Please use this corrected version of function "valuesAreIdentical" instead of that which I previously posted (dependencies found in previous post); if an Admin can just replace the fn snippet, awesome/thanks, otherwise, apologies.
<?php
    public static function valuesAreIdentical($v1, $v2):bool{
        $type1 = gettype($v1);
        $type2 = gettype($v2);
        switch(true){
            case ($type1 !== $type2):
                return false;
            case ($type1==='boolean' || $type1==='integer' || $type1==='double' || $type1==='string'):
                //Do strict comparison here.
                return ($v1===$v2);
            case ($type1==='array'):
                return self::arraysAreIdentical($v1, $v2);
            case ($type1==='object'):
                return self::objectsAreIdentical($v1,$v2);
            case ($type1==='NULL'):
                //Since both types were of type NULL, consider their "values" equal.
                return true;
            case ($type1==='resource' || $type1==='unknown type'):
                //How to compare if at all?
                return true;
            default:
                return true; //Code-flow not intended to arrive here.             
        } //end switch
    }
?>
