What is the significance of declaring FPDF before the FPDF_TPL class in PHP?

Declaring FPDF before the FPDF_TPL class in PHP is significant because the FPDF_TPL class extends the FPDF class.

This ensures that the FPDF_TPL class can utilize all the functionalities provided by the FPDF class. 

require('fpdf.php');
require('fpdf_tpl.php');
