Sort PHP array base on its value [duplicate]

Question

When I did

$result = array_count_values(Visitor::all()->pluck('device')->toArray());
$result = asort($result,SORT_NATURAL);
return $result;

I kept getting

The Response content must be a string or object implementing __toString(), "boolean" given.

This is an array

array_count_values(Visitor::all()->pluck('device')->toArray())

It returns

    Windows NT: 1,
    Linux 4.4.0-116-generic: 1
}

I want to sort them in a desc base on values.

Please help

asort() sorts the array in place, no need to resassign

asort() returns a boolean indicating whether the operation was successful or not. What you want to do instead is this :

$result = array_count_values(Visitor::all()->pluck('device')->toArray());
asort($result,SORT_NATURAL);

return $result;

See the documentation for more information

asort returns a boolean indicating if the sort was managed ok or not. It sorts the array by reference.

Change your code to:

$result = array_count_values(Visitor::all()->pluck('device')->toArray());
asort($result,SORT_NATURAL);
//$result is now sorted.
return $result;

asort() does not return the sorted array but a boolean to say if it's done (true) or not (false)

$result = array_count_values(Visitor::all()->pluck('device')->toArray());
asort($result, SORT_NATURAL);
return $result;

Use arsort(). It does the same as asort() but in reverse order.
