generatetoblock is an RPC for testing purposes. It is only expected to reliably work on test networks.

On the actual Bitcoin network, BTC cannot reasonably be mined using commodity hardware as the difficulty is far too high for that. Attempting to do so would earn you orders of magnitudes less than the cost of electricity and wear and tead to your hardware, so Bitcoin Core does not support doing so. You need custom hardware (called ASICs) to do that.

Fair point, it's not clear from the RPC documentation. I've opened #24028 to improve it.

To be clear: what this RPC does is perform 1000000 attempts at creating a valid block. If it can't succeed with that, it returns an error. It "works" the same way on mainnet too, it's just an incredible waste of time to try. You'd need 171 trillion calls on average to this RPC on average to construct a block at the current difficulty.

I'm planning on exploiting the target hash leading 0's with my own optimized script:

You won't ever mine any coins with this RPC or with PHP code, on mainnet.

Usually the issue tracker is used to track technical issues related to the Bitcoin Core code base. General bitcoin questions and/or support requests are best directed to the Bitcoin StackExchange or the #bitcoin IRC channel on Libera Chat.

Thanks for the report. The documentation will be updated in #24028. Though, I think general mining questions not related to the Bitcoin Core software are better answered elsewhere.
