date ，Y，strtotime（$ input））

I am pulling the dates of various posts from a database. The dates are in the following format:

2009-08-12

Numeric Year - Numeric Month - Numeric Day

How can I reformat these dates to something more user friendly like:

August 12, 2009

Numeric Month Numeric Date, Numeric Year

Assuming that the date gotten from the mysql database is stored in a variable called:

$date = $row['date_selected'];

date("F d, Y", strtotime($input))
