Get all the customer details by email id In Magento

<?php
$CustomerEmail = "customer@test.com";
$Customer = Mage::getModel("customer/customer");
$Customer->setWebsiteId(Mage::app()->getWebsite()->getId());
$Customer->loadByEmail($CustomerEmail); //load customer by email id
//use
echo $Customer->getId();
echo $Customer->getFirstName(); 
//print_r($customer->getData()); to find all the available elements.
?>

You can get the the Individual data by using the echo $Customer->getFirstName(); and you can display all the data by using the print_r(). It will returns all the available elements of the particuler customer for which you wants all the details.

Thanks and Happy coding.
