Here is how I added a dashed line to my pdf.  I couldn't find any info on this, so I decided to write what I learned from trial and error.

On a page that is 612px wide and signified by $p, I drew a dashed line from left to right.
$p = pdf_new();
pdf_begin_document($p,"","");
pdf_begin_page_ext($p,612,792,"");

pdf_setdash($p,3,7);      //3,7 can be any set of numbers
pdf_save($p);                //This saves what already there
pdf_moveto($p,0,700);  //move the pointer here
pdf_lineto($p,612,700);      //draw a line
pdf_closepath_stroke($p);  //show the line
pdf_restore($p);              //put it all back

pdf_end_page_ext($p,"");
pdf_end_document($p,"");

$buf = pdf_get_buffer($p);
$len = strlen($buf);
header("Content-type: application/pdf");
header("Content-Length: $len");
header("Content-Disposition: inline; filename=hello.pdf");
print $buf;
