date - Display todays day of the week, month, day, year in THIS format in PHP? -

I would like to present this format of current date using PHP I have googled and found that there is some variation of what I want to do, but for the company which I want to work specifically wants to match it in this format to match.

Thank you.

If you have seen that 'D is able to understand it very easily:

  Date of Retention ('L, FJ, Y');
