Developers get all excited about the elegence of the PHP language, and somewhere along the way they discover they have been sandbagged (they have to learn Javascipt too, if they want responsive GUI's). "One solution would be to develop a PHP Plugin and support that for all the browsers out there, but another just occurred to me. What if there was a function that accepted PHP code as input and tranlated it to Javascript, returning the resulting text ready for imbedding in html?" Nice idea, although "sandbagged" sounds like an exageration: becoming fluent in both PHP & JavaScript is hardly a major life challenge. When I finally learned PHP I was delighted at how syntactically similar it was to JavaScript, compared say to the difference between JavaScript & VBscript. Perhaps my most common mistake in writing in both PH & JS is that I tend to use . as a concatenation operator in JavaScript these days...

It would be possible to write a script which took "$a = 3" and converted it into "var a = 3", but a huge number of PHP functions either can't be implemented in Javascript (file_get_contents) or are fundamentally unsafe to implement in Javascript (mysql_query), so you'd end up with a language you couldn't do anything with." To the contrary, client-side PHP would simply be a different environment from server-side PHP -- of course certain functions wouldn't apply and others would that aren't relevant to server-side PHP, but that's not rocket science. The point would be to use the same syntax in both contexts. Relevant to this discussion, there is a set of PHP DOM functions (native to the core) that look like they match with the corresponding JavaScript functions pretty closely: http://php.net/dom I haven't used them yet, but the function names look familiar. The way I might implement such a PHP->JavaScript translation might look like this: <script type="text/javascript" src="phpToJavaScript.php?src=myscript.php"></script> where phpToJavaScript.php is the translation program and myscript.php is the "client-side PHP" script to be translated to JavaScript.
