FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Provided Examples

In the folder Examples/ there are some extended examples with call & send examples:

example.call.php
example.send.php
example.batch.php
example.account.php
example.contract_creation.php
example.erc20.php

Example configuration

To execute the examples you will need to add some data to the configuration file (example.config.php).

The example is pre-configured to work with an infura endpoint:

Just add your infura project keys. If you have not configured the api secret key requisite, just ignore it.

If you are using a private endpoint, just ignore all the infura definitions:

To enable contract interaction, set the contract data (address & ABI). The file is preconfigured to work with our example contract, already deployed on ropsten.

To enable transaction sending & signing, enter a valid pair of address and private key. Please take this advises before continuing:

The address must be active on the ropsten network and have some ether available to send the transactions.
Double check that you are using a test endpoint, otherwise you will be spending real eth to send the transactions
Be sure to keep your private key secret!

Example contract

The solidity contract used in this example is available too in the same folder: swp_contract.sol

Example disclaimer

Don't base your code structure on this example. This example does not represent clean / efficient / performant aproach to implement them in a production environment. It's only aim is to show some of the features of Simple Web3 Php.
