How can one troubleshoot and debug issues related to object creation in PHP, specifically with DOMDocument?

Issue: When creating a new DOMDocument object in PHP, errors may occur due to incorrect usage or invalid input. To troubleshoot and debug these issues, ensure that the input data is valid and properly formatted, check for any syntax errors in the code, and use error handling techniques to catch and display any potential errors. 

// Example code snippet for troubleshooting and debugging object creation with DOMDocument

// Check for errors during object creation
libxml_use_internal_errors(true);

// Create a new DOMDocument object
$doc = new DOMDocument();

// Load XML content into the DOMDocument object
$doc->loadXML('<root><element>Example</element></root>');

// Check for any errors during the loading process
$errors = libxml_get_errors();
if (!empty($errors)) {
    foreach ($errors as $error) {
        echo "Error: " . $error->message . " at line " . $error->line . PHP_EOL;
    }
}

// Clear any errors and free memory
libxml_clear_errors();
libxml_use_internal_errors(false);
