Is a new line = \n OR \r\n?

Question

I\'ve seen many developers use different methods to split a string by new lines, but i\'m confused which is the correct: \\r\\n OR \\n only?

Answer 1

If you are programming in PHP, it is useful to split lines by \n and then trim() each line (provided you don't care about whitespace) to give you a "clean" line regardless.

foreach($line in explode("\n", $data))
{
    $line = trim($line);
    ...
}
