Laravel undefined variable when trying to pass data to view

I am trying to pass data from my controller to my view, but am getting an undefined variable error. usersID is a column in my MySQL table.

Here is the code in my controller 

$arrayWithCount = DB :: table("users_has_activities")
-> where("usersID", "=", 19)
-> pluck("usersID");

$countNumber = sizeof($arrayWithCount);

return view('pages.progress', ['countNumber' => $countNumber]);

I have also tried the following return statement without any success 

return view::make('pages.progress') -> with('countNumber', $countNumber);

I have also tried reversing the puck and where clauses without any success, I didn't have high hopes that reversing them would fix the problem but thought I would try it any way. Below is the relevant code in the blade file. 

 <?php echo $countNumber; ?>

This is the error I am currently getting 

Undefined variable: countNumber

You code looks fine, if dd() doesn't stop execution of the controller, then another controller is executing. So double check your routes and controllers.

I had all the controller code in a method I wasn't calling, so the variable was never passed to the blade file. The method was set up to be called on a button press, after fixing that everything works. Thanks Alexey for the help.

First sizeof should be sizeOf, and is simply an alias for count(). Most people would prefer count over sizeOf as sizeOf (in many languages) would indicate something related to size on disk.

Anywho, being that pluck returns a collection, you have access to count() directly from the collection.

You can probably simply do something like:

$countNumber = $arrayWithCount->count();

Sidenote: Unless there is a particular reason why you are using <?php ?>, in blade, it would be preferred to use {{ and }}.
