PHP function Description and examples

/**

* Xml2array () would convert the given XML text to a array in the XML structure.
* link:http://www.bin-co.com/php/scripts/xml2array/
* Arguments: $contents-the XML text
* $get _attributes-1 or 0. If This is 1 the function would get the attributes as well as the tag values-this results in a different array structure In the return value.
* $priority-can be ' tag ' or ' attribute '. This would change the resulting array sturcture. For ' tag ', the tags is given more importance.
* Return:the parsed XML in an array form. Use Print_r () to see the resulting array structure.
* Examples: $array = Xml2array (file_get_contents (' feed.xml '));
* $array = Xml2array (file_get_contents (' Feed.xml ', 1, ' attribute '));
