function parameter is ignored when set to false

[Parivalavan]

Thanks for the script.

I added a functionality to do a compare case insensitive by adding an additional parameter 'ignore_case'.

    $phpStringCompare = new StringCompare($string1, $string2,
                                    array('remove_html_tags'=>true, 'remove_extra_spaces'=>true, 'ignore_case'=>true,
                                    'remove_punctuation'=>true, 'punctuation_symbols'=>Array('.', ','))
                                );

I found that when I set the 'ignore_case' parameter to true the script functions as normal. When I set the 'ignore_case' to false then too the script does a case insensitive comparison. By modifying the lines from

        if (!empty($params['ignore_case'])) {
            $this->_ignore_case = $params['ignore_case'];
        }

to

        if (isset($params['ignore_case'])) {
            $this->_ignore_case = $params['ignore_case'];
        }

the script works as expected. This I guess is because of !empty check. false value returns empty using the check and hence skips the steps. Please correct me if I'm missing something. Thanks, Pari
