1. First get the timestamp of the date through strtotime()
2. Get the time stamp of N days ago by "current time stamp - seconds of N days = N days ago time stamp"
3. Format conversion with date() function for the time stamp of N days ago
The date one day before the date of the date of May 1, 2012
Output: 2012-4-30
In addition, the time() function gets the timestamp of the current date!
