{% codeblock info/getenv.js lang:js https://raw.github.com/kvz/phpjs/master/functions/info/getenv.js raw on github %}
function getenv (varname) {
  // From: http://phpjs.org/functions
  // +   original by: Brett Zamir (http://brett-zamir.me)
  // %        note 1: We are not using $_ENV as in PHP, you could define
  // %        note 1: "$_ENV = this.php_js.ENV;" and get/set accordingly
  // %        note 2: Returns e.g. 'en-US' when set global this.php_js.ENV is set
  // %        note 3: Uses global: php_js to store environment info
  // *     example 1: getenv('LC_ALL');
  // *     returns 1: false
  if (!this.php_js || !this.php_js.ENV || !this.php_js.ENV[varname]) {
    return false;
  }

  return this.php_js.ENV[varname];
}

Please note that php.js uses JavaScript objects as substitutes for PHP arrays, they are 
the closest match to this hashtable-like data structure. 

Please also note that php.js offers community built functions and goes by the 
[McDonald's Theory](https://medium.com/what-i-learned-building/9216e1c9da7d). We'll put online 
functions that are far from perfect, in the hopes to spark better contributions. 
Do you have one? Then please just:
