Cut string and rest of the string ????

I am using a cut string function like

function cut_string($string_to_cut, $number_words, $append="Read more"){
	$string = explode(" ", $string_to_cut);
	if(count($string) < $number_words){
		for($x=0; $x < $number_words; $x++)
		{
			$string_return .= $string[$x] . " ";
		}
		$return_string = substr($string_return, 0, -1);
	} else {
	for($x=0; $x < $number_words; $x++)
		{
			$string_return .= $string[$x] . " ";
		}
		$string = substr($string_return, 0, -1);
			$return_string = $string.' <a href="#">'.$append.'</a>';
	}
	return($return_string);
}

Code (markup):

$intro = cut_string($text, 30);

But now I need the rest of the string, so from 30 until the end???How can I get the rest in a variable???

tx nikolas for pointing me in the right direction. But I am stuck

I have added this to my function

$data['intro'] = $return_string;
$data['rest'] = substr($string_to_cut, $number_words);

function cut_string($string_to_cut, $number_words, $append="Read more")
{
	$string = explode(" ", $string_to_cut);
	if(count($string) < $number_words){
		for($x=0; $x < $number_words; $x++)
		{
			$string_return .= $string[$x] . " ";
		}
		$return_string = substr($string_return, 0, -1);
	} else {
	for($x=0; $x < $number_words; $x++)
		{
			$string_return .= $string[$x] . " ";
		}
		$string = substr($string_return, 0, -1);
			$return_string = $string.' <a href="#" >'.$append.'</a>';
	}
	$data['intro'] = $return_string;
	$data['rest'] = substr($string_to_cut, $number_words);
	return $data;
}

Code (markup):

But that didn't work as I aspected, where do I go wrong???

 

As I am in a little rush, I wont read your code.

What do you want this to do? Give a memo and get the first n words from it?

 

Can you post what is going wrong? e.g. the output of tht function using a sample string.

 

function cut_string($string_to_cut, $number_words, $append="Read more")
{
    $string = explode(" ", $string_to_cut);
    if(count($string) < $number_words){
        for($x=0; $x < $number_words; $x++)
        {
            $string_return .= $string[$x] . " ";
        }
        $return_string = substr($string_return, 0, -1);
    } else {
    for($x=0; $x < $number_words; $x++)
        {
            $string_return .= $string[$x] . " ";
        }
        $string = substr($string_return, 0, -1);
            $return_string = $string.' <a href="#" >'.$append.'</a>';
    }
    $data['intro'] = $return_string;
    $data['rest'] = substr($string_to_cut, $number_words);
    return $data;
}

$test = 'The use of cookies on this forum is optional, but may enhance your experience of the site.';

$intro =  cut_string($test, 3);

echo "Introduction: <strong>".$intro['intro']."</strong><br/><br/>";
echo "Rest: ".$intro['rest'];
?>

Code (markup):

Intro shows "The use of" as expected and I thought the output for Rest:
