i suggest to you tcpdf. it was good for me. some feature:

• no external libraries are required for the basic functions;

• all standard page formats, custom page formats, custom margins and units of measure;

• UTF-8 Unicode and Right-To-Left
  languages;

I think http://www.fpdf.org/ is the best PDF library for PHP. Download latest version from http://www.fpdf.org. Put this library folder on your root server or in your project. Create on test file named test.php & put below code in file as below.

<?php
include("fpdf/fpdf.php");
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',36);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

It will create one pdf file with contents "Hello World!" in it. You are done..
