我真的需要能够从 .ttf 真字体文件中提取元数据。

我正在为我们所有设计师使用的所有字体构建一个中央数据库(他们总是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，有些名字很傻，比如 00001.ttf，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(以及我可以同时获取的任何其他数据，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。

最佳答案

我遇到了this link .它会做你想做的(我已经测试过它并发布了结果)。只需将要从中解析数据的 TTF 文件的路径传递给类。然后使用 $fontinfo[1]。' '.$fontinfo[2] 为名称。

如果你不想注册，这里是类(class)

用法

<?php 
    include 'ttfInfo.class.php'; 
    $fontinfo = getFontInfo('c:\windows\fonts\_LDS_almosnow.ttf'); 
    echo '<pre>'; 
    print_r($fontinfo); 
    echo '</pre>'; 
?>
