For fdf_save you need to provide the complete path, such as :fdf_save($outfdf,"c:/inetpub/wwwroot/temp_sites/fdf/outtest.fdf"); and not only outtest.fdf.
(PHP 4, PHP 5 < 5.3.0, PECL fdf SVN)

Приклад #1 Populating a PDF document
<?php
$outfdf = fdf_create();
fdf_set_value($outfdf, "volume", $volume, 0);
fdf_set_file($outfdf, "http:/testfdf/resultlabel.pdf");
fdf_save($outfdf, "outtest.fdf");
fdf_close($outfdf);
Header("Content-type: application/vnd.fdf");
$fp = fopen("outtest.fdf", "r");
fpassthru($fp);
unlink("outtest.fdf");
?>

This works for IE 5.5+
It will populate the fields and open the resulting pdf for you, without having to create an fdf file and adding the open script to the pdf...I thought the following might save someone a lot of time. The example fdf snippet above, namely:
<?php
$outfdf = fdf_create();
fdf_set_value($outfdf, "volume", $volume, 0);
fdf_set_file($outfdf, "http:/testfdf/resultlabel.pdf");
fdf_save($outfdf, "outtest.fdf");
fdf_close($outfdf);
Header("Content-type: application/vnd.fdf");
$fp = fopen("outtest.fdf", "r");
fpassthru($fp);
unlink("outtest.fdf");
?>
will not work (or there's at least a big possibility it won't) in IE (version 6 sure and I suspect lower versions as well) if you have session.auto_start on. Apparently, setting a cookie before feeding the fdf to the browser somehow messes it up. It works fine in Netscape though. I spent days on Google before I found a post somewhere about someone else having the same problem.
The solution? Well, I created a separate directory in the web tree and turned session.auto_start off just for that directory like this:
<Location /new_directory>
php_admin_flag session.auto_start 0
</Location>
Hope this was useful to somebody.Header("Content-type: application/vnd.fdf"); simply does not work in IE. The easiest method to automatically load the fdf file is to open the 'pdf' file via php. With use of Acrobat
document -> page action -> page open -> add -> javascript
and paste the following into the pdf file:
this.importAnFDF("my_fdf_file.fdf");
This will auto-load the fdf contents
