Preserve linebreak txt php

问题:

How can I read a .txt file from my server, and preserve it's linebreaks? Note that the linebreaks aren't like this /n or something, they are more like

this. You know, just a new line in plain text.

I would like to echo the .txt file from my server, this is in PHP or something, while preserving the linebreaks.

Thanks a heck in advance ! :)

For output? Just use nl2br

$file = file_get_contents( 'file.txt' );
echo nl2br( $file );

Also works with fopen.

The line breaks are preserved without you needing to do anything. You can easily verify this by running the code from the command line, for example with

php -r "readfile('text.txt');"

However, in HTML whitespace is collapsed by default. If you want to preserve it use the CSS white-space attribute like this:

<div style="white-space: pre"><?php readfile('text.txt'); ?></div>
