I would start at this: https://github.com/Bit-Wasp/bitcoin-lib-php/blob/master/examples/raw_transaction.php get the information about the transaction, then create/sign it.

Then do:
$rpc = new JsonRpcClient(array("url"=>"bitcoinrpc:password@127.0.0.1:port")); $sentTxid = $rpc->sendrawtransaction($transactionHex);
BTW odds are if your transaction is rejected (error code -25? but no message) you had passed a tx with an 'insanely high fee'. You can override this check by doing sendrawtransaction($transactionHex, true) I think..

bitcoin-cli help will probably help here, all the RPC functions are as described on that page.

@coingeek you need to add a 'change output' yourself sending the other 4.5 coin back to your own address or to a new address of yourself

Yeah you need to be explicit about the amounts that you're moving.

When you make a transaction, there is actually nothing in the tx that restricts it to a network. so to answer what parameters you need to change, just be sure you explicitly set your version bytes address/p2sh, and if you're creating a coin please stick to the convention of the private key being AddressVersion + 128. There is a reason it's done that way in bitcoin, and this library depends on that to derive the private key's WIF.

I Generate the same public key from my private key using your library, so i think it is ok,
but the problem when i generate the tx, it, the network report it as (error -22),

I'm going to close this, think the problems are mainly due to using an older altcoin.
