function is_website_availible($url) {
    if (!filter_var($url, FILTER_VALIDATE_URL)){
        return false;
    }

    $curlInit = curl_init($url);
    
    curl_setopt($curlInit, CURLOPT_CONNECTTIMEOUT, 10);
    curl_setopt($curlInit, CURLOPT_HEADER, true);
    curl_setopt($curlInit, CURLOPT_NOBODY, true);
    curl_setopt($curlInit, CURLOPT_RETURNTRANSFER, true);

    $info = curl_exec($curlInit);
    
    curl_close($curlInit);

    return $info ? true : false;
}

$url = "https://www.collectivesolver.com/";

if (is_website_availible($url)) {
    echo "yes";
} else {
    echo "no"; 
}
