I have an array:
$data = array(
'loggedin' => false
);
i want to add other keys as well their values if the user is logged in so i use:
if ( $this->auth_model->loggedin()){//user is logged in
$data["loggedin"] = true;//set to true
$data["user_id"] = $this->session->userdata["uid"];//add new key with its value on $data array
}
is this the best way to do it or should i use array_push and such?
No need to add overhead by calling a function (like array_push).
Yes. That's the way to do it.
With array_push you cannot set the key.
The way you have described is the fastest one.
You can create a second array with user_id key and then merge those two arrays, but this is not a good way to solve this case.
Stay with that you have right now.
i don't think you can use array_push to add values to an associative array, so it's ok to do as you are doing
The way you are adding is better than using array_push (reason: you are inserting few values and it avoid the overhead of calling a function) if you are adding more values to this array, then you can use array_push.
array_push(). Also, speed does not really matter when you are adding two values to an almost empty array. Don't micro-optimize.
