Wrap Text in Fpdf in Php

Question

I am trying to Wrap a text in the Cell using FPDF. here is my code.

<?php
require('fpdf.php');

$pdf = new FPDF();

$pdf->AddPage();
$pdf->SetFont('Arial','',16);
$pdf->Cell(20,7,'Hi1',1);
$pdf->Cell(20,7,'Hi2',1);
$pdf->Cell(20,7,'Hi3',1);

$pdf->Ln();

$pdf->Cell(20,7,'Hi4',1);
$pdf->Cell(20,7,'Hi5(xtra)',1);
$pdf->Cell(20,7,'Hi5',1);

$pdf->Output();
?>

The output for this code looks like this

Now I want to Wrap that Xtra text which is there into the Cell. The xtra text should go into the second line. How should I do that.

when I use MultiCell for that line $pdf->MultiCell( 20, 7, 'Hi5(xtra)', 1); It is changing into the following..

I have tried the Answer mentioned by Log1c It came out this way

Answer 1

This automatically wrap the text into the cell by striking the font size :

class FPDF_CellFit extends FPDF
{
    //Cell with horizontal scaling if text is too wide
    function CellFit($w, $h=0, $txt='', $border=0, $ln=0, $align='', $fill=false, $link='', $scale=false, $force=true)
    {
        //Get string width
        $str_width=$this->GetStringWidth($txt);

        //Calculate ratio to fit cell
        if($w==0)
            $w = $this->w-$this->rMargin-$this->x;
        $ratio = ($w-$this->cMargin*2)/$str_width;

        $fit = ($ratio < 1 || ($ratio > 1 && $force));
        if ($fit)
        {
            if ($scale)
            {
                //Calculate horizontal scaling
                $horiz_scale=$ratio*100.0;
                //Set horizontal scaling
                $this->_out(sprintf('BT %.2F Tz ET',$horiz_scale));
            }
            else
            {
                //Calculate character spacing in points
                $char_space=($w-$this->cMargin*2-$str_width)/max(strlen($txt)-1,1)*$this->k;
                //Set character spacing
                $this->_out(sprintf('BT %.2F Tc ET',$char_space));
            }
            //Override user alignment (since text will fill up cell)
            $align='';
        }

        //Pass on to Cell method
        $this->Cell($w,$h,$txt,$border,$ln,$align,$fill,$link);

        //Reset character spacing/horizontal scaling
        if ($fit)
            $this->_out('BT '.($scale ? '100 Tz' : '0 Tc').' ET');
    }

    //Cell with horizontal scaling only if necessary
    function CellFitScale($w, $h=0, $txt='', $border=0, $ln=0, $align='', $fill=false, $link='')
    {
        $this->CellFit($w,$h,$txt,$border,$ln,$align,$fill,$link,true,false);
    }

    //Cell with horizontal scaling always
    function CellFitScaleForce($w, $h=0, $txt='', $border=0, $ln=0, $align='', $fill=false, $link='')
    {
        $this->CellFit($w,$h,$txt,$border,$ln,$align,$fill,$link,true,true);
    }

    //Cell with character spacing only if necessary
    function CellFitSpace($w, $h=0, $txt='', $border=0, $ln=0, $align='', $fill=false, $link='')
    {
        $this->CellFit($w,$h,$txt,$border,$ln,$align,$fill,$link,false,false);
    }

    //Cell with character spacing always
    function CellFitSpaceForce($w, $h=0, $txt='', $border=0, $ln=0, $align='', $fill=false, $link='')
    {
        //Same as calling CellFit directly
        $this->CellFit($w,$h,$txt,$border,$ln,$align,$fill,$link,false,true);
    }
}


$text="dfshsdbfhbsdhfbhsdbfkbfkbfkbdf";
   $this->CellFitScale(50,10,'  '.$text,1,0,'',0);//long text

Answer 2

Use MultiCell() instead Cell()

Change this:

$pdf->Cell(20,7,'Hi5(xtra)',1);

To:

$pdf->MultiCell( 20, 7, 'Hi5(xtra)', 1);

The MultiCell() is used for print text with multiple lines.

EDIT:

I can see that MultiCell(), breaks the line so new cell will be placed below current position.

In such case you can calculate x and y co-ordinate and calculate new position and set position after outputting every cell.

<?php
require('fpdf.php');

$pdf = new FPDF();

$pdf->AddPage();

$start_x=$pdf->GetX(); //initial x (start of column position)
$current_y = $pdf->GetY();
$current_x = $pdf->GetX();

$cell_width = 20;  //define cell width
$cell_height=7;    //define cell height

$pdf->SetFont('Arial','',16);

$pdf->MultiCell($cell_width,$cell_height,'Hi1',1); //print one cell value
$current_x+=$cell_width;                           //calculate position for next cell
$pdf->SetXY($current_x, $current_y);               //set position for next cell to print

$pdf->MultiCell($cell_width,$cell_height,'Hi2',1); //printing next cell
$current_x+=$cell_width;                           //re-calculate position for next cell
$pdf->SetXY($current_x, $current_y);               //set position for next cell

$pdf->MultiCell($cell_width,$cell_height,'Hi3',1);
$current_x+=$cell_width;

$pdf->Ln();
$current_x=$start_x;                       //set x to start_x (beginning of line)
$current_y+=$cell_height;                  //increase y by cell_height to print on next line

$pdf->SetXY($current_x, $current_y);

$pdf->MultiCell($cell_width,$cell_height,'Hi4',1);
$current_x+=$cell_width;
$pdf->SetXY($current_x, $current_y);

$pdf->MultiCell($cell_width,$cell_height,'Hi5(xtra)',1);
$current_x+=$cell_width;
$pdf->SetXY($current_x, $current_y);

$pdf->MultiCell($cell_width,$cell_height,'Hi5',1);
$current_x+=$cell_width;
$pdf->SetXY($current_x, $current_y);

$pdf->Output();
