What are common challenges faced by beginners when using PHP for DOM manipulation?

Beginners often struggle with properly selecting DOM elements and manipulating them using PHP. One common challenge is understanding how to traverse the DOM tree and target specific elements. To solve this, beginners should familiarize themselves with PHP DOM functions like `getElementsByTagName()` and `getAttribute()` to access and modify elements. 

// Example code snippet for selecting and manipulating DOM elements using PHP
$html = '<div><p id="content">Hello, World!</p></div>';

$dom = new DOMDocument();
$dom->loadHTML($html);

// Select the <p> element with id "content"
$paragraph = $dom->getElementById('content');

// Update the text content of the selected <p> element
$paragraph->nodeValue = 'Goodbye, World!';

// Output the modified HTML
echo $dom->saveHTML();
