In what scenarios would it be beneficial to use PHP to extract text from output layers?

When working with output layers in web development, you may need to extract text for various reasons such as data processing, content manipulation, or text analysis. PHP can be a useful tool for extracting text from output layers as it provides functions and libraries for parsing HTML and XML documents efficiently. By using PHP, you can easily navigate through the output layers, extract the desired text, and manipulate it as needed. 

<?php
// Sample code to extract text from an output layer using PHP

// Assume $output contains the HTML output layer
$output = "<div class='content'><p>Hello, World!</p></div>";

// Create a DOMDocument object to parse the HTML
$doc = new DOMDocument();
$doc->loadHTML($output);

// Use DOMXPath to query and extract text from specific elements
$xpath = new DOMXPath($doc);
$text = $xpath->query("//div[@class='content']/p")->item(0)->nodeValue;

echo $text; // Output: Hello, World!
?>
