How to Access XML Attribute Values Using PHP\'s SimpleXMLElement?

Accessing Attribute Values from an XML File in PHP

When working with XML files in PHP, retrieving attribute values can be a common task. Let's consider the example XML:

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

Getting Attribute Values with SimpleXMLElement

To get the "VarNum" attribute value, we can utilize the SimpleXMLElement::attributes() method. Here's how:

$xml = simplexml_load_file($file);
$attr = $xml->Var->attributes();
echo $attr['VarNum']; // Output: 90

Looping through All Attributes

If you need to process multiple attributes, you can loop through the attributes() array:

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

Additional Note

Remember that attributes are accessed using the array syntax (['VarNum') rather than dot syntax.
