README
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
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 for more information on how to get started.
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
This package makes use of the mossadal/math-parser package.
