Historias de mi vida realSoy Jonathan Ramírez de Chile. En mi blog deseo contar mis vivencias personales, tips de desarrollo web, consejos de programación y datos curiosos de mi diario vivir.

Currently I have a resseller in a Chilean company that has web hosting services, the reseller is quite small and the main use I give you are personal developments as freelance developer. As been developing websites and platform management (CRM), also I have shared my space with some domains of known people, and in this same way has helped me pay the expenses of resseller, not so much what I charge, but if it helps me to pay and no money out of my pocket.

There are times when for various reasons the domain provider has to be ”down”, and oftenwork by topic I do not realize this, then to not have problems with my friends, and also to delivera “service” optimum, thought and research (Google) and create a domain ping returned me if the domain is working properly or was ”down”, there are a lot of code hanging around, but I wanted to create a painting and found me a simple exercise that works optimimanente and does what I require, which I share with you below:

/*
 * function valid if the domain is working properly
 * param: @dominio is string
 */
function ping($dominio){
    if(is_string($dominio)){
        $dato = @get_headers($dominio);
        if(is_array($dato)){
            return true;
        }else{
            return false;
        }
    }
}

Besides this, create an array of all my domains I need to monitor, and an array foreach and Itoured the domain asking for domain, if the function returns ”false”, send email notifying methat domain is down for revision . This obviously set a cronjob j0ny.cl in this field, I ammonitoring the notifications every 30 minutes, which will check if they consume significant bandwidth and hosting as a consequence of the reseller.

*
 * Function valid if the domain is working properly
 * Param: @dominio is string
 */
function ping($dominio){
    if(is_string($dominio)){
        $dato = @get_headers($dominio);
        if(is_array($dato)){
            return true;
        }else{
            return false;
        }
    }
}
/*
 * Array with a list of domains
 */
$dominios = array(
    'http://www.domain1.cl',
    'http://www.domain2.cl',
);
/*
 * Parameters to email headers
 */
$cabeceras  = 'MIME-Version: 1.0' . "\r\n";
$cabeceras .= 'Content-type: text/html; charset=utf-8' . "\r\n";
$cabeceras .= 'From: Boot Domain <domain@j0ny.cl>' . "\r\n";
// It covers all the domains, and notifies the email if anyone is down.
foreach ($dominios AS $retorno){
    if(!ping($retorno)){
        $asunto = 'Domain '.$retorno.' down';
        $mensaje = 'Look at!';
        if(mail('mail@domain.com', $asunto, $mensaje,$cabeceras)){
            echo 1;
        }
    }
}

I await your serve them, is quite basic, but good!

Until next time.
