The phantomJS implemented require syntax (same as NodeJS )

if you want to include external library, that library is injected with module object and module.exports is the public object that the require function returns.

//myMoudle.js

var _a = 5; //this is private member of the module 

module.exports= {
    a : ()=>{
      return _a;
    },
    setA : newA=>_a=newA;
}

The require:

//someCode.js
var myModule = require('path/to/myModule')
myModule.a() //5
myModule._a //undefined
myModule.setA(6) //_a is now 6

PhantomJS docs example requiring webpage module:

var webPage = require('webpage'); //included the module https://github.com/ariya/phantomjs/blob/master/src/modules/webpage.js 
var page = webPage.create();

Included the webPage module, inside this module there's the next code

exports.create = function (opts) {
    return decorateNewPage(opts, phantom.createWebPage());
};

that allows to use webPage.create function where we used the require function
