Question

lets say I have bunch of hyperlinks. When link is clicked, I’d like an opened page (in a separate window) to have a google-translator style toolbox that I could use to save the page to a localdisk if I liked it, adding a few tags to the database using php. I understand how to save a file using php, but could You help me with ideas as how to add a toolbar and to send request from toolbar to my processing page?
Here’s graphic representation of my question.

Answer 1

You could have a page… say “extUrl” that contains the toolbar and an iframe where you could open the URL that your link may pass as GET parameter.

EDIT : I didn’t use php for years so the code (untested) may need debug…
your link could be something like : <a href="/extUrl.php?url=http://stackoverflow.com/">SO</a>
And your extUrl.php file would look like :

[...]
<!-- here your toolbar -->
<?php
url = $GET['url'];
?>
<iframe src="<?php echo $url ?>"></iframe>
