RTFLex is a simple lexer / tokenizer for RTF formatted data.

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:

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:

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:

{\rtf1\ansi\ansicpg1252\cocoartf1187\cocoasubrtf370 {\fonttbl\f0\fswiss\fcharset0 Helvetica;} {\colortbl;\red255\green255\blue255;} {\info {\title Sample Title} {\subject Sample Subject} {\author Craig Weber} {\*\company silvermine} {\*\copyright 2013 silvermine.}}\margl1440\margr1440\vieww10800\viewh8400\viewkind0 \pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\pardirnatural ... 

Using the RTFDocument class, it's easy to extract those field.

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