Getting "PHP Parse error: syntax error, unexpected 'echo' (T_ECHO)"

I'm a beginner in PHP. I'm trying to write an XML, but continuously getting the error. I know I may have forgotten a semicolon, but can't find exactly where. Thanks in advance. Here is my code sample:

 $dirName = "../data/";
    if(!file_exists($dirName){
        echo "Directory not found";
    }
    else {
        if (! is_writable($dirName)) {
            echo "No write permission";
        } else {
            $xmlDoc->save($dirName . 'generated-xml.xml');
        }
    }
