I'm a PHP coder. I can also do C++. I work primarily with Linux servers for my coding. I'd like to build a PHP-based cart that can accept Litecoin. I've done cryptocurrency trading for a few years now, and talked to a few cryptocurrency APIs for getting rates and so on, but never have attempted adding a new transaction into a blockchain.
How does one add a new transaction into the blockchain with PHP and/or C++?
Or, if you think it's going to take me like a week of solid PHP and perhaps C++ coding to get a transaction into the blockchain, and could suggest a low-cost API that I should use instead, then please do so and I'll consider it.
