I have been playing with bookmarklets and made one that wraps a page in an iframe
then puts a form so I can submit data to my server but I can't get PHP variables from the page.
sample code (have been compiling to bookmarklet at: http://moxleystratton.com/javascript/bookmarklet-compiler):
javascript:void((function(){
var a=document;
a.write(
'<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>'+a.title+' - Edit Mode </title>
</head>
<body>
<section>
<div id="wrapper">
<iframe src="'+a.URL+'" >
</iframe>
</div>
</section>
<footer>
<form action="/sys/manage/seo.php" method="post">
<input type="hidden" value=rawData >
<label for="title">Title</label>
<input type="text" name="title" value="<?= $title;?>">
<label for="title">Meta-Description</label>
<input type="text" name="meta-desc" value="<?= $data->meta-desc;?>">
<label for="title">Meta-Keywords</label>
<input type="text" name="meta-key" value="<?= $data->meta-key;?>">
</form>
</footer>
</body>
</html>')})());
