Bitcoin will begin synchronizing with the network and downloading a complete copy of the block chain. As of August , more than 2gb of data must be downloaded and verified during this process. It may take two or more hours to complete. You will know when it's done when the block count reaches the current count. The jsonRPCClient library uses fopen and will throw an exception saying "Unable to connect" if it receives a or error from bitcoind. This prevents you from being able to see error messages generated by bitcoind as they are sent with status or Bitcoin amounts can range from 1 Satoshi 0.
To avoid rounding errors, you must make sure your PHP implementation supports the full range of Bitcoin values without losing precision.
Most PHP implementations use IEEE bit double-precision floating point numbers with 53 bits of precision, which is enough to correctly represent the full range of bitcoin values. If your PHP implementation does not support bit numbers again, this is very rare , you must use a version of bitcoind that sends values as strings genjix maintains a fork at http: In Bitcoin, money is sent to addresses and many addresses can be held by one wallet.
The balance shown by default in bitcoind is the sum of the bitcoins in all the addresses in the wallet. Bitcoin goes another step. You can have accounts. Each account holds multiple addresses and acts like a mini-bitcoind. In your application, each user should have a unique username. The 4 indicates the minimum number of confirmations we will accept before assuming this payment is valid.
If you will be using accounts for multiple deposits and withdrawals long-term, you may want to consider tracking user balances in your own database. This simplifies transfers between your application's accounts and decouples your accounts from the Bitcoin wallet.
Using getnewaddress helps increase maintain anonymity of your users by making it hard for a malicious agent to track payments flowing through your application. It may take two or more hours to complete. You will know when it's done when the block count reaches the current count.

Running getnewaddress too often, however, will cause your wallet to become filled with many empty addresses. It is therefore recommended to in some way limit the number of unfunded addresses each user can request.
