What permissions need to be set for TTF files when using ImageTTFText in PHP?

When using ImageTTFText in PHP to work with TrueType font (TTF) files, the TTF files need to have the appropriate read permissions set in order for PHP to access and use them. Typically, the TTF files should have read permissions set for the user running the PHP script, which can be achieved by setting the file permissions to 644.

// Set the correct permissions for TTF files
chmod('/path/to/font.ttf', 0644);
