Compatibility with php8.1

[Coolguy3289]

I know php8.1 is a breaking version, however upon an accidental upgrade, it was noted that for some reason the coin property aux_pow kept getting switch to "on" in the database. Some script that was running had been interpreted differently with 8.1 vs 7.4 causing this bug. Will need to investigate further what differences could cause this for future compatibilty
