Function is not working in fpdf cell

Here is my code:

<?php
define('FPDF_FONTPATH','../../fpdf/font/');
require('../../fpdf/fpdf.php');
$pdf = new FPDF('L','mm','A4');
$pdf->Open();
$pdf->AddPage();

function codes($total,$mark){
    $perc = $mark/$total*100;
    if($perc >= 94){echo "A1";}    
    if($perc >= 84 && $perc<= 93){echo "A2";}
    if($perc >= 72 && $perc<= 83){echo "B1";}
    if($perc >= 60 && $perc<= 71){echo "B2";}
    if($perc >= 49 && $perc<= 59){echo "C1";}
    if($perc >= 40 && $perc<= 48){echo "C2";}
    if($perc >=0 && $perc<= 40){echo "D";}
}
$pdf->SetFont('Arial','',10);
$pdf->Ln();
$pdf->Cell(30,8,'English',1,0,'L',0,'');
$pdf->Cell(15,8,codes(25,$fa1enga),1,0,'C',0,'');

$pdf->output();

But when I run this PHP code it prints:

B2FPDF error: Some data has already been output, can't send PDF file

Please help me to show the text "B2" or whatever in fpdf cell.

Your codes function will output the result of its calculation to the client instead of returning it. For FPDF to work properly, there must not be any output at all except that from FPDF itself.

Replace all occurrences of echo in your codes function with return.
