You can choose if you want to use the PHPRtfLite autoloader or handle loading PHPRtfLite classes on your own. In most cases you are already using a class loading strategy and just need to add PHPRtfLite to it, which is recommended. For a quick start you may use the shipped PHPRtfLite autoloader.
<?php
require_once '/path/to/your/library/PHPRtfLite.php';
// registers PHPRtfLite autoloader (spl)
PHPRtfLite::registerAutoloader();
// rtf document instance
$rtf = new PHPRtfLite();
This is a short “Hello world” example:
<?php
// rtf document instance
$rtf = new PHPRtfLite();
// add section
$sect = $rtf->addSection();
// write text
$sect->writeText('Hello world!', new PHPRtfLite_Font(), new PHPRtfLite_ParFormat());
// save rtf document to hello_world.rtf
$rtf->save('hello_world.rtf');
