README

phpep is a simple expression parser written in PHP, ported from JavaScript. It can parse expressions but not operations. The difference between expressions and operations is akin to the difference between a cell in an Excel spreadsheet vs. a proper JavaScript program.

Why phpep?

I wanted a lightweight, tiny parser to be included in one of my other libraries. jsep provided this functionality. I also wanted to be able to parse these expressions in my PHP projects, which led me to porting jsep.

Usage

PHP

require('phpep.php');
$expr = new PHPEP("1 + 1");
$stack = $expr->exec();
var_dump($stack);

Custom Operators

// Not yet implemented.
