How to get customer data by id in Magneto 2

in this blog, we are going to how to get customer data by id using API repository and Factory Method

There are two ways to get customer data that you can use. You can also get its product data through customer data.

⇒ Using API Repository to Get Customer Data:

protected $_customerRepositoryInterface;

public function __construct(
    \Magento\Customer\Api\CustomerRepositoryInterface $_customerRepositoryInterface,
) {
    $this->_customerRepositoryInterface = $_customerRepositoryInterface;
}
$_customerId = 12;
$_customer = $this->_customerRepositoryInterface->getById($_customerId);

  $_customerFirstName = $_customer->getFirstName();
//$customerData = $_customer->getData();

protected $_customerRepositoryInterface;

public function __construct(

\Magento\Customer\Api\CustomerRepositoryInterface $_customerRepositoryInterface,

) {

$this->_customerRepositoryInterface = $_customerRepositoryInterface;

}

$_customerId = 12;

$_customer = $this->_customerRepositoryInterface->getById($_customerId);

$_customerFirstName = $_customer->getFirstName();

//$customerData = $_customer->getData();

⇒ Using Factory Method to Get Customer Data:

protected $_customer; 

 public function __construct(
 
 \Magento\Customer\Model\Customer $_customer

 ) {
 $this->_customer = $_customer;
 }

 public function getCustomerData()
 {
   $_customerId=22;
   $_customer = $this->_customer->create()->load($_customerId);
   //$customerData = $_customer->getData();
  return $_customer;
 }
}

protected $_customer;

public function __construct(

\Magento\Customer\Model\Customer $_customer

) {

$this->_customer = $_customer;

}

public function getCustomerData()

{

$_customerId=22;

$_customer = $this->_customer->create()->load($_customerId);

//$customerData = $_customer->getData();

return $_customer;

}

⇒ Call Phtml File:

$customerId = 1; //pass dynamic customer id
$Customer = $block->getCustomerData($customerId);
echo $Customer ->getFirstname(); // result customer first name
echo $Customer ->getEmail(); // result as customer email 
echo $Customer ->getLastname(); // customerr lastname

$customerId = 1; //pass dynamic customer id

$Customer = $block->getCustomerData($customerId);

echo $Customer ->getFirstname(); // result customer first name

echo $Customer ->getEmail(); // result as customer email

echo $Customer ->getLastname(); // customerr lastname

⇒ Using Object Manager:

$customerId=1;
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$customerData = $objectManager->create(‘Magento\Customer\Model\Customer’)->load($customerId);

$customerId=1;
