<?php
 
use setasign\Fpdi;

require_once('tcpdf/tcpdf.php');
require_once('fpdi/autoload.php');
 
// initiate PDF
$pdf = new Fpdi();
$pdf->SetMargins(PDF_MARGIN_LEFT, 40, PDF_MARGIN_RIGHT);
$pdf->SetAutoPageBreak(true, 40);



$pagecount  = $pdf->setSourceFile('a.pdf');

for($i=1; $i<=$pagecount; $i++){ 
    $pdf->addPage(); 

    $tplId =  $pdf->importPage($i);
    $pdf->useTemplate($tplId);
 

	$pdf->SetTextColor(255,0,0);	
	
	$pdf->SetXY(55,27); 
	$pdf->Cell(30, 0, "test", 0, $ln=0, 'C', 0, '', 0, false, 'T', 'L');

	
}

$pdf->Output('output.pdf', 'I');
