[英]How to get the value of an attribute from XML file in PHP?
Sorry if this seems like an easy question, but I've started pulling hair out on this...对不起,如果这似乎是一个简单的问题,但我已经开始在这个问题上拉头发了......
I have a XML file which looks like this...我有一个看起来像这样的 XML 文件...
<VAR VarNum="90">
<option>1</option>
</VAR>
I'm trying to get the VarNum .我正在尝试获取VarNum 。
So far I've been successful using the follow code to get the other information:到目前为止,我已成功使用以下代码获取其他信息:
$xml=simplexml_load_file($file);
$option=$xml->option;
I just can't get VarNum (the attribute value I think?)我只是无法获得 VarNum(我认为的属性值?)
Thanks!谢谢!
You should be able to get this using SimpleXMLElement::attributes()你应该能够使用SimpleXMLElement::attributes()
Try this:尝试这个:
$xml=simplexml_load_file($file);
foreach($xml->Var[0]->attributes() as $a => $b) {
echo $a,'="',$b,"\"\n";
}
That will show you all the name/value attributes for the first foo
element.这将显示第一个
foo
元素的所有名称/值属性。 It's an associative array, so you can do this as well:这是一个关联数组,因此您也可以这样做:
$attr = $xml->Var[0]->attributes();
echo $attr['VarNum'];
What about using $xml['VarNum']
?使用
$xml['VarNum']
怎么样?
Like this :像这样 :
$str = <<<XML
<VAR VarNum="90">
<option>1</option>
</VAR>
XML;
$xml=simplexml_load_string($str);
$option=$xml->option;
var_dump((string)$xml['VarNum']);
(I've used simplexml_load_string
because I've pasted your XML into a string, instead of creating a file ; what you are doing with simplexml_load_file
is fine, in your case !) (我使用
simplexml_load_string
是因为我已将您的 XML 粘贴到一个字符串中,而不是创建一个文件;您对simplexml_load_file
所做的一切都很好,就您而言!)
Will get you会得到你
string '90' (length=2)
With simpleXML, you access attributes with an array syntax.使用 simpleXML,您可以使用数组语法访问属性。
And you have to cast to a string to get the value, and not and instance of SimpleXMLElement
并且您必须转换为字符串才能获取值,而不是
SimpleXMLElement
实例
For instance, see example #5 of Basic usage in the manual :-)例如,请参阅手册中基本用法的示例 #5 :-)

I applied the below code我应用了下面的代码
$xml = simplexml_load_string($response);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
print_r($array);
but it is not use full i want all the data in single array in php但它没有完全使用我想要php中单个数组中的所有数据
尝试这个
$xml->attributes()['YourPropertyName']; //check property case also
