How can PHP developers efficiently extract unformatted text and content within specific HTML tags?

To efficiently extract unformatted text and content within specific HTML tags, PHP developers can use the `strip_tags()` function to remove all HTML and PHP tags from a string, and then use `preg_match_all()` with a regular expression to extract the desired content within specific HTML tags. 

$html = '<div><p>This is some <strong>unformatted</strong> text.</p></div>';
$stripped_text = strip_tags($html); // Removes all HTML tags
preg_match_all('/<p>(.*?)<\/p>/', $html, $matches); // Extracts content within <p> tags
$content_within_p_tags = $matches[1][0]; // Accesses the extracted content
echo $content_within_p_tags; // Outputs: "This is some unformatted text."
