Answer 1

function stripEmptyTags ($result)
{
    $regexps = array (
    '~<(\w+)\b[^\>]*>\s*~',
    '~<\w+\s*/>~'
    );

    do
    {
        $string = $result;
        $result = preg_replace ($regexps, '', $string);
    }
    while ($result != $string);

    return $result;
}


$string = "text 
  
";
echo stripEmptyTags ($string);
