mysql + new row

[seby]

i have a string with outputs a bunch of IPs each on a new line, example:

12.232.2.232
12.232.2.232
12.232.2.232
12.232.2.232

is it possible to insert each IP into its own row? how can i do this if they are all in one string?

[jtacon]

$str="12.232.2.232
12.232.2.232
12.232.2.232
12.232.2.232";

$arr=explode("\n",$str);

foreach($arr as $ip) {
  // here $ip contains each IP in the string $str
}
