Hello there…

<?
// create handle for new PDF document
$pdf = pdf_new();

// open a file
pdf_open_file($pdf, "philosophy.pdf");

// start a new page (A4)
pdf_begin_page($pdf, 595, 842);

// get and use a font object
$arial = pdf_findfont($pdf, "Arial", "host", 1); 
pdf_setfont($pdf, $arial, 10);

// print text
pdf_show_xy($pdf, "There are more things in heaven and earth, Horatio,", 50, 750); pdf_show_xy($pdf, "than are dreamt of in your philosophy", 50, 730);

// end page
pdf_end_page($pdf);

// close and save file
pdf_close($pdf);
?>
