我真的需要能够从.ttf真实类型字体文件中提取元数据。
我正在建立一个所有设计师使用的所有字体的中央数据库（他们永远通过电子邮件交换字体以接管设计元素等）。我想得到所有的字体，有些像00001.ttf那样愚蠢的名字，所以文件名没有帮助，但我知道字体有元数据，我需要一些方法在PHP中提取它。
然后我可以创建一个循环来查看我指定的目录，获取这些数据（以及我可以同时获得的任何其他数据，并将其添加到数据库中。
我真的需要帮助阅读这个元数据部分。

我遇到了this link。它会做你想要的（我已经测试过并发布了结果）。只需将要解析数据的TTF文件的路径传递给类即可。然后使用$fontinfo[1].' '.$fontinfo[2]作为名称。
