Not exploding by PHP_EOL

[jtwebb]

Here is an example of my .env file:

DB_NAME=example
DB_USER=root
DB_PASSWORD=
DB_HOST=

WP_ENV=development
WP_HOME=http://example.com
WP_SITEURL=http://example.com/wp

For some reason line 21 in Dotenv.php, $lines = explode(PHP_EOL, $fc);, doesn't explode the variables. If I replace PHP_EOL with "\n" it works just fine. Any ideas as to why this would be the case?

I'm not sure. PHP_EOL should be your system's end of line character. I just did some research though and it seems like "\r\n" is best for wide compatability. Can you verify that explode("\r\n", ... ) works on your system?

"\r\n" doesn't work. It still doesn't break each line into a value. It just throws everything into $lines[0] (same as PHP_EOL). It's odd that it doesn't work since I have the same setup on a different local virtual server and deployment server and they both work fine. There's nothing different about this setup, yet it still won't work without using "\n".

I've the same problem. I'm using IIS to simulate PHP and to parse the Dotenv class.
Apparently the PHP_EOL doesn't contain any line-break information, but explode("\n", ... ); does work on my system.

Update:
At a closer look, I think the PHP_EOL does contain a "\r\n", however, it of course doesn't fix the problem because only the "\n" here.

And I found a similar topic about this: avalanche123/doxphp#7

I don't think you should rely on PHP_EOL.

I would recommend using something like this: http://stackoverflow.com/questions/11066857/detect-eol-type-using-php

It seems like PHP_EOL is a good practice when creating new lines dynamically, not when exploding.

Perhaps you can use the first answer:
$lines = array_map("rtrim", explode("\n", $fc));
Or something similar since it will break on old macs. Perhaps something like this, I've tested this and it works fine at my system:
$lines = preg_split('/\r\n|\r|\n/', $fc);

This worked for me

ini_set("auto_detect_line_endings", true);
$lines = file($filePath);

It uses PHP's auto line detection (see: L852), which appears to be more or less the same as the last line of @harm-less's post.

I'd recommend going with his method on the off chance a user might not be happy with changing an ini setting (although you could use ini_get() and then change it back afterwards, but whatever; doesn't seem like that's necessary).

This has been fixed.
