Introduction:
I was having a problem trying to split a string of multiple lines from an online form using the flowing code:
<?php $arry_names = split("\n", $names); ?>
This was producing an unexpected line break. I searched the web to see if anyone had the same problem and found that I needed to check for “returns” (\r) also. So now when I’m splitting data by lines, I use the following code:
<?php $arry_names = split("[\n|\r]", $names); ?>
I think it's enough using split("[\n]",$names);
split (“[\r\n|\n]“, $array); is the solution!
what about
split(‘[\r\n|\r|\n]‘,$array)
?
Anyway, thanks for your help! I really appreciate.
Sorry,
php says:
This function [split] has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.
Use preg_split instead.

Also, your regexp is total BS. You’re confusing (\r|\n) with [\r\n]. [] doesn’t need |, since it’s for single characters. The 100% sure-fire cross-platform separator is (?:\r\n|\r|\n), which can be abbreviated to (?:\r\n?|\n).
When splitting an empty string you don’t get an empty array, instead you get an array with an empty string as it’s only element. To improve Tim’s answer here is a function:
function split_lines ($string) {
$lines = preg_split(“/\r\n|\r|\n/”, $string);
if (count($lines) == 1 && !$lines[0]) {
return array();
}
return $lines;
}
