PHP: XML to Array and backwards

2007-02-06T23:29:00.000-08:00

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
                       )
               )
       )
)

Example #2: (1.xml as described before)


$xml=xml2ary(file_get_contents('1.xml'));
$xml['ddd']['_c']['twomore']=$xml['ddd']['_c']['onemore'];
$xml['ddd']['_c']['twomore']['_c']['tt'][0]['_v']='hello';
echo ary2xml($xml);

Will output result:


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