 php

$fileData = $file->getRawData();
// Do anything you like with data string.

 php
$file = new File('path/to/my/file.txt');
//Read bytes 10-100 inclusive
$file->read(10, 100);

$fileData = $file->getRawData();

 php 
$file = new File('path/to/my/new/file.txt');

//The method File::create() is used to create new files
$file->create();

 php 
$file = new File('path/to/my/old/file.txt');
$file->setRawData('Hello');

//Setting raw data before each call to the method File::write() will append to file.

//By supplying true as parameter to the method File::write(), the old content of the file will be overridden.

$file->setRawData($encodedData, true);

//$decoded is now the string 'Hello World!'
//By supplying true as second parameter to the method File::setRawData(), the method will decode given data

 php

//$encoded is now the string 'SGVsbG8gV29ybGQh'
//By supplying true as second parameter to the method File::getRawData(), the method will encode given data
