This script produces a customized version of the PDF document.The document, shown
in Figure 32.6, will print reliably on numerous systems, and is harder for the recipient to
modify or edit.You can see that the PDF document in Figure 32.6 looks almost exactly
like the RTF document in Figure 32.5.
One problem with this approach is that the code runs quite slowly because of the
regular expression matching required. Regular expressions run much more slowly than
str_replace() that you could use for the RTF version.
If you are going to match a large number of placeholders or try to generate many of
these documents on the same server, you might want to look at other approaches.This
issue would be less of a problem for a simpler template. Much of the bulk in this file is
data representing the images.
