如何在file_put_contents中添加<br>？

A simple question, But I could not find a solution

$file = 'file.txt';
file_put_contents($file, "$time|$data<br>", FILE_APPEND);

file right now, after 2 times in loop:

03-24-2018|test03-24-2018|test

I need:

03-24-2018|test
03-24-2018|test

<?php
$file = 'file.txt';

file_put_contents($file, "$time|$data
", FILE_APPEND);

?>

You can use the predefined PHP_EOL constant, new line characters are different depends on operating systems:

Windows:

Mac OS:

Unix-like systems:

$content = "$time|$data" . PHP_EOL;
