How to Retrieve Attribute Values from XML in PHP?

Getting Attribute Values from XML in PHP

Retrieving attribute values from an XML file can be a straightforward task in PHP using the SimpleXMLElement class.

Suppose you have an XML file that resembles this:

<VAR VarNum="90">
  <option>1</option>
</VAR>

To obtain the value of the VarNum attribute, you can leverage the attributes() method of the SimpleXMLElement object.

$xml = simplexml_load_file($file);
foreach ($xml->Var[0]->attributes() as $attributeName => $attributeValue) {
    echo "$attributeName=\"$attributeValue\"\n";
}

This code iterates through all the attributes of the first Var element and prints their names and values in a structured format.

Alternatively, you can directly access the attribute value by name:

$attr = $xml->Var[0]->attributes();
echo $attr['VarNum'];
