Question

I am writing a script to install the database of an application in php. It working fine but when im trying to install a database that doesnt exist i want only my own error message but i keep getting the default Warning : Warning: mysqli::mysqli() [mysqli.mysqli]: (HY000/2005): Unknown MySQL server host ‘kasdasd’.

So I know that the host is wrong and I want it to be so, with only my own errormessage. How do I get rid of this message?

My connectclass with parameter DBConfig $config:

    $this->mysqli = new mysqli($config->m_host,
                                $config->m_user,
                                $config->m_passw,
                                $config->m_db);

    if ($this->mysqli->connect_error) {
        return false;
    }

    $this->mysqli->set_charset("utf8");

    return true;

an easy solution would be to see if you can open the hostname using fsockopen and suppressing the errors:

$port = 80;

if($fp = @fsockopen($config->m_host,$port)){
    $db = new mysqli($config->m_host,$config->m_user,$config->m_passw,$config->m_db);
}else{
    echo 'hostname not recognized';
}
@fclose($fp);
