Return Selected checkbox values

public Hashtable returnGridSelectedIds(GridView gv1, string chkBoxField)
{
    string Id = "";
    Hashtable ht = new Hashtable();
    if (gv1.Rows.Count > 0)
    {
        foreach (GridViewRow gvr in gv1.Rows)
        {
            HtmlInputCheckBox htmChkBox = (HtmlInputCheckBox)gvr.FindControl(chkBoxField);
            if (htmChkBox.Checked)
                Id += htmChkBox.Value + ",";
        }
    }
 
    if (Id.ToString() != "")
        Id = Id.Substring(0, Id.Length - 1);
      ht["Ids"] = Id;
    return ht;

Truncate a string without breaking a word

function truncate_str($string, $length = 80, $etc = '...',$break_words = false)
{
    if ($length == 0)
        return '';
 
    if (strlen($string) > $length) {
        $length -= strlen($etc);
        if (!$break_words)
            $string = preg_replace('/\s+?(\S+)?$/', '', substr($string, 0, $length+1));
 
        return substr($string, 0, $length).$etc;
    } else
        return $string;
