RTFLex

, _(*1)

RTFLex is a simple lexer / tokenizer for RTF formatted data., _(*2)

Example Usage

RTFLex allows you to easily extract plain text from an RTF formatted file, or a text string containing RTF formatting. Here's how you would read an RTF file:, _(*3)

require_once "rtflex/RTFLexer.php";

use RTFLex\io\StreamReader;
use RTFLex\tokenizer\RTFTokenizer;
use RTFLex\tree\RTFDocument;

$reader = new StreamReader('/path/to/myFile.rtf');
$tokenizer = new RTFTokenizer($reader);
$doc = new RTFDocument($tokenizer);
echo $doc->extractText();

While RTFLex uses namespaces to organize it's inner-workings, it also provides a simple, global, front-end class for easy of use. This accomplishes the same as the above code:, _(*4)

require_once "rtflex/RTFLexer.php";

$doc = RTFLexer::file('/path/to/myFile.rtf');
echo $doc->extractText();

RTFLex also lets you easily extract hidden metadata from an RTF file. Take, for example, the follow RTF header:, _(*5)

{\rtf1\ansi\ansicpg1252\cocoartf1187\cocoasubrtf370
{\fonttbl\f0\fswiss\fcharset0 Helvetica;}
{\colortbl;\red255\green255\blue255;}
{\info
{\title Sample Title}
{\subject Sample Subject}

...

Using the RTFDocument class, it's easy to extract those field., _(*6)

$doc = RTFLexer::file('/path/to/myFile.rtf');
echo $doc->extractMetadata('title');     // => "Sample Title"
echo $doc->extractMetadata('copyright'); // => "2013 silvermine."
