This list is my personal top 10 list of PHP projects that have no financial backup or support which deserves credits. I've also included my motivation as reference.
- Composer: It revolutionised PHP world by allowing people to build awesome components supported by major frameworks and tools
- PHPUnit: Since it was ported to PHP it added quality and easy maintenance to a lot of projects
- XDebug: This tool has offered developers a chance to analyse their code step by step to find bugs or solve coding mysteries
- Slim Framework: A true PHP microframework
- Phing: The PHP build tool
