What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



fdf_save — Writes out the FDF file.


bool fdf_save(fdfdoc, filename);
resource fdfdoc: FDF document identifier
string filename: File name


TRUE on success; FALSE on error


The fdf_save() function saves an FDF document. The FDF Toolkit provides a way to output the document to stdout if the parameter filename is '.'. This doesn't work if PHP is used as an Apache module. The normal method is to write to a file and use fpassthru() to output the FDF file.


Existing since versions 3.0.6 and 4.0


Example 283. Create an FDF file

// create an FDF
$outfdf = fdf_create();

// set a field value
fdf_set_value($outfdf, "volume", $volume, 0);

// set the results file
fdf_set_file($outfdf, "http://testserver/testfdf/results.pdf");

// save the output file
fdf_save($outfdf, "outtest.fdf");

// display to client
Header("Content-type: application/vnd.fdf");
$fp = fopen("outtest.fdf", "r");
