如何访问PHP中以@开头的stdClass成员

I have some json object that I decoded, and one of the attributes starts with an "@" and I can't access the element with php because it throws an error.

                    [offers] => stdClass Object
                    (
                        [@attributes] => stdClass Object
                            (
                                [id] => levaka0B8a
                            )
                    )

How would I go about accessing attributes?

You can access it by a string:

echo $obj->{'@attributes'}->id; // levaka0B8a

Or a variable:

$name = '@attributes';
echo $obj->$name->id;

For more information on how variables are defined and used, see the following docs:

• Variable Basics - Useful for learning what can be accessed as a variable without needing to use strings.
• Variable Variables - How we used the variable to act as the name for another variable. This can be dangerous so tread carefully

You could do this:

$object->{'@attributes'}

direct access is below from ircmaxwell or Richard Tuin, however you can decode JSON with second param true and recive array insted what could be an easier to access

Try to use,

$objSimpleXml->attributes()->id

Sample Code to Refer

<?php
$string = <<<XML
<a>
 <foo name="one" game="lonely">1</foo>
</a>
XML;

$xml = simplexml_load_string($string);
var_dump( $xml );
foreach($xml->foo[0]->attributes() as $a => $b) {
    echo $a,'="',$b,"\"
";
}
?>
