PHP tool to create Ethereum raw transaction

Pre-requisite

secp256k1-php

You need secp256k1-php. Which itself needs secp256k1 to be installed on your system.

Last tests were run using the following versions :

• secp256k1-lastest
• secp256k1-php-0.1.2

You will need gcc, libtool, make, automake , which is standard package you can grab from apt, yum, brew...

First install secp256k1

$> curl -L0k https://github.com/bitcoin-core/secp256k1/archive/master.zip > secp256k1-latest.zip
$> unzip secp256k1-latest.zip
$> cd secp256k1-master
$> ./autogen.sh
$> ./configure --enable-experimental --enable-module-{ecdh,recovery}
$> make
$> sudo make install
$>

Then secp256k1-php

$> curl -L0k https://github.com/Bit-Wasp/secp256k1-php/archive/v0.1.2.zip > secp256k1-php-0.1.2.zip
$> unzip secp256k1-php-0.1.2.zip
$> cd secp256k1-php-0.1.2/secp256k1
$> phpize

Finally add extension to you php.ini file

extension=secp256k1.so
