Cleaning textarea contents

I created this to remove duplicates and trim each line of a textarea box. And it works.

I am wondering if there is a more efficient way to write this and possibley make it into a function.

// TRIM, CREATE ARRAY, REMOVE DUPLICATES, MAKE STRING, TRIM AGAIN
$array = array_unique(explode("\r\n", trim($field1)));
$cleaned = implode("\r\n", $array);
$trimmed = preg_replace ( "/\s\s+/" , "\r\n" , $cleaned );
echo $trimmed;

It looks pretty good to me.  I guess you could turn it into a function by doing...

function cleanText($field)
{
   $array = array_unique(explode("\r\n", trim($field)));
   $cleaned = implode("\r\n", $array);
   $trimmed = preg_replace ( "/\s\s+/" , "\r\n" , $cleaned );
   return $trimmed;
}

Then you would just run...

$trimmed_variable = cleanText($_POST['textbox']);

Then your $trimmed_variable would be the new text.

Thanks for confirming this, I implemented this as a function and it helped reduce my 27 lines of code down to 9 lines.
