Hello,
I have been a PHP developer for a decade or so.
I am interested in contributing to open source projects.
I want projects that are popular but still need a lot of contribution.
Contributing to Drupal modules or underlying (symfony and other) libraries is very fulfilling. And the conferences are really nice (and big) with lots of interesting people there with all sorts of problems.
There is all kinds of difficult there if you like difficult.
Moodle is a popular open source LMS (learning management system) written in PHP that could use a ton of improvement, especially on the front end. It's not necessarily bad, but it is very outdated compared to offerings by private companies.
Are there any specific libraries or tools written in PHP that you use in your day-to-day life? Perhaps having a look into their state could yield some interesting opportunities for you to contribute. That way you'd also get an extra incentive to keep contributing, as you'd personally get to enjoy the results, too.
There's a lot of open source PHP projects. Type a random word relating to one of your interests into https://packagist.org and you'll likely find several.
