How to split lines in a textarea using php

[cabbiepete]

In the thread http://www.thescripts.com/forum/thread11792.html this question was posed and while an answer was posted it wasn't explained at all why that worked. I thought I would post the answer in detail to help anyone else that searches for this. Read the original question and answer to get the context but I will cut to the reason.

The Reason the answer works and the other one doesn't

The \n is double quoted in the code that works. So 2 things were going wrong the doubled slash and the single quotes, I suspect that [e-mail] had tried single slash also (as I had).

So "\n" works to split on new lines where as '\n' doesn't.


The original question:

Hi.

I've got a textarea form and send a text via 'POST' to a PHP code:
-------------
data1
data2
data3
--------------

I use this piece of code:
-------------
$data = $_REQUEST["data"];
$data_array = split('\\n', $data);
------------

But it doesn't work. I tried also with '\n', '\r\n' and '\\r\\n'
without success.

Any suggestion? Regards.

The correct answer:

For some reason its working quite fine for me with this:

textarea.php:
-------------
<?php
$sent = $_REQUEST[sent];
if($sent == "yes") {
$data = $_REQUEST[data];
$data_array = split("\n", $data);
print_r($data_array);
} else {
echo "<form action='textarea.php' method='post'>";
echo "<textarea cols='10' rows='10' name='data'></textarea>";
echo "<input type='hidden' name='sent' value='yes'>";
echo "<input type='submit' value='Send'>";
echo "</form>";
}
?>
-------------

It produces this:

Array
(
[0] => data1
[1] => data2
[2] => data3
)

Is this a question...?
