What are some potential methods for extracting data from a webpage using PHP?

One potential method for extracting data from a webpage using PHP is to use the file_get_contents() function to retrieve the HTML content of the webpage. Once the HTML content is obtained, you can use regular expressions or PHP DOMDocument to parse and extract the desired data from the webpage.

// URL of the webpage to extract data from
$url = 'https://www.example.com';

// Get the HTML content of the webpage
$html = file_get_contents($url);

// Use regular expressions to extract data from the HTML content
preg_match('/<title>(.*?)<\/title>/', $html, $titleMatches);
$title = $titleMatches[1];

echo $title;
