+ * Arguments : $contents - The XML text
+ * $namespaces - true or false include namespace information in the returned array as array elements.
+ * $get_attributes - 1 or 0. If this is 1 the function will 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 will change the way the resulting array sturcture. For 'tag', the tags are 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', true, 1, 'attribute'));
