网页抓取 - 无法获取网页源代码

I want to get page source of one website, is it ok to put the address of that website? Im using PHP for scrapping, the problem is that I can't get the page source code, I also tried with phantomjs, I call this script from my PHP code:

var system = require('system');
var args = system.args;

if (args.length === 1) {
  console.log('Try to pass some arguments when invoking this script!');
} 
else {
    var page = require('webpage').create();
    page.settings.userAgent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.2062'
    page.open(args[1], function(status) {
        page.onLoadFinished = function(status){
            console.log(page.content);
            phantom.exit();
        };
    });
}

but every time I receive only empty page, I try also with luminati proxy but it does not work, does someone have an idea what else I can try?
