If all 3 pages are in effect refreshing, only index.php needs to know what is going on. Index.php tells the iframe pages that the url to load in the scr is.

<?php
echo '<iframe src=iframe-a.php?search=' . $string_passed_to_index.php . '>';

[That way you only have to sanitize it once.] No, bad Cups! I take that bit back.

You need to use JavaScript for this. Attach some code to the onClick event of the link and refresh both iframes manually.

Edit: Something like this (using jQuery)

$('a#your-link-id').click(function(event) {
    event.preventDefault();
    $('#iframe-a').attr('src', 'iframe-a.php?search=something');
    $('#iframe-b').attr('src', 'iframe-b.php?search=something');
});

Note: Set the proper id attributes in your HTML.

This is a client problem. PHP don't know anything about iframes or targets. It only processes HTTP requests.
