php - 警告 : get_class() expects parameter 1 to be object

Question

一周前我写了一个代码，它运行良好。但是今天当我检查它时，它给了我一些问题，比如

Warning: get_class() expects parameter 1 to be object, array given in /home/ccc/public_html/horoscope/xml2json.php on line 182

Warning: get_class() expects parameter 1 to be object, string given in /home/ccc/public_html/horoscope/xml2json.php on line 182

Warning: get_class() expects parameter 1 to be object, string given in /home/ccc/public_html/horoscope/xml2json.php on line 182

Warning: get_class() expects parameter 1 to be object, string given in /home/ccc/public_html/horoscope/xml2json.php on line 182

Warning: get_class() expects parameter 1 to be object, string given in /home/ccc/public_html/horoscope/xml2json.php on line 182

我的部分代码是

$currentDate = date("n/j/Y"); 
 echo($hdate);
require_once("xml2json.php");

$testXmlFile = "http://www.findyourfate.com/rss/horoscope-astrology-feed.asp?mode=view&todate=$currentDate";
echo($testXmlFile);
$xmlStringContents = file_get_contents($testXmlFile); 
$jsonContents = "";
$jsonContents = xml2json::transformXmlStringToJson($xmlStringContents);
$obj =json_decode($jsonContents);
$rows = array();
foreach($obj->rss->channel->item as $item) 

xml2json中的182行是

if (get_class($simpleXmlElementObject) == SIMPLE_XML_ELEMENT_PHP_CLASS) {
    // Get a copy of the simpleXmlElementObject
    $copyOfsimpleXmlElementObject = $simpleXmlElementObject;
    // Get the object variables in the SimpleXmlElement object for us to iterate.
    $simpleXmlElementObject = get_object_vars($simpleXmlElementObject);
}       

这里是 simpleXMLElement 对象的 var_dump 的 pastebin 链接

谁能帮我解决突然发生的问题，它不起作用。

谢谢

只需添加 is_object 检查

if (is_object($simpleXmlElementObject) && get_class($simpleXmlElementObject) == SIMPLE_XML_ELEMENT_PHP_CLASS) {
