How to make calculations?

Hai all…
I’m new in using cakephp.
please help me…

i want to take the “id” value in users as a variable.
And SUM “id” value with “x” as new variable.

How to take “id” value as variable and create “x” variable, then SUM both values?

It is depend on your query. If it is CakePHP 3 you get a query object what is a collection and you can use collection method’s.

$x = $this->Users->find(‘all’)->where([‘’ => ‘$user->id’])

I hope this help!
