SWFFont::__construct — Loads a font definition
$filename
)此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担 。
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");
?>
