It is not possible through PHP. You have use javascript to get the values in the textbox at realtime.
But using php, you have submit the form first, and then only you will get the data on the page its submit the data too. For example as per your question, only editresultprofile.php will be able to get the data values.
On editresultprofile.php, you can do
$name = $_POST['thesubname']; //You have to change the name to what is reflected on your case
However, if you use javascript, you can get the values as they were typed, before submitting the form.
function getValues(){
var tbox = document.getElementById('yourtextboxid');
alert(tbox.value);
return false; //stop the submisison
}
Attach the function in the onSubmit event of the form.
<form onsubmit="return getValues()" >
