It seems like $ch can also be of type false; however, parameter $ch of curl_setopt() does only seem to accept resource, maybe add an additional type check?

 If this is a false-positive, you can also ignore this issue in your code via the ignore-type   annotation

It seems like you do not handle an error condition for loadHTML(). This can introduce security issues, and is generally not recommended.
                                                                                                                                       (

 If this is a false-positive, you can also ignore this issue in your code via the ignore-unhandled   annotation

If you suppress an error, we recommend checking for the error condition explicitly:


// For example instead of
@mkdir($dir);

// Better use
if (@mkdir($dir) === false) {
    throw new \RuntimeException('The directory '.$dir.' could not be created.');
}
