in laravel is posssible to store pressent time with pre-defined text in database,

i want to store present time and date along with pre-defined text in database,

like

"WELCOME 2019-12-10 16:06:36"

now it just storing date time only "2019-12-10 16:06:36"

i was tried but it showing error

"Object of class DateTime could not be converted to string"

my code

$user['hello'] = "welcome".new \DateTime('NOW');
