12.2.4 Outputting Basic Text

To put text on a page, you must select the font you want to use, set the default font to be that
font at a particular size, and then add the text. For example:
$font = pdf_findfont($pdf, “Times-Roman”, “host”, 0);
pdf_setfont($pdf, $font, 48);

pdf_show_xy($pdf, “Hello, World”, 200, 200);
With PDF documents, the (0, 0) coordinate indicates the bottom-left corner of the page.

Call pdf_close( ) to complete the PDF document. If no filename was provided in the pdf_open_
file( ) call, you can now use the pdf_get_buffer( ) function to fetch the PDF buffer from memory.
To send the file to the browser, you must send Content-Type, Content-Disposition, and Content-

Demonstrating coordinates
<?php
$pdf = pdf_new( );

pdf_open_file($pdf);

pdf_set_info($pdf,”Creator”,”coords.php”);
pdf_set_info($pdf,”Author”,”ABC”);
pdf_set_info($pdf,”Title”,”Coordinate Test (PHP)”);

pdf_begin_page($pdf,612,792);

$font = pdf_findfont($pdf,”Helvetica-Bold”,”host”,0);
