# pdf_open_file

(PHP 4 >= 4.0.5)

pdf_open_file -- Opens a new pdf object

## Description

``int pdf_open_file` (int pdf object [, string filename])`

Create a new PDF file using the supplied file name. If `filename` is empty the PDF document will be generated in memory instead of on file. The result must be fetched by the client with the pdf_get_buffer() function.

The following example shows how to create a pdf document in memory and how to output it correctly.

Example 1. Creating a PDF document in memory
    <?php

    $pdf = pdf_new();

    pdf_open_file($pdf);
    pdf_begin_page($pdf, 595, 842);
    pdf_set_font($pdf, "Times-Roman", 30, "host");
    pdf_set_value($pdf, "textrendering", 1);
    pdf_show_xy($pdf, "A PDF document created in memory!", 50, 750);
    pdf_end_page($pdf);
    pdf_close($pdf);

    $data = pdf_get_buffer($pdf);

    header("Content-type: application/pdf");
    header("Content-disposition: inline; filename=test.pdf");
    header("Content-length: " . strlen($data));

    echo $data;

    ?>
