum from #2 above, and “This is how many records there are” then include the Count from #3 above. I will end up setting up this script as a CRON job that runs every day. DETAILS: For #1: I have tested and I am able to issue the API call via [login to view URL] and capture the returning JSON response. So I know the call works, and I can see the JSON response. When you build the script, you will have to change two variables (that control the date range of the request) in the API request every time the script runs. The starting date will be the CURRENT SYSTEM date and the ending date will be the CURRENT SYSTEM DATE plus 30 days. For #2. I have included a sample of the JSON response as an attachment (a 3 day range). The “field” that I am interested in summing for each record is the “number” field. IMPORTANT: The API will only let you retrieve 31 days of data, but I want 90, so you must issue the API call 3 times to get 90 days of data, and them sum across the 3 requests. For #3. Count the records. You can do this yourself, OR it is in the bottom of the API JSON response as “totalItems”. #4. Send an email via PHP to an email address. In the formatted email, “reservations” is the “number” (that you are summing) and “bookings” is the count of the records. See a sample of the email as an attachment. Finally, you will need to comment your code, so that if I need to make small changes in the future, I can understand what you are doing.
