如何在TCPDF中添加脚注？

I'm using TCPDF library and I want to add footnotes.

How can I do this from code? Is there a "shortcut" or should I just edit the Footer() function?

You should use the footer function like for example:

class PDF extends TCPDF {
    public function Footer() {
        $this->Cell(0, 10, 'Some footer text');
    }
}
