Extract text from MEDIUM TEXT

It seems a strange thing to do but who am i to judge

Code:

function get_str_by_middle_word($str,$word,$word_limit = 10)
{
    $words = str_word_count($str);
    if(($key = array_search($word,$words) === FALSE)
    {
        return '';
    }

    $start = ($key < $word_limit)?0:$key-$word_limit;
    
    if($key+$word_limit > count($words)-1)
    {
        return implode(' ',array_slice($words,$start));
    }
    else
    {
        return implode(' ',array_slice($words,$start,$key+$word_limit));
    }
}

The code is untested.
