Argon2i password hash algorithm is not working in php?

Question

I am learning api development with php now. While experimenting the password hashing i came up with a problem.

Initally i used bcrypt algorithm, it successfully works, but when i tried Argon2i or Argon2id it throws an error.

public function test_hash() {
    if(isset($this->_request['pass'])) {
        $hash = password_hash($this->_request['pass'], '2y', array('cost' => 10));
        
        $input = "password";

        if(password_verify($input, $hash)) {
            echo "True" . "\n";
        } else {
            echo "False" . "\n";
        }

        $data = array("password" => $this->_request['pass'], "hashed pwd" => $hash);
        $data = $this->json($data);

        $this->response($data, 200);
    }
}

for this : http://localhost/api/test_hash?pass=password

I get resposnse as :

True
{
    "password": "password",
    "hashed pwd": "$2y$10$4M4qHHSN6S0y7h6xyW6XCuRNhW44xRFN5EjnHNTPZKzuBeXXHMe0e"
}

When i try Argon2i it doesn't works... i replaced the following line

$hash = password_hash($this->_request['pass'], 'argon2i');

i get response as...

500 Internal Server Error

I also checked for available algorithms...

php > $info = password_algos();
php > print_r($info);
Array
(
    [0] => 2y
    [1] => argon2i
    [2] => argon2id
)
