处理即时文本框值

Is it possible to have a text input field which displays somewhere else (e.g. in a div) what its content is on change?

Example: I type 1, so 1 is outputted somewhere on my screen immediatly, then I type 2 and the previous value is now updated to 12.

html

<input type="text" id="inputField" />
<div id="screen"></div>

script

document.getElementById('inputField').onkeyup = function(){
document.getElementById('screen').innerHTML = this.value;
};

The code is good but I want the screen's inner html value to be format in php. Example: the screen value is stored into $screen and then I'd echo the output where i want into the screen

[I want (echo "$screen";) like in php I will type the number in text box means it echo the value immediately used with php format]

how to store a screen value into variable $screen
