php explode new lines content from a txt file

Question

I have txt file with email addresses under under the other like :

[email protected]
[email protected]

So far I managed to open it with

 $result = file_get_contents("tmp/emails.txt");

but I don't know to to get the email addresses in an array. Basically I could use explode but how do I delimit the new line ? thanks in advance for any answer !

Answer 1

$lines = preg_split('/\r\n|\n|\r/', trim(file_get_contents('file.txt')));
