What are the potential pitfalls of storing XML files in subdirectories in PHP?

Storing XML files in subdirectories in PHP can lead to potential pitfalls such as difficulty in locating and accessing the files, increased complexity in file management, and potential security vulnerabilities if directory permissions are not set correctly. To solve this issue, it is recommended to create a centralized directory for storing XML files and use a consistent naming convention to easily identify and access the files.

// Define a centralized directory for storing XML files
$xmlDirectory = 'xml_files/';

// Example of accessing an XML file named 'example.xml' in the centralized directory
$xmlFilePath = $xmlDirectory . 'example.xml';

// Load the XML file
$xml = simplexml_load_file($xmlFilePath);

// Process the XML data
foreach ($xml->children() as $child) {
    echo $child->getName() . ": " . $child . "<br>";
}
