title: Populating PDF form fields with PHP
body: <p>I am converting a classic ASP application to PHP.</p>
  
  <p>In the Classic ASP app, we are programatically populating fields that have been created in PDF documents using a component called ASPpdf.</p>
  
  <p>I need to reproduce this behavior in PHP, but need to know if PHP can populate PDF fields on its own or if any third party plug in is needed.</p>
  
  <p>Is this functionlity posible in PHP with or without a plug in?</p>
  
  <p>Thanks.</p>
  
  <p>Note: I already have the PDFs created, I do not need to create the actual PDF. I need to grab a preexisting PDF with form fields, populate those form fields and then save that custom PDF.</p>
