Jason,
While theoretically it will work to access a font file this way, it will
only do so if the font file is accessible from the web; you won't be
able to place it in a directory outside of your web site (which is
really a better idea anyway). Additionally, when such an operation does
work, it requires an extra request to the web server, unnecessarily
increasing server load.
A much better way to access files on your server (and not just .ttf
files - it works for other files you wish to include, also) is to make
it relative to the root directory of your web site *on the file system*.
You could hard code this, but then you have to change it every time you
move the site to a new directory, change hosting companies, go from your
development machine to your production one, etc. Fortunately, there is
a value in the $_SERVER superglobal array which helps here.
Use $home=$_SERVER['DOCUMENT_ROOT'];
This will set $home to the root directory of your web server on the
disk. You can now access your file with:
$f_font = "$home/arialbd.ttf";
Or, even better, since this would not normally be accessed from the web
and if your web hosting company allows you to place files below the
websites root directory, you can place the file 1 level down, i.e. if
your web sites's home directory is /var/www/example/html, you could
place the file in /var/www/example and access it with
$f_font = "$home/../arialbd.ttf";
Or even in a subdirectory of it with
$f_font = "$home/../fonts/arialbd.ttf";
