PDF help

Hi Im trying to generate a PDF file using PHP. I'm taking an online tutorial.

 

I get this error when I execute:

Fatal error: Uncaught exception 'PDFlibException' with message 'Font 'Arial' with encoding 'host': Metrics data not found' in /usr/local/www/vhosts/site.co.nz/httpdocs/clientemail/pdf.php:9 Stack trace: #0 /usr/local/www/vhosts/site.co.nz/httpdocs/clientemail/pdf.php(9): pdf_findfont() #1 {main} thrown in /usr/local/www/vhosts/site.co.nz/httpdocs/clientemail/pdf.php on line 9

 

This is the code from a website:

<?php
// 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);
?>

 

What could be wrong?

 

Thanks,

Sam.
