XMLToArray Generator Class

Here is a PHP class that read xml file and make an array. First save this class file as xmltoarray.php and then create an object like new XmlToArray($xml_data). Finally just call createArray() function. It will be helpful when we don’t want to use database or any kind of web services. Bellow i have given full source code. I think it will be helpful.
