PHP-GET URL忽略换行符

Question

Okay, so here's my problem. 好的，这是我的问题。

I have "page1.php", with following code: 我有“ page1.php”，带有以下代码：

<!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. 还有“ upload-note.php”（应将“ page1.php”中textarea的内容上载到MySQL数据库）。 For demonstration-purpose, let's just say, that it's going to echo the content of the textfield instead. 出于演示目的，我们只说它将回显文本字段的内容。

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

Now this setup works actually just fine, BUT it's ignoring linebreaks. 现在，此设置实际上可以正常运行，但是它忽略了换行符。 Any suggestions on how to handle these? 关于如何处理这些的任何建议？

The browser ignores linebreaks ( \\n ) in HTML documents. 浏览器将忽略HTML文档中的换行符（ \\n ）。 You have to change them with <br> tags like so.. 您必须像这样用<br>标签进行更改。

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

Change to POST instead of GET 更改为POST而不是GET

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

... ...

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