PHP - GET url忽略换行符

Okay, so here's my problem.

I have "page1.php", with following code:

<!DOCTYPE html>
<html>
    <head>
        <script src="https://code.jquery.com/jquery-1.10.2.js"></script>
    </head>
<body>

<textarea id="note-textarea"></textarea>

<script>
    $( "#note-textarea" ).keyup( function() {
            $( "#output_div" ).html( $( this ).val() );


    setTimeout(function () {
            var xmlhttp;
            if(window.XMLHttpRequest){
                xmlhttp = new XMLHttpRequest();
            }else{
                xmlhttp = new ActiveXObject("XMLHTTP");
            }


            xmlhttp.open("GET", "/upload-note?note="+$('#note-textarea').val(), true);
            xmlhttp.send(null);
        }, 1000);

    });
</script>

</body>
</html>

And "upload-note.php", which should upload the content of the textarea from "page1.php", to a MySQL database. For demonstration-purpose, let's just say, that it's going to echo the content of the textfield instead.

<?php
    echo($_GET['note']);
?>

Now this setup works actually just fine, BUT it's ignoring linebreaks. Any suggestions on how to handle these?

    The browser ignores linebreaks ( ) in HTML documents. You have to change them with <br> tags like so..

    echo nl2br($_GET['note']);
    

    Change to POST instead of GET

    xmlhttp.open("POST", "/upload-note", true);
    xmlhttp.send("note="+$('#note-textarea').val());
    

    ...

    echo nl2br($_POST['note']);
