我需要能够从.ttf True Type字体文件中提取元数据。
我正在构建一个所有设计师都使用的所有字体的中央数据库（他们经常通过电子邮件交换字体以接管设计元素等）。 我想获取所有字体，有些字体名称很愚蠢像00001.ttf，因此文件名无法提供帮助，但我知道这些字体具有元数据，我需要一种在PHP中提取它的方法。
然后我可以创建一个循环来浏览我指定的目录，并获取这个数据（和同时获得的任何其他数据），并将其添加到数据库中。
我只是真正需要帮助读取这个元数据部分。
PHP：如何从.ttf文件中读取字体的“标题”？

有趣的问题，尽管上一个提问者没有得到答案 :( https://dev59.com/sVPTa4cB1Zd3GeqPfQOp - John Carter
我很确定可以使用ImageMagick获取字体名称，但是我似乎在ImageMagick网站上找不到任何参考。 :( - tamarintech
可能是重复的问题： PHP：读取字体文件的TrueType / OpenType元数据。 - e-sushi
也许6年前发布时它是一个重复的候选问题，但是另一个问题除了指向这里的链接之外没有真正的答案。因为另一个问题而关闭这个问题是愚蠢的。 - i-CONICA

我发现了这个链接：http://www.phpclasses.org/package/3876-PHP-Extract-information-from-TrueType-font-files.html。它可以实现你想要的功能（我已经测试过并发布了结果）。只需将TTF文件的路径传递给该类，即可解析出数据。然后使用
如果您不想注册，可以在此处找到该类。 输出的数据
$fontinfo[1].' '.$fontinfo[2]获取字体名称。如果您不想注册，可以在此处找到该类。 输出的数据

2我找到了一个链接，其中描述了TTF格式的标题结构：http://www.codeproject.com/KB/GDI/fontnamefromfile.aspx - horatio
你是不是想在原帖下面发表这个评论？ - Dutchie432
2不是真的。我的意思是发布提供有关你答案的额外信息的内容。正如发布的类显然具有文件结构的隐式信息一样，我链接的信息明确定义了标头中的字段并讨论了其中的一些内容。只是放进类很好，但对问题的更深入理解也可能会有所帮助。 - horatio
3在该代码中，“$font_tags”未定义。这个变量应该在哪里定义？它没有在任何地方声明。这对其他人是如何工作的？ - Goose

这个怎么用？在你加载类之后，你调用哪个函数并传递什么参数？ - Goose
我一开始不知道如何使用它，但在更改了一些代码后，我让它正常工作了。如果提供一个加载后如何使用该类的示例，将会对未来的访问者更有帮助。 - Goose
缺少baseClass？什么是baseClass？ - Ajit Kumar

为什么要重复造轮子呢？DOMPDF项目的优秀成员已经为您完成了工作。请查看php-font-lib @ https://github.com/PhenX/php-font-lib。它具有您所需的所有功能，并支持其他字体格式。查看演示UI @ http://pxd.me/php-font-lib/www/font_explorer.html，以了解您可以从此库中获取哪些信息的想法。

当我提出这个问题时，那还不存在。虽然现在可能有更好的方法，但我使用的答案一直为我服务得很好。 - i-CONICA
嗨，Dors！你能否给我一个使用这个库的例子？你提供的示例页面已经不存在了。顺便说一下，我投了你一票，因为这个库支持我需要的WOFF字体。 - DrupalFever
@DrupalFever，Github页面上有一个使用示例，就在项目页面https://github.com/PhenX/php-font-lib上。 - dors
