How to save user-entered line breaks from a TEXTAREA to a database?

When I press an ENTER KEY in a textarea it goes to newline. But when I receive this value from action page it converts to a white space. I want to receive ENTER KEY character as a newline from action page as not a white space.
Sample code : this is the HTML code

<form action="go.php" method="POST">
<textarea name="aa" cols="10" rows="10"></textarea>
<form>

Her is the go.php code :

<?php
$txt=$_POST['aa'];
echo $txt;
?>

If I input like
“this is me(PRESS ENTER KEY)this is he(PRESS ENTER KEY)”.
I want to the output as like
“this is me(newline)this is he(newline)”.
But I am getting from go.php like
“this is me this is he”.
Here is no any newline but white space.
Please anyone help me. Why it is happen.

I believe you want nl2br. This will insert HTML line breaks before all newlines in a string. If you are planning to store this in a database, you’ll need something similar to mysql_real_escape_string() to escape the line breaks.

<?php
echo nl2br("foo isn't\n bar");
?>

The HTML would look like:

foo isn't<br />
 bar

Your code would then look like:

<?php
$txt=$_POST['aa'];
echo nl2br($txt);
?>
