/*
Envia mail amb adjunts. Per enviar adjunts s'ha d'omplir l'array $attachments de forma adecuada;
Exemple:
$attachments[0]['name']='Nom per descarregar'
$attachments[0]['file']='ruta/de/larxiu'
$attagments[0]['type']= 'image/jpeg' O si volem enviar directament desde $_FILES
foreach($_FILES as $key => $value)
{
$attachments[$n][’file’] = $value[’tmp_name’];
$attachments[$n][’name’] = $value[’name’];
$attachments[$n][’content_type’] = $value[’type’];
$n++;
}
després només cal cridar la funció
send_mail(bill@microsoft.com, _BODY_, ‘Hi!’, ‘larry@google.com’, ‘Larry Page’,$attachments);
Nota: El body s’interpreta com HTML
Retorna 1 si s’ha enviat correctament
