xml 2 array and array to xml

I’ve tried this function with google feed but doesn’t seem to work. I haven’t look into details of it yet anyways you can try it and give it a shot. You can also use this for array to xml. Just check the link of the original post for more info.

PHP: XML to Array and backwards

Here the XML with PHP solution: XML->Array and Array->XML.
Work with it as with usual array.

Format XML->Array
_c - children
_v - value
_a - attributes

This is 1.1

Example #1 (1.xml):

<ddd>
<onemore dd="55">
<tt>333</tt>
<tt ss="s1">555</tt>
<tt>777</tt>
</onemore>
<two>sdf rr</two>
</ddd>

The code:

$xml=xml2ary(file_get_contents('1.xml'));
print_r($xml);

Here is the Array result:

Array
(
[ddd] => Array (
[_c] => Array (
[onemore] => Array (
[_a] => Array (
[dd] => 55
)
[_c] => Array (
[tt] => Array (
[0] => Array (
[_v] => 333
)
[1] => Array (
[_a] => Array (
[ss] => s1
)
[_v] => 555
)
[2] => Array (
[_v] => 777
)
)
)
)
[two] => Array (
[_v] => sdf rr
)
)
)
)
