UglifyPHP

UglifyPHP is a JavaScript minifier and simple obfuscator for PHP files.

How It Works

This package use a unique ID based on the current time to replace variables. You can use two minified files together and don't have to worry with variable overwriting.

This package can minify Classes and replace correctly variables and functions references with $this. It will not change any function name or create "junk code" for performance reasons.

This should not be used as a licensing or code protection solution.

Installation

  npm install uglify-php

Usage

const UglifyPHP = require('uglify-php');
 
let options = {
  "excludes": [
    '$GLOBALS',
     '$_SERVER',
     '$_GET',
     '$_POST',
     '$_FILES',
     '$_REQUEST',
     '$_SESSION',
     '$_ENV',
     '$_COOKIE',
     '$php_errormsg',
     '$HTTP_RAW_POST_DATA',
     '$http_response_header',
     '$argc',
     '$argv',
     '$this'
  ],
  "minify": {
     "replace_variables": true,
     "remove_whitespace": true,
     "remove_comments": true,
     "minify_html": false
  },
  "output": "C:/web/file_min.php" // If it's empty the promise will return the minified source code
}
 
// You can use a path or the source code
UglifyPHP.minify("C:/web/file.php", options).then(function (source) {
  console.log(source);
});

Example

Original Source Code:

<?php
  class BaseClass {
    private $name = "Uglify-PHP";
 
    function __construct() {
      $this->sayHello();
    }
 
    // Comment Block 
    public function sayHello(){
      echo "Hello " . $this->name;
    }
  }
  $obj = new BaseClass();
?> 

Minified Source Code:

<?php class BaseClass{private $j5lg3rhh="Uglify-PHP";function __construct(){$this->sayHello();}public function sayHello(){echo "Hello ".$this->j5lg3rhh;}}$j5lg3rhj=new BaseClass();?>
