Hello Developers,
When I was started working in magento. i found so many problem in custom development in
magento. i tried so many times for google those things. When you are working with customer module
then you need to know everything about magento customer collection.
some time you want to add new customer programmatically on magento store. most of developer
add customers on store using programmically becasue it is so fast and easy for them.

Your can try this code to create new customer in magento store.


$website_Id = Mage::app()->getWebsite()->getId();
$store_id = Mage::app()->getStore();
$new_customer = Mage::getModel("customer/customer");
$new_customer   ->setWebsiteId($websiteId)
            ->setStore($store_id)
            ->setFirstname('star')
            ->setLastname('Gennius')
            ->setEmail('stargenius@w3chacking.com')
            ->setTelephone('0987656532')
            ->setStreet('New Delhi')
           ->setCountry('India');
 
try{
    $new_customer->save();
}
catch (Exception $e) {
    Zend_Debug::dump($e->getMessage());
}

If you want to setup auto password then just use this code instead of password in abobe
code.
  $customer->setPassword($customer->generatePassword($pwd_length));

 $website_Id = Mage::app()->getWebsite()->getId();
$store_id = Mage::app()->getStore();
$new_customer = Mage::getModel("customer/customer");
$new_customer   ->setWebsiteId($websiteId)
            ->setStore($store_id)
            ->setFirstname('star')
            ->setLastname('Gennius')
            ->setEmail('stargenius@w3chacking.com')
            ->setTelephone('0987656532')
            ->setStreet('New Delhi')
           ->setCountry('India')
            ->setConfirmation(0)
            ->sendNewAccountEmail(0);

try{
    $new_customer->save();
}
catch (Exception $e) {
    Zend_Debug::dump($e->getMessage());
}
