The libraries and frameworks mentioned here are good, but if all you want to do is fill in a form and flatten it, I recommend the command line tool called pdftk (PDF Toolkit).,The pdftk command can generate an FDF file from a PDF form file.

PDFtk uses FDF files for manipulating PDF forms, but what is an FDF file? ,PDFtk provides a wide variety of features for manipulating PDF documents, from merging and splitting pages to filling out PDF forms, or even applying watermarks. This article focuses on using PDFtk to fill out a standard PDF form using PHP.,This section is also the same for all of our FDF files.,We installed PDFtk and learned some of its useful commands like dump_data_fields and fill_form. Then, we created a basic class around it, to show how we can bring PDFtk’s power to our PHP applications.

Once the VM is booted up, and we’ve managed to ssh into the system with vagrant ssh, we can start installing PDFtk using apt-get:

sudo apt - get install pdftk

        $data = "%FDF-1.2\n%����\n1 0 obj\n<< \n/FDF << /Fields [ "; foreach ($info as $field => $val) {
            if (is_array($val)) {
                $data.='<</T(' . $field . ')/V['; foreach ($val as $opt) $data.='(' . trim($opt) . ')'; $data.=']>>';
            } else {
                $data.='<</T(' . $field . ')/V(' . trim($val) . ')>>';
            }
        }
