What are the common pitfalls when trying to extract the title tag content from a webpage using PHP?

One common pitfall when trying to extract the title tag content from a webpage using PHP is not accounting for different variations of the title tag structure, such as including attributes like "id" or "class". To solve this, you can use regular expressions to search for the title tag content regardless of its attributes. 

// Get the webpage content
$html = file_get_contents('https://www.example.com');

// Use regular expressions to extract the title tag content
preg_match('/<title>(.*?)<\/title>/', $html, $matches);

// Output the title tag content
echo $matches[1];
