I Can't get it to work. It is complicated to describe the whole project since it's 10 files php only.
If you could get this to work i would really appreciate it.

JavaScript

function getText() {
	var $a =	document.getElementById('text').value;
		xhr = new XMLHttpRequest();
		xhr.open('POST' , 'chatdb.php',true);
		xhr.setRequestHeader('content-type','application/x-www-form-urlencoded');
		xhr.send('chat='+$a);
		xhr.onreadystatechange=function(){
			if (xhr.responseText){
			//	document.getElementById('chatarea').innerHTML=xhr.responseText;
									}
				}
}

What I have tried:

I've tried this:

JavaScript

function getText(){
    var a =	document.getElementById('text').value;
    fetch ('chatdb.php', {method: 'post'})
        .then (response => response.text())
        .then (responseText => {
            document.getElementById('text').innerHTML = responseText;
        })
        .catch (console.error);
}

"it's 10 files php only"
So why have you tagged it JavaSE6?

Your code is javascript and not php.

You're not sending the POST data:

JavaScript

function getText(){
    var a = document.getElementById('text').value;
    fetch ('chatdb.php', {
        method: 'POST',
        headers: { "Content-Type": "application/x-www-form-urlencoded" },
        body: "chat=" + encodeURIComponent(a)
    })
    .then (response => response.text())
    .then (responseText => {
        document.getElementById('text').innerHTML = responseText;
    })
    .catch (console.error);
}
