How do I call the BETWEEN function in php? - php

Question

I am trying to filter by date and status, in mysql the query is fine, but when implementing php it does not work for me.
My Consult Sql
SELECT `loan_items`.*
FROM `loan_items`
WHERE `date` BETWEEN '2023-03-10' AND '2023-03-10' AND `status` = 1;
Code Php
$date = date("y-d-m");
$this->db->select("li.id, c.dni, concat(c.first_name,' ',c.last_name) AS name_cst, l.id AS loan_id, li.pay_date, li.num_quota, li.fee_amount");
$this->db->from('loan_items li');
$this->db->join('loans l', 'l.id = li.loan_id', 'left');
$this->db->join('customers c', 'c.id = l.customer_id', 'left');
$this->db->where(['li.status' => 1, 'li.date' => "BETWEEN :$date AND :$date"]);
$this->db->order_by('li.pay_date', 'desc');
This way it works but it doesn't show me the date
$this->db->select("li.id, c.dni, concat(c.first_name,' ',c.last_name) AS name_cst, l.id AS loan_id, li.pay_date, li.num_quota, li.fee_amount");
$this->db->from('loan_items li');
$this->db->join('loans l', 'l.id = li.loan_id', 'left');
$this->db->join('customers c', 'c.id = l.customer_id', 'left');
$this->db->where('li.status', 1);
$this->db->order_by('li.pay_date', 'desc');
