Question

Say I have a text area, user enters information exactly like styled below:

Ice cream
Chocolate

then submits this information, I want to retrieve the information EXACTLY like so:

Ice cream, Chocolate

Is this the best way to do it:

$arr = explode("\n", $var);
$arr = implode(",", $arr);

When doing it like this, it puts the information out like so:

Ice cream , Chocolate

Note the space after cream, will a simple trim() fix this?

Answer 1

$text = preg_replace("~\s*[\r\n]+~", ', ', $text);
