What is the best way to read the current content of an iframe in PHP?

To read the current content of an iframe in PHP, you can use the file_get_contents() function to retrieve the HTML content of the iframe's source URL. You will need to specify the URL of the iframe as the parameter for file_get_contents().

$iframe_url = "https://www.example.com/iframe";
$iframe_content = file_get_contents($iframe_url);
echo $iframe_content;
