PHP: How to read "Title" of font from .ttf file?

Question

I really need to be able to extract the metadata from a .ttf true type font file.

I'm building a central database of all the fonts all our designers use (they're forever swapping fonts via email to take over design elements, etc). I want to get all the fonts, some have silly names like 00001.ttf, so file name is no help, but I know the fonts have metadata, I need some way to extract that in PHP.

Then I can create a loop to look through the directories I've specified, get this data (and any other data I can get at the same time, and add it to a database.

I just really need help with the reading of this metadata part.

Answer 1

I came across this link. It will do what you want (I've tested it and posted results). Just pass the class the path of the TTF file you want to parse the data out of. then use $fontinfo[1].' '.$fontinfo[2] for the name.

In case you don't want to register, here is the class

Resulting Data

Array (     [1] => Almonte Snow     [2] => Regular     [3] => RayLarabie: Almonte Snow: 2000     [4] => Almonte Snow     [5] => Version 2.000 2004     [6] => AlmonteSnow     [8] => Ray Larabie     [9] => Ray Larabie     [10] => Larabie Fonts is able to offer unique free fonts through the generous support of visitors to the site. Making fonts is my full-time job and every donation, in any amount, enables me to continue running the site and creating new fonts.

Usage

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

Very similar to the previously posted answer... I've been using this class for a long time now.
