title: XSL-FO processor for PHP : transform XML to PDF
body: <p>I am looking for a PHP XSL-FO processor.</p>
  
  <p>What I need is an alternative to <a href="http://xmlgraphics.apache.org/fop/" rel="noreferrer">Apache FOP</a> (in the Java world), in order to convert an XML document to PDF, but I need to execute it in a PHP environment without Java support.</p>
