$data .='</html>\r\n';
file_put_contents( dirname(__FILE__) . '/new.php', $data);
?>
I tried \nor \r\n, they all can not make a new line:
我试过\nor \r\n，他们都不能换行：
1. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">\r\n<html xmlns="http://www.w3.org/1999/xhtml" lang="en">\r\n<head>\r\n</head>\r\n<body>\r\n<p>put something here</p>\r\n</body>\r\n</html>\r\n

Using \ror \nin single quotes carries it literally. use double quotes instead like "\r\n"
使用\r或\n在单引号中表示字面意思。使用双引号代替像 "\r\n"
So one line might become:
所以一行可能会变成：
$data .= "<head>\r\n";
or
或者
$data .='<head>' . "\r\n";

You are using single-quoted character literals, which don't interpret escape sequences.
Either switch to double-quoted strings or, preferably, use heredoc syntax.
您正在使用单引号字符文字，它不解释转义序列。
要么切换到双引号字符串，要么最好使用heredoc 语法。
<?php
$data = <<<CONTENTS
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org /TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">

<body>
<p>put something here</p>

</html>
CONTENTS;
file_put_contents( dirname(__FILE__) . '/new.php', $data);
?>
But really, why are you writing a hard-coded file? That's really strange.
但说真的，你为什么要写一个硬编码的文件？这真的很奇怪。
