php if conditions in regex [closed]

I wrote something like this:

   private function addDefaultConfiguration(): void
    {
        $specialNameKeys = ['name1Id', 'name2Id', 'name3Id', 'name4Id'];
        $specialAgeKeys = ['age1Id', 'age2Id', 'age3Id', 'age4Id'];

        foreach ((new PersonStruct())->jsonSerialize() as $key => $value) {
            if (in_array($key, $specialNameKeys)) {
                $value = $this->getNameRandomId();
            }

            if (in_array($key, $specialAgeKeys)) {
                $value = $this->getAgeRandomId();
            }
        }
    }

but I'm sure this if can be written better. I'd love to use regex for this, but I have no idea how.
