Volker's getOS() function needs to have the order of cases changed in the switch statement since "darwin" contains "win", which means that both "windows" and "darwin" will return self::OS_WIN. I've moved the 'dar' case above the 'win' case:

<?php
class System {

    const
OS_UNKNOWN = 1;
    const
OS_WIN = 2;
    const
OS_LINUX = 3;
    const
OS_OSX = 4;

   
/**
     * @return int
     */
   
static public function getOS() {
        switch (
true) {
            case
stristr(PHP_OS, 'DAR'): return self::OS_OSX;
            case
stristr(PHP_OS, 'WIN'): return self::OS_WIN;
            case
stristr(PHP_OS, 'LINUX'): return self::OS_LINUX;
            default : return
self::OS_UNKNOWN;
        }
    }

}
?>

PHP_EOL can be used like that:

<?php

$data
= 'some data'.PHP_EOL;
$fp = fopen('somefile', 'a');
fwrite($fp, $data);

?>

Which is the same of \r\n or \n depending on the OS.
You can put those lines in a while for example, and create a log file.

Don't use `PHP_EOL` for textarea of form to array, use it:

array_values(array_filter(explode("\n", str_replace("\r", '', $_POST['data']))))
