# SWFFont::__construct

Loads a font definition

### Description

SWFFont::__construct ( string `$filename` )
Warning

This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk.

If `filename` is the name of an FDB file (i.e., it ends in ".fdb"), load the font definition found in said file. Otherwise, create a browser-defined font reference.

FDB ("font definition block") is a very simple wrapper for the SWF DefineFont2 block which contains a full description of a font. One may create FDB files from SWT Generator template files with the included makefdb utility- look in the util directory off the main ming distribution directory.

Browser-defined fonts don't contain any information about the font other than its name. It is assumed that the font definition will be provided by the movie player. The fonts _serif, _sans, and _typewriter should always be available. For example:

`<?php
$f = newSWFFont("_sans");
?>`
will give you the standard sans-serif font, probably the same as what you'd get with <font name="sans-serif"> in HTML.
