get result from database equal today

I need to get posts of today from database using where. 

PHP Code:

// Get Today Time
$time = Time::today('America/Chicago', 'en_US');
$today = $time->toDateString(); // 2021-02-05

$testModel = new \App\Models\TestModel();
$results = $testModel->getLatest($today); 


in Model (getLatest): 

PHP Code:

$builder = $this->db->table('posts p');
$builder->select('p.*');
$builder->where('???????????????',$today);
$builder->orderBy('created_at', 'ASC');
$prices = $builder->get()->getResultObject(); 


How do can I generate this query using where OR another method?

You can write custom where clause, see number 4 Custom string on this page: http://codeigniter.com/user_guide/databa...cific-data

Try this:

PHP Code:

$builder->where('created_at >= CURRENT_DATE'); 


If CI try to protect the field name and mess the query, try this:

PHP Code:

$builder->where('created_at >= CURRENT_DATE', null, false);
