Generating Javascript from PHP?

Question

Are there any libraries or tools specifically designed to help PHP programmers write Javascript? Essentially, converting the PHP logic into Javascript logic. For instance:

$document = new Document($html);
$myFoo = $document->getElementById("foo");
$myFoo->value = "Hello World";

Being converted into the following output:

var myFoo = document.getElementById("foo");
myFoo.value = "Hello World";

So the $html that is passed in won't initially be modified by the PHP. Instead, the PHP will convert itself into Javascript which is then appended onto the end of the $html variable to be ran when the variable it output and converted into the client-side DOM.

Of course it would be excellent if more complicated solutions could be derived too, perhaps converting objects and internal methods into javascript-objects, etc.

Answer 1

Why would you want to do this?

Generally you want to do in PHP things you want to run on the server, and in JS things you want to do on the client (user's) machine.

However if you really want to, check out this http://phpjs.org/

php.js is an open source project that brings high-level PHP functions to low-level JavaScript platforms such as web browsers ...

Answer 2

Sounds like you may be looking for something like http://xajaxproject.org. However, it might be geared more towards ajax functionality.. not all javascript. I toyed with it about 2 years ago but never used it seriously. Might be worth a look.
