                        (
                            [DomainName] => domain1.com
                            [DomainNameID] => 153033597

                        )

                )

            [domaincount] => 2

    [debug] => SimpleXMLElement Object
        (
        )

上面的输出是使用 PHP 中的 print_r 函数显示的

如何在 PHP 中使用 foreach 循环遍历 DomainDetail 的数组

我尝试使用print_r($xml->DomainDetail); 和print_r($xml["DomainDetail"]);

但使用此print_r 没有显示任何内容

Answer 1

foreach($xml->GetAllDomains->DomainDetail as $domainDetail) {
    echo $domainDetail->DomainName, "\n";
    echo $domainDetail->DomainNameID, "\n";
    echo $domainDetail->{'expiration-date'}, "\n";
    // etc..
}
