SMS reminders Using Amazon SNS

Getting Started

1. If you haven't already, you'll want to sign up for AWS and SNS.
2. Head over to your IAM console, add a user called "sns-reminders", with "Programmatic access" is checked, attaching the policy AmazonSNSFullAccess and get the Access key ID and Secret access key.
3. Create a new topic with {'name':'sns-reminders', 'Display Name':'REMINDERS'} and then subscribe your mobile number to that topic. Get the topic details "Topic ARN" and "Region".
4. create a credentials file at ~/.aws/ and chmod 600 credentials, and then you can copy and paste the aws_access_key_id and aws_secret_access_key to replace their placeholders in your ~/.aws/credentials file.

[sns-reminders]
aws_access_key_id = YOUR_AWS_ACCESS_KEY_ID
aws_secret_access_key = YOUR_AWS_SECRET_ACCESS_KEY

5. Now let's send our first message! Open the project folder in your command line and type the following command:

    $ php send.php "Walk your dogs now!"

6. Cron Your Way to Good Habits

    $ crontab -e
     0  10  *   *   *   php ~/sns-reminders/send.php "Walk your dogs now!" >> ~/sns-reminders/cron.log 2>&1
