如何在使用php发送邮件时在textarea中定义ENTER

Question

I have a form that is sending as mail in php. i wanna define ENTER key in textarea content as breakline while sending it. when i type something like this :

hi

how are you?

in the inbox it shows as :

hi how are you?

please help me to fix it!

my HTML code :

<form action="mail.php" method="post">
<input type="text" name="from">
<input type="text" name="to">
<textarea name="content" rows="4" cols="40"></textarea>
</form>

my PHP code :

$to  = $_POST['to'] ;
$subject = $_POST['from'];
$message = $_POST['content'];
mail($to, $subject, $message, //$headers);

Answer 1

oops! someone answered my question but now his post is deleted!

it worked as:

$message=nl2br($_POST['content']);
