A Major Event in PHP
A Major Event in PHP
A thorough introduction to PSR-14: The Event Dispatcher standard.
About the Book
In early 2019, the PHP Framework Interoperability Group (PHP-FIG) released PSR-14, the Event Dispatcher specification. At the time I posted a long series of blog posts detailing PSR-14 in all its glory.
This book is those blog posts, collected into a single ebook format and lightly edited to fit better in book format. The blog posts are still available and will remain so, but this is for those that prefer their FIG in ebook format, or who want to support the work of FIG and Open Sourcing Mental Illness (https://osmihelp.org/).
OSMI is a non-profit organization that works to raise awareness of and research information about mental health challenges in the tech community. 50% of all royalties for this book are automatically donated to OSMI to support their vital work.
