Mysterious PHP command

I am looking for a detailed procedulre for using -> in PHP.

I know it is used somehow in the calling of functions and assigning variables? but I cannot find docs on it anywhere.

Example would be.

$This->sql

or something like that.

Thanks

<?php
require('fpdf.php');
// function definitions ----------------------------------------------
class PDF extends FPDF
{
//Page header
function Header()
{
//Logo
$this->Image('logo_pb.png',10,8,33);
//Arial bold 15
$this->SetFont('Arial','B',15);
//Move to the right
$this->Cell(80);
//Title
$this->Cell(30,10,'Title',1,0,'C');
//Line break
$this->Ln(20);
}

//Page footer
function Footer()
{
//Position at 1.5 cm from bottom
$this->SetY(-15);
//Arial italic 8
$this->SetFont('Arial','I',8);
//Page number
$this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C');
}

$pdf=new PDF();
$pdf->AliasNbPages();
$pdf->AddPage();
$pdf->SetFont('Times','',12);
for($i=1;$i<=40;$i++)
$pdf->Cell(0,10,'Printing line number '.$i,0,1);
$pdf->Output();
