This PHP package provides a `math_eval` helper function, that allows safe evaluation of mathematical expressions, without the use of the potentially dangerous `eval` function.

Installation
------------

[](#installation)

The `math_eval` package can be easily installed using Composer. Just run the following command from the root of your project.

```
composer require "langleyfoxall/math_eval"

```

If you have never used the Composer dependency manager before, head to the [Composer website](https://getcomposer.org/) for more information on how to get started.

Usage
-----

[](#usage)

To evaluate a basic mathematical expression, just pass its string representation to the `math_eval` function.

Here are some basic usage examples:

```
$two = math_eval('1 + 1');
$three = math_eval('5 - 2');
$ten = math_eval('2 * 5');
$four = math_eval('8 / 2');
```

It is also possible to pass expression variables. See the examples below.

```
$ten = math_eval('a + b', ['a' => 7, 'b' => 3]);
$fifteen = math_eval('x * y', ['x' => 3, 'y' => 5]);
```

Credit
------

[](#credit)

This package makes use of the [`mossadal/math-parser`](https://github.com/mossadal/math-parser) package.
