我试图将一个对象转换为字符串并比较它们,但它不工作。比较XML对象和字符串
任何人都可以看到问题吗?
Hello <?php $country = (string)$_POST["country"]; echo $country; ?><br>
<?
//echo gettype($country), "\n";
$xml=simplexml_load_file("info.xml");
foreach($xml->children() as $xml_country){
//echo $xml_country->id . ": " . "<br>";
//$id = array((string) $xml_country->id);
$id = strip_tags($xml_country->id->asXML());
echo $id;
echo "id: ", gettype($id), "\n";
echo "country: ", gettype($country), "\n";
echo "\n";
if($country == $id){
echo $xml_country->id . ": " . "<br>";
}
}
?>
Info.xml

什么是你的脚本输出目前,又是什么内容info.xml是什么样子? –
@BrianDriscoll请参阅编辑。 –
好的,你期望的输出是什么?你应该知道'=='做了一个松散的类型比较,所以你不需要使用该运算符来比较两个字符串。 –
