Make an excerpt with php without cutt last word

Hy! I'm trying to make an excerpt for long titles but last word should not be cutted. I've read an related topic of this question but it seems it refer to another problem (on search result). here's my function now 

function excerpt($title) {
        $new = substr($title, 0, 27);

        if (strlen($title) > 30) {
            return $new.'...';
        } else {
            return $title;
        }
    }

I have modified @mohd zubair khan's solution to meet the requirements of the question.

the question was about shortening of string without cutting it from tails. So here is my code.

function strWordCut($string,$length)
{
    $str_len = strlen($string);
    $string = strip_tags($string);

    if ($str_len > $length) {

        // truncate string
        $stringCut = substr($string, 0, $length-15);
        $string = $stringCut.'.....'.substr($string, $str_len-10, $str_len-1);
    }
    return $string;
}

function strWordCut($string,$length,$end='....')
{
    $string = strip_tags($string);

    if (strlen($string) > $length) {

        // truncate string
        $stringCut = substr($string, 0, $length);

        // make sure it ends in a word so assassinate doesn't become ass...
        $string = substr($stringCut, 0, strrpos($stringCut, ' ')).$end;
    }
    return $string;
}

I was actually able to solve it with: 

if (strlen($title) < 30) {
     return $title;
} else {

   $new = wordwrap($title, 28);
   $new = explode("\n", $new);

   $new = $new[0] . '...';

   return $new;
}

Here is a function that does what you want, and a test function to check it is working as expected.

function excerpt($title, $cutOffLength) {

    $charAtPosition = "";
    $titleLength = strlen($title);

    do {
        $cutOffLength++;
        $charAtPosition = substr($title, $cutOffLength, 1);
    } while ($cutOffLength < $titleLength && $charAtPosition != " ");

    return substr($title, 0, $cutOffLength) . '...';

}

function test_excerpt($length) {

    echo excerpt("This is a very long sentence that i would like to be shortened", $length);
    echo "
";
    echo excerpt("The quick brown fox jumps over the lazy dog", $length);
    echo "
";
    echo excerpt("nospace", $length);
    echo "
";
    echo excerpt("A short", $length);
    echo "

";

}

test_excerpt(5);
test_excerpt(10);
test_excerpt(15);
test_excerpt(20);
test_excerpt(50);

Outputs -

This is...
The quick...
nospace...
A short...

This is a very...
The quick brown...
nospace...
A short...

This is a very long...
The quick brown fox...
nospace...
A short...

This is a very long sentence...
The quick brown fox jumps...
nospace...
A short...

This is a very long sentence that i would like to be...
The quick brown fox jumps over the lazy dog...
nospace...
A short...
