coinspark-message v1.0
A simple PHP script to send and receive bitcoin transactions with CoinSpark messages
Copyright (c) Coin Sciences Ltd - http://coinspark.org/
MIT License (see headers in files)
REQUIREMENTS:
* Unix-based operating system, e.g. Linux or Mac OS X
* PHP 5.x or later
* bitcoin-cli installed (does not use JSON-RPC)
* Must be run as a user who is permitted to run bitcoin-cli
SENDING MESSAGES - USAGE ON THE COMMAND LINE:
* Ensure CONST_BITCOIN_CMD and CONST_BITCOIN_FEE in php-OP_RETURN.php are correct and check the other settings.
* php send-coinspark-message.php <send-address> <send-amount> <message-text> <testnet (optional)>
- <send-address> is the bitcoin address of the recipient
- <send-amount> is the amount to send (in units of BTC)
- <message-text> is the UTF-8 encoded message to be sent with the transaction
- <testnet> should be 1 to use the bitcoin testnet, otherwise it can be omitted
- Outputs an error if one occurred or the txid if sending was successful
* Examples:
php send-coinspark-message.php 149wHUMa41Xm2jnZtqgRx94uGbZD9kPXnS 0.001 'Here is some bitcoin for you.'
php send-coinspark-message.php mzEJxCrdva57shpv62udriBBgMECmaPce4 0.001 'Here is some testnet bitcoin for you!' 1
* Wait a few seconds then check http://coinsecrets.org/ to see your transaction.
RECEIVING MESSAGES - USAGE ON THE COMMAND LINE:
* Ensure CONST_BITCOIN_CMD in php-OP_RETURN.php is correct and check the other settings.
* php receive-coinspark-message.php <txid> <testnet (optional)>
- <txid> is the hexadecimal transaction ID of the transaction to be checked
- <testnet> should be 1 to use the bitcoin testnet, otherwise it can be omitted
- Outputs an error if one occurred or the message if it was successfully retrieved.
If the message is one piece of plain text with no filename (as created by this library)
then that text will be shown. Otherwise the full array of message parts will be shown.
* Examples:
php receive-coinspark-message.php bdb7b22c5a529a4feff994f8886123c793113a0c89d61fa72ffa0d3276a690df
php receive-coinspark-message.php 3c62230aa2022b4213a72782b269b4a9e9fdb4965ca345cdf830a2f3aeccafad 1
SENDING MESSAGES - USAGE AS A LIBRARY:
* Ensure CONST_BITCOIN_CMD and CONST_BITCOIN_FEE in php-OP_RETURN.php are correct and check the other settings.
* Include/require 'coinspark-message.php' in another script.
* coinspark_message_send($send_address, $send_amount, $message_text, $testnet=false)
- $send_address is the bitcoin address of the recipient
- $send_amount is the amount to send (in units of BTC)
- $message_text is the UTF-8 encoded message to be sent with the transaction
- $testnet is true/false whether to use the bitcoin testnet
- Returns: array('error' => '[some error string]') OR array('txid' => '[sent txid]')
* Wait a few seconds then check http://coinsecrets.org/ to see your transaction.
RECEIVING MESSAGES - USAGE AS A LIBRARY:
* Ensure CONST_BITCOIN_CMD in php-OP_RETURN.php is correct and check the other settings.
* Include/require 'coinspark-message.php' in another script.
* coinspark_message_receive($txid, $testnet=false)
- $txid is the hexadecimal transaction ID of the transaction to be checked
- $testnet is true/false whether to use the bitcoin testnet
- Returns: array('error' => '[some error string]') OR array('message' => full message parts array)
WHY NO WINDOWS SUPPORT?
There is an issue on Windows with the escapeshellarg() PHP function. A suitable
replacement is required which escapes shell argumentes safely and effectively.
The command line execution of bitcoin-cli could also be replaced by JSON-RPC calls.
