How to divide page in two column FPDF - php

Question

I want to divide page in to two column using FPDF. I am using below code which created pdf in two cloumn but issue is that the gap is some bit more between column. I want to reduce gap between the column only.
My code here
class PDF extends FPDF
{
protected $col = 0; // Current column
protected $y0; // Ordinate of column start
function Header()
{
}
function Footer()
{
}
function SetCol($col)
{
// Set position at a given column
$this->col = $col;
$x = 10+$col*50;
$this->SetLeftMargin($x);
$this->SetX($x);
}
function AcceptPageBreak()
{
if($this->col<2)
{
// Go to next column
$this->SetCol($this->col+2);
// Set ordinate to top
$this->SetY($this->y0);
// Keep on page
return false;
}
else
{
// Go back to first column
$this->SetCol(0);
// Page break
return true;
}
}
function ChapterBody($file)
{
$txt = file_get_contents($file);
$this->SetFont('Times','',12);
$this->MultiCell(100, 7, $txt);
$this->Ln();
$this->SetCol(0);
}
function PrintChapter($num, $title, $file)
{
// Add chapter
$this->AddPage();
$this->ChapterBody($file);
}
}
$pdf = new PDF();
$title = '20000 Leagues Under the Seas';
$pdf->SetTitle($title);
$pdf->SetAuthor('Jules Verne');
$pdf->PrintChapter(1,'A RUNAWAY REEF','20k_c1.txt');
$pdf->Output();

You are skipping to third column. See bellow with two columns per page:
function AcceptPageBreak()
{
if($this->col<1)
{
// Go to next column
$this->SetCol($this->col+1);
// Set ordinate to top
$this->SetY($this->y0);
// Keep on page
return false;
}
else
{
// Go back to first column
$this->SetCol(0);
// Page break
return true;
}
}
