How to send a data '\n' using curl post in php?

Question

I am sending same data with PHP cURL. But I am using "\\n" character in a text area and it prints "Empty reply from server" . Unless I use "\\n", it is working.

For example:

<form action="gonder.php" method="post">
<textarea name="content" rows=23 cols=70></textarea>
<input class="button" type="submit" value="Kaydet">
</form>

And my gonder.php file:

<?php

if($_POST['content'] != ""){

$ch = curl_init('http://address/page.php');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'bilgi='.$_POST['content']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$result = curl_exec($ch) or die(curl_error($ch));

header("Location: index.php?olay=2");
}

?>

Additional information: My file has single-quotes at the end.

How can I solve this problem?

veriler.txt:

araba
ev
dükkan
mağaza

veriler.txt is in another server and I want to rewrite it with a textarea using post method

Answer 1

curl will encode for you if you pass an array, or you can use urlencode() in your existing code:

$content = array('bilgi' => $_POST['content']);
curl_setopt($ch, CURLOPT_POSTFIELDS, $content);

Answer 2

I think that you need to send the text as HTML using this functions nl2br(htmlentities()) :

 curl_setopt($ch, CURLOPT_POSTFIELDS, 'bilgi='.nl2br(htmlentities($_POST['content'])));

as

araba<br>
ev<br>

Then when you receive it extract the text from html code using str_replace( "<br>" , "\\n" , $_POST['bilgi']); , And write it into you file veriler.txt
