Add PHP tutorials
I create a powerful and easy to use PHP library to interact with HIVE blockchain: hive-php-lib. I've made this with some considerations :
- Fully PHP-PDS and PSR standards compliance
- Fully Documented with DocBlocks (can generate API docs with phpDocumentor)
- Very easy to install (with Composer)
The goal is to create a full "Enterprise-class" PHP library with quality and clean code.
To use this lib, I want to write some documentation and this is the start of the official documentation. I've just change nav.yml and config.yml to add PHP in the collection. I've also add the PHP logo in images folder.
Please consider this merge request. Thank you very much.
