Generate NACHA file using PHP? [closed]

Question

I am trying to generate a bank NACHA (national automated clearing house association) file with my customers payment details to submit to my bank on a regular basis. Our site is built in PHP and though we could probably build the file ourselves, I was curious if anybody knew of any existing scripts or even reference guides for others who have done so using PHP.

I have searched around Google pretty hard unsuccessfully so any assistance is appreciated.

Thank you for your time.

I also needed such a thing... didn't find one so I made one.
