Generate PDF at Server Side

Hi,
Pdfcrowd is cool.
And if it can generate pdf at server side, it will be cooler.
In my project, I try to implement this function:
1. fill the form in my page,
2. after submitting, the page will generate the form info into pdf, and store in the server side.

Thanks

Hello,

PDF is generated on our servers but it is possible to save it on your server.
Here is a PHP example:

<?php
    require 'pdfcrowd.php';

    // getFormHtml() is your function that generates HTML from submitted form data

    try { 
        $client = new Pdfcrowd("***", "***");
        $out_file = fopen("/path/to/fileName.pdf", "wb");
        $client->convertHtml(getFormHtml(), $out_file);
        fclose($out_file);
    }
    catch(PdfcrowdException $why) {
        echo "Pdfcrowd Error: " . $why;
    }
?>

may I ask what functionality does the getFormHtml() function performs? I am looking for a similar example that renders php variables to html and then generates pdf of it.
