title: Generate NACHA file using PHP?
body: <p>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 <em>probably</em> 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.</p>
  
  <p>I have searched around Google pretty hard unsuccessfully so any assistance is appreciated.</p>
  
  <p>Thank you for your time.</p>
