PHP XML goto Array function _php Tutorial

/*** 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 _attribu Tes-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 ')); * $array = Xml2array (file_get_contents (' Feed.xml ', 1, ' attribute '));     */function Xml2array ($contents, $get _attributes=1, $priority = ' tag ') {if (! $contents) return array ();         if (!function_exists (' xml_parser_create ')) {//print "' xml_parser_create () ' function not found!
