PHP Text area foreach line

Question

Im trying to code a php script that will loop a process for each line in a Textarea post. I was wondering if someone can post an example.

Answer 1

foreach(explode("\n", $text) as $line) {
    // do something
}

See http://uk2.php.net/manual/en/function.explode.php

Answer 2

You might have to use \r\n instead of just \n for textarea (I remember figuring it out for quite a while)
