phpep: A Tiny PHP Expression Parser - Ported from jsep
------------------------------------------------------

[](#phpep-a-tiny-php-expression-parser---ported-from-jsep)

[phpep](http://jsep.from.so/) 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?

[](#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

[](#usage)

#### PHP

[](#php)

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

```

#### Custom Operators

[](#custom-operators)

```
// Not yet implemented.

```

### Install dependencies

[](#install-dependencies)

### PHPUnit Tests

[](#phpunit-tests)

### License

[](#license)

phpep is under the MIT license. See LICENSE file.

### Thanks

[](#thanks)

Thanks to Stephen Oney for the original jsep project Some parts of the latest version of jsep were adapted from the esprima parser.
