fetch dynamically modified html content from page using ob_start and ob_get_clean()

Question

Here's the situation. I need to fetch a page and execute the javascript.. then process the page in PHP. That javascript dynamically modifies the HTML of the page. Here's what I'm thinking of doing.

• 1) Fetching the content using cURL/file_get_contents.
• 2) Print the content so that Javascript gets executed.
• 3) Use ob_start and ob_get_clean to fetch the modified content.

Code:

$contents = file_get_contents('http://...');
ob_start();
echo $contents;
$output = ob_get_clean();

Is there a way to achieve what I am attempting to do? I know javascript usually executes after page has loaded (and PHP is long gone).

带有.ajax() jQuery或带有纯JavaScript的XMLHttpRequest对象。
