Laravel Eloquent unable to read data from databse table columns with numerical column names

I have a mysql table used for a Laravel model. The table contains some columns whose names are purely numeric, i.e. contain only numbers which are years. Please see image attached below.

When I query the table using eloquent the result results returned are missing the numerical column names. Even though the values are returned, the column names are deformed and display as single digit numbers.

When using accessors, I'm able to return the columns with friendly names however I am not able to update the model columns.

So my questions are

1. What is the best way to read and update the columns?
2. I'm not able to change the column names so the only option is to find a work around in my laravel code.

I guess this is because you can't name php variables with names starting with a number.

So to update the value you will need to write setters in addition to your getters. You should be able to do that with Eloquent accessors and mutators.

Edit: After some test, I didn't find how to do it with accessors and mutators, but I came up with another solution who might be working given Tim Lewis's comment.

public function setYear($yearColumnName, $value)
{
    $this->{$yearColumnName} = $value;
}
