## Multi-columns

This example is a variant of the previous one showing how to lay the text across multiple columns.

`<?php define('FPDF_FONTPATH','font/'); require('fpdf.php'); class PDF extends FPDF { //Current column var $col=0; //Ordinate of column start var $y0; function Header() { //Page header global $title; $this->SetFont('Arial','B',15); $w=$this->GetStringWidth($title)+6; $this->SetX((210-$w)/2); $this->SetDrawColor(0,80,180); $this->SetFillColor(230,230,0); $this->SetTextColor(220,50,50); $this->SetLineWidth(1); $this->Cell($w,9,$title,1,1,'C',1); $this->Ln(10); //Save ordinate $this->y0=$this->GetY(); } function Footer() { //Page footer $this->SetY(-15); $this->SetFont('Arial','I',8); $this->SetTextColor(128); $this->Cell(0,10,'Page '.$this->PageNo(),0,0,'C'); } function SetCol($col) { //Set position at a given column $this->col=$col; $x=10+$col*65; $this->SetLeftMargin($x); $this->SetX($x); } function AcceptPageBreak() { //Method accepting or not automatic page break if($this->col<2) { //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 $this->SetCol(0); //Page break return true; } } function ChapterTitle($num,$label) { //Title $this->SetFont('Arial','',12); $this->SetFillColor(200,220,255); $this->Cell(0,6,"Chapter $num : $label",0,1,'L',1); $this->Ln(4); //Save ordinate $this->y0=$this->GetY(); } function ChapterBody($fichier) { //Read text file $f=fopen($fichier,'r'); $txt=fread($f,filesize($fichier)); fclose($f); //Font $this->SetFont('Times','',12); //Output text in a 6 cm width column $this->MultiCell(60,5,$txt); $this->Ln(); //Mention $this->SetFont('','I'); $this->Cell(0,5,'(end of excerpt)'); //Go back to first column $this->SetCol(0); } function PrintChapter($num,$title,$file) { //Add chapter $this->AddPage(); $this->ChapterTitle($num,$title); $this->ChapterBody($file); } } $pdf=new PDF(); $pdf->Open(); $title='20000 Leagues Under the Seas'; $pdf->SetTitle($title); $pdf->SetAuthor('Jules Verne'); $pdf->PrintChapter(1,'A RUNAWAY REEF','20k_c1.txt'); $pdf->PrintChapter(2,'THE PROS AND CONS','20k_c2.txt'); $pdf->Output(); ?>`

The key method used is AcceptPageBreak(). It allows to accept or not an automatic page break. By refusing it and altering the margin and current position, the desired column layout is achieved.
For the rest, not much change; two properties have been added to the class to save the current column number and the position where columns begin, and the MultiCell() call specifies a 6 centimeter width.
