What is the best approach to extracting content from unknown structured data in PHP?

When dealing with unknown structured data in PHP, the best approach is to use a combination of regular expressions and DOM parsing to extract the desired content. Regular expressions can help identify patterns in the data, while DOM parsing can be used to navigate and extract specific elements from HTML or XML documents. 

// Sample code snippet for extracting content from unknown structured data in PHP

// Assume $unknownData contains the unknown structured data

// Use regular expressions to extract specific content based on patterns
preg_match('/<title>(.*?)<\/title>/', $unknownData, $titleMatches);
$title = $titleMatches[1]; // Extract the title from the data

// Use DOM parsing to extract specific elements from HTML or XML data
$doc = new DOMDocument();
$doc->loadHTML($unknownData);

// Extract all <p> elements from the data
$paragraphs = $doc->getElementsByTagName('p');
foreach ($paragraphs as $paragraph) {
    echo $paragraph->nodeValue . "\n"; // Output each paragraph content
}
