Hi Frank, Frank M. Kromann wrote:

Hello Everyon, Casting a SimpleXML object to an array gives different results in PHP 5.2.5 and PHP 5.3-dev. This is due to the implementation of the get_debug_info handler merged from HEAD.

The same result happens when calling get_object_vars on a SimpleXMLElement object. Marcus, was it intended to only include @attributes with print_r/var_dump? Rob

Source: $xml = simplexml_load_file("sample.xml"); foreach($xml->column as $column) {
    var_dump($column);
    var_dump((array)$column);
} sample.xml ?xml version="1.0"?> <cpdata>
    <column name="ENTERTAINMENT">
        <module>cv</module>
        <module>entsimp</module>
    </column>
    <column name="SEAT CONTROL">
        <module>pp</module>
        <module>sc</module>
    </column>
</cpdata> PHP 5.2 output: object(SimpleXMLElement)#4 (2) { ["@attributes"]=> array(1) {
    ["name"]=>
    string(13) "ENTERTAINMENT"
} ["module"]=> array(2) {
    [0]=>
    string(2) "cv"
    [1]=>
    string(7) "entsimp"
} } array(2) { ["@attributes"]=> array(1) {
    ["name"]=>
    string(13) "ENTERTAINMENT"
} ["module"]=> array(2) {
    [0]=>
    string(2) "cv"
    [1]=>
    string(7) "entsimp"
} } object(SimpleXMLElement)#5 (2) { ["@attributes"]=> array(1) {
    ["name"]=>

    [1]=>

} ["module"]=> array(2) {
    [0]=>
    string(2) "pp"
    [1]=>
    string(2) "sc"
} } PHP 5.3 output: object(SimpleXMLElement)#4 (2) { ["@attributes"]=> array(1) {
    ["name"]=>
    string(13) "ENTERTAINMENT"
} ["module"]=> array(2) {

    string(2) "cv"
    [1]=>
    string(7) "entsimp"
} } array(1) { ["module"]=> array(2) {
    [0]=>
    string(2) "cv"
    [1]=>
    string(7) "entsimp"
} } object(SimpleXMLElement)#5 (2) { ["@attributes"]=> array(1) {

    [1]=>
    string(2) "sc"
} } array(1) { ["module"]=> array(2) {
    [0]=>
    string(2) "pp"
    [1]=>
    string(2) "sc"
} } Not that the attributes are gone when SimpleXML objects are converted in PHP 5.3. Is this a bug or a feature change? - Frank
