PHP Math Tokenizer

Mathematicator Tokenizer is a simple library for converting string math formulas to a stream of tokens with LaTeX support.

Installation

composer require mathematicator-core/tokenizer

Features

• Convert all your math formulas to a stream of tokens
• Convert user math input to LaTeX
• Render the tokens tree map for debug

Usage

Inject the Tokenizer service via DI and tokenize your query.

use \Mathematicator\Tokenizer\Tokenizer;

$tokenizer = new Tokenizer(/* some dependencies */);

// Convert math formula to an array of tokens:
$tokens = $tokenizer->tokenize('(5+3)*(2/(7+3))');

// Now you can convert tokens to a more useful format:
$objectTokens = $tokenizer->tokensToObject($tokens);

var_dump($objectTokens); // Return typed tokens with meta data

// Render to LaTeX
echo $tokenizer->tokensToLatex($objectTokens);

// Render to debug tree (extremely fast):
echo $tokenizer->renderTokensTree($objectTokens);

Configuration

The tokenizer uses automatic configuration based on DI. Just use the DI container and the service will be fully available.

Mathematicator Framework tools structure

The biggest advantage is that you can choose which layer best fits your needs and start build on the top of it, immediately, without the need to create everything by yourself. Our tools are tested for bugs and tuned for performance, so you can save a significant amount of your time, money, and effort.

Framework tend to be modular as much as possible, so you should be able to create an extension on each layer and its sublayers.
