Retrieving XML Attribute Value in PHP
As showcased in the given inquiry, extracting data from an XML document can encounter challenges, particularly when obtaining attribute values. In this specific case, the task involves retrieving the "VarNum" attribute from an XML file.
Solution Implementation

$xml = simplexml_load_file($file); $attributes = $xml->Var[0]->attributes(); $varNum = $attributes['VarNum'];
Alternatively, you can simplify the code to directly access the attribute using the bracket notation:
$varNum = $xml->Var[0]['VarNum'];
By employing these methods, you can effortlessly obtain attribute values from your XML document, providing a straightforward and efficient solution for your data extraction needs.
