How can PHP be used to extract specific data from a given source code dynamically?

To extract specific data from a given source code dynamically using PHP, we can use regular expressions to search for patterns in the source code and extract the desired information. By defining the pattern we are looking for and using functions like preg_match() or preg_match_all(), we can extract the specific data we need. 

// Sample source code
$sourceCode = '<h1>Welcome to PHP</h1><p>This is a PHP tutorial</p>';

// Define the pattern to extract text within <h1> tags
$pattern = '/<h1>(.*?)<\/h1>/';

// Use preg_match() to extract the data
if (preg_match($pattern, $sourceCode, $matches)) {
    $extractedData = $matches[1];
    echo $extractedData; // Output: Welcome to PHP
}
