Override

To override this PHP function, use this hook in your child theme or plugin ("my_custom" can be changed):

PHP

add_filter('pre_is_dev', 'my_custom_is_dev', 10, 2); //The last integer must be 1 more than the actual parameters
function my_custom_is_dev($null, $strict){ //$null is required, but can be ignored
    //Write your own code here

    return true; //Return true to prevent the original function from running afterwords
}

You can completely disable this PHP function with a single line actions:

PHP

 add_filter('pre_is_dev', '__return_false');
