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
<?php
$phantom_script= dirname(__FILE__). '/get-website.js';
$response = exec ('phantomjs ' . $phantom_script);
echo htmlspecialchars($response);
?>
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
<?php
$html=file_get_contents('http://google.com');
echo $html;
?>
