$date = Yii::$app->request->post('date');
$timestamp = strtotime($date);
var_dump($timestamp );
error
PHP Warning – yii\base\ErrorException
strtotime() expects parameter 1 to be string, array given
you should check you post for an array in $_POST('date')
in this case you could access at the value providing an index
$timestamp = strtotime($date[0]);

I am not able to get this otp parameter in smarty because it is ommiting + sign from url.
http://test.com/index.php?otp=+AU7Og==
I have used following code but not getting value +AU7Og== of otp parameter
{$smarty.get.otp|escape:html}
{$smarty.get.otp|escape:htmlall}
It's not a smarty problem. In the query of a URL, + represents a space. You'll have to encode the plus sign if you want to use it as part of a string parameter

I have a database with products.
I need to add to name of products some string.
Example:
product name "abc1", "abc2", "abc3"
new products name: "Super abc1", "Super abc2", "Super abc3"
Use MySQL's concat().
If you want to update :
update tablename set column=concat('Super ', column);
You can even add a where clause .
update player
set productName= concat("super ",productName)
You need to use CONCAT function
SELECT CONCAT('Super ',columnWithABc) from tab
