php-dev, [PHP-DEV] PHP 5.3 bug or changed feature?? Hello Everyon,

Casting a SimpleXML object to an array gives different results in PHP
5.2.5 and PHP 5.3-dev.

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"]=>
string(12) "SEAT CONTROL"
}
["module"]=>
array(2) {
[0]=>
string(2) "pp"
[1]=>
string(2) "sc"
}
}
array(2) {
["@attributes"]=>
array(1) {
["name"]=>
string(12) "SEAT CONTROL"
}
["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) {
[0]=>
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) {
["name"]=>
string(12) "SEAT CONTROL"
}
["module"]=>
array(2) {
[0]=>
string(2) "pp"
[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?

Hi Frank,

please open a bugreport about this issue. This would start the internal
process of verifying this.

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?

This happens with many more functions. So i can verify this bug.

php -r "echo md5(serialize(simplexml_load_file('example.xml'))) . PHP_EOL .
phpversion() . PHP_EOL;"

Output PHP 5.2.5:
a6d7776fcb0e9c085b0d5972df792dac
5.2.5

Output PHP 5.3.0-dev (latest snap)
3e442cb7c8507c8941011735bb46e6de
5.3.0-dev

this is intended. The 5.2 solution is just a hack and returns a wrong
result in the first place. The hack was however introduced to make
development easier. Now with 5.3 we were able to change the API and coudl
apply the solution that was first developed in HEAD.

Will there be another way to do this or will they only be accessible from
the object?
