You need to use double quotes:
您需要使用双引号：
echo($string."\r");
^ ^
single quoted strings do not honor ANY metacharacters, except the backslash itself.
单引号字符串不支持任何元字符，除了反斜杠本身。

The accepted answer not work for me.
my try is "\r\n"
接受的答案对我不起作用。我的尝试是"\r\n"
echo 'This is some text before newline';
echo "\r\n"."text in new line";
//OR
echo 'This is some text before newline'."\r\n"."text in new line";
cmd output will be:
cmd 输出将是：
This is some text before newline
这是换行前的一些文字
text in new line
新行中的文本
