What about using <code>$xml['VarNum']</code> ?

Like this :

<pre><code>$str = &lt;&lt;&lt;XML
&lt;VAR VarNum="90"&gt;
 &lt;option&gt;1&lt;/option&gt;
&lt;/VAR&gt;
XML;

$xml=simplexml_load_string($str);
$option=$xml-&gt;option;

var_dump((string)$xml['VarNum']);
</code></pre>

(I've used <code>simplexml_load_string</code> because I've pasted your XML into a string, instead of creating a file ; what you are doing with <code>simplexml_load_file</code> is fine, in your case !)

Will get you

<pre><code>string '90' (length=2)
</code></pre>

With simpleXML, you access attributes with an array syntax.
 And you have to cast to a string to get the value, and not and instance of <code>SimpleXMLElement</code>

For instance, see example #5 of <a href="http://php.net/manual/en/simplexml.examples-basic.php" rel="noreferrer">Basic usage</a> in the manual :-)

blocks|key|337027|text|您应该能够使用SimpleXMLElement::attributes()获得此结果|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|337028|试试这个：|337029|$xml=simplexml_load_file($file);
foreach($xml->Var[0]->attributes()+as+$a+=>+$b)+{
++++echo+$a,'="',$b,"\"\n";
}|code-block|syntax|javascript|337030|这将显示第一个foo元素的所有名称/值属性。它是一个关联数组，所以你也可以这样做：|style|CODE|337031|$attr+=+$xml->Var[0]->attributes();

You should be able to get this using <a href="http://ca.php.net/manual/en/function.simplexml-element-attributes.php" rel="noreferrer">SimpleXMLElement::attributes()</a>

Try this:

<pre><code>$xml=simplexml_load_file($file);
foreach($xml-&gt;Var[0]-&gt;attributes() as $a =&gt; $b) {
 echo $a,'="',$b,"\"\n";
}
</code></pre>

That will show you all the name/value attributes for the first <code>foo</code> element. It's an associative array, so you can do this as well:

<pre><code>$attr = $xml-&gt;Var[0]-&gt;attributes();
echo $attr['VarNum'];
</code></pre>

I applied the below code 

<pre><code>$xml = simplexml_load_string($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

Try this
<pre><code>$xml-&gt;attributes()['YourPropertyName']; //check property case also
</code></pre>

Sorry if this seems like an easy question, but I've started pulling hair out on this...

I have a XML file which looks like this...

<pre><code>&lt;VAR VarNum="90"&gt;
 &lt;option&gt;1&lt;/option&gt;
&lt;/VAR&gt;
</code></pre>

I'm trying to get the VarNum. 

So far I've been successful using the follow code to get the other information:

<pre><code>$xml=simplexml_load_file($file);
$option=$xml-&gt;option;
</code></pre>

I just can't get VarNum (the attribute value I think?)

Thanks!

How to get the value of an attribute from XML file in PHP?

抱歉，如果这看起来是一个简单的问题，但我已经开始在这个问题上拔毛了.我有一个XML文件，看起来像这样...<VAR VarNum="90"> <option>1</option></VAR>我正在尝试获取VarNum。到目前为止，我已经成功地使用以下代码获取了其他信息：$xml=simplexml_load_file...
