======================

A Math expression parser built in PHP.

Installation
============

[](#installation)

You can install the component by using composer.

How to use
==========

[](#how-to-use)

You can use in two ways:

- Using the ExpressionParser facade that already mount the dependecies of the Evaluator class and returns the result, like this:

```
use Parser\Facades\ExpressionParser;

$result = ExpressionParser::parse('(2+2)^(2*2)/1+3+5');

assert($result === 264);
```

- Or you can actually use you own implementation of a Lexer and/or AST by providing the dependencies to the classes, like this:

```
use Parser\Evaluator;
use Parser\Lexer; // Or your Lexer
use Parser\Syntactic; // Or your AST

$evaluator = new Evaluator(new Syntactic(new Lexer('(2+2)^(2*2)/1+3+5')));

assert($evaluator->parse() === 264);
```

Grammar
=======

[](#grammar)

The parser accepts the following operators: + ; - ; . ; \* ; / ; ^ ; ( ; )
