Additional you can use the system-dependent constant PHP_EOL

Escape sequences are only parsed when inside double quotes, not single quotes.
转义序列仅在双引号内时才被解析,而不是单引号内。

Better notto concatenate anything in PHP, because it may lead to unexpected results, instead use a comma:
最好不要在 PHP 中连接任何东西,因为它可能会导致意想不到的结果,而是使用逗号:
echo 'Text with new line' , PHP_EOL;
This will be faster too by the way: not concatenating and avoiding parsed double quotes.
顺便说一下,这也会更快:不连接并避免解析双引号。
