How can you check if a website exists using PHP?

To check if a website exists using PHP, you can use the `get_headers` function to send a HEAD request to the website URL and check the response code. If the response code is 200, then the website exists. 

function websiteExists($url){
    $headers = @get_headers($url);
    if($headers && strpos($headers[0], '200')){
        return true;
    } else {
        return false;
    }
}

// Example usage
$url = 'https://www.example.com';
if(websiteExists($url)){
    echo 'Website exists';
} else {
    echo 'Website does not exist';
}
