Try <code>"\n\r"</code> (double quotes) or just <code>"\n"</code>.

If you're not sure which type of EOL you have, run a str_replace before your explode, replacing "\n\r" with "\n".

Place the <code>\n</code> in double quotes:

<code>explode("\n", $_POST['skuList']);</code>

In single quotes, if I'm not mistaken, this is treated as <code>\</code> and <code>n</code> separately.

It doesn't matter what your system uses as newlines if the content might be generated outside of the system.
I am amazed after receiving all of these answers, that no one has simply advised the use of the <code>\R</code> escape sequence. There is only one way that I would ever consider implementing this in one of my own projects. <code>\R</code> provides the most succinct and direct approach.

For a new line and carriage return (as in Windows files), it's as you posted. Is your skuList a text area?

First of all, I think it's usually <code>\r\n</code>, second of all, those are not the same on all systems. That will only work on windows. It's kind-of annoying trying to figure out how to replace new lines because different systems treat them differently (see <a href="http://en.wikipedia.org/wiki/Newline" rel="nofollow">here</a>). You might have better luck with just <code>\n</code>.

Losing line breaks from posting from input textboxes? 
What works faster for me is to copy paste any text or Excel or HTML table type or newline type of data and paste it into a textarea instead of an inputextbox:
this keeps the linebreaks intact in the POST.

<pre><code> &lt;textarea id="txtArea" name="txtArea" rows="40" cols="170"&gt;&lt;/textarea&gt;
 &lt;br&gt;
 &lt;input type="submit" value="split lines into array" /&gt; 
</code></pre>

in the form receiving file: 

<pre><code> $txtArea =''; 
 $txtArea = $_POST['txtArea']; 
 $TA = $_POST['txtArea']; 
 $string = $TA; 
 $array = preg_split ('/$\R?^/m', $string); 
// or any of these: 
// $array = explode(PHP_EOL,$string); 
// $array = explode("\n", $txtArea); 
 echo "&lt;br&gt;A0: ".$array[0];
 echo "&lt;br&gt;A1: ".@$array[1];
 echo "&lt;br&gt;A2: ".@$array[2];
</code></pre>

Here is what worked for me. Tested in PHP 5.6 as well as as PHP 7.0:

<pre><code> $skuList = str_replace("\\r\\n", "\n", $_POST['skuList']);
 $skuList = str_replace("\\n\\r", "\n", $skuList);

This method always works for me:

<pre><code>$uniquepattern="@#$;?:~#abcz"//Any set of characters which you dont expect to be present in user input $_POST['skuList'] better use atleast 32 charecters.
$skuList=explode($uniquepattern,str_replace("\r","",str_replace("\n",$uniquepattern,$_POST['skuList'])));
</code></pre>

Simple, right? Well, this isn't working :-\

<pre><code>$skuList = explode('\n\r', $_POST['skuList']);
</code></pre>

Explode PHP string by new line

很简单，对吧？好吧，这不起作用:-\$skuList = explode('\n\r', $_POST['skuList']);
