PHP Scripts can't find the FDF Library functions when using the ISAPI modules.


Test script:

<?php
$outfdf = fdf_create();
$volume = "test";
fdf_set_value($outfdf, "volume", $volume, 0);

fdf_set_file($outfdf, "http://localhost/webapps/volume.pdf");
Header("Content-type: application/vnd.fdf");
fdf_save($outfdf);
fdf_close($outfdf);

?>


Expected result:
----------------
A  PDF file pops up with the text fields populated with the values contained 
within the FDF file.

Actual result:
--------------
Fatal error: Call to undefined function fdf_create() in 
/opt/lampp/htdocs/sample/workingwithfdffunctions/createfdffile.php on line 20
