Answer 1

Update 2 Adds more details on how to use phantomjs from PHP.

Update 1 (after clarification that javascript on target page need to run first)

Method 1:Use phantomjs(will execute javascript);

1. Download phantomjs and place the executable in a path that your PHP binary can reach.

2. Place the following 2 files in the same directory:

get-website.php

get-website.js

var webPage = require('webpage');
var page = webPage.create();

page.open('http://google.com/', function(status) {
 console.log(page.content);
  phantom.exit();
});

3. Browse to get-website.php and the target site, http://google.com contents will return after executing inline javascript. You can also call this from a command line using php /path/to/get-website.php.

Method 2:Use Ajax with PHP (No phantomjs so won't run javascript);

/get-website.php

test.html
