PHP,CURL:函数获取响应代码并返回变量

I have the following function:

function file_get_contents_curl($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_USERAGENT, random_user_agent());
    curl_setopt($ch, CURLOPT_HTTPHEADER, 'Content-type: text/plain');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

I need to have some logic inside this function that if the response code of the URL is for example 404, then return null $data variable. I made an example of what I am looking for:

function file_get_contents_curl($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_USERAGENT, random_user_agent());
    curl_setopt($ch, CURLOPT_HTTPHEADER, 'Content-type: text/plain');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    $data = curl_exec($ch);

    if (empty($data) or (HTTP response code is 404)) {
        // some kind of an error happened
        die(curl_error($ch));
        curl_close($ch); 
        $data = null;
        return $data;
    } else {
        // everything  is ok
        return $data;

    }
}

    function file_get_contents_curl($url) {
                $ch = curl_init();
                curl_setopt($ch, CURLOPT_USERAGENT, random_user_agent());
                curl_setopt($ch, CURLOPT_HTTPHEADER, 'Content-type: text/plain');
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
                curl_setopt($ch, CURLOPT_URL, $url);
                $data = curl_exec($ch);
    
                if (empty($data) OR (curl_getinfo($ch, CURLINFO_HTTP_CODE == 404))) {
                        // some kind of an error happened
                        die(curl_error($ch));
                        curl_close($ch); 
                        $data = null;
                        return $data;
                    } else {
                        // everything  is ok
                        return $data;
    
                    }
    
            }

    use curl_getinfo($ch) before curl_close() called
