这个方法对我来说总是有效的:

$uniquepattern="@#$;?:~#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'])));

涵盖所有情况。不要依赖于您的输入来自Windows环境。

$skuList = preg_split("/\\r\\n|\\r|\\n/", $_POST['skuList']);

or

$skuList = preg_split('/\r\n|\r|\n/', $_POST['skuList']);

PHP_EOL表面上用于以跨平台兼容的方式查找换行符，因此它可以处理DOS/Unix问题。

试试这个:

$myString = "Prepare yourself to be caught
You in the hood gettin' shot
We going throw hell of blows
got my whole frame froze";

$myArray = explode(PHP_EOL, $myString);

print_r($myArray);

你试过用双引号吗?

这个方法对我来说总是有效的:

$uniquepattern="@#$;?:~#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'])));

虽然不完美，但我认为这是最安全的。添加nl2br:

$skuList = explode('<br />', nl2br($_POST['skuList']));
