PHP-Font-Parser

A PHP OpenType font parser, capable of extracting glyphs from TrueType and CFF OpenType fonts. TrueType collections are not supported (yet).

Have a look at fonttest.php to see an example on how to use this package.

:warning: Note: this project hasn't been actively maintained in almost a decade. If you still use this, and have problems with modern PHP, fixing that is going to be more work than I can justify spending on this, so you'll need to help out.
