On PHPMaster.com there's a new post by Michelle Sanver about The PHP People, a.k.a the PHP community, and some of the great resources you can use to get help on a problem or just reach out and meet some other PHP-ers in your area (or at a national conference!)
If you're ever stuck on a problem, Google it and you'll find a swarm of users have most likely experienced the same issue and have already shared their solution. If it's not out there, ask in a public forum and people will help you find the answer. And if you've managed to solve it yourself, then write about it! That way you'll be contributing to helping others the same way others are willing to help you. That's one part of the PHP community that makes it really stand out - people share their knowledge and are more than willing to help others along their journey with PHP.
Some resources/places to meet like-minded developers include:
The community in PHP is huge and is growing every day, and it's all about sharing. If you see someone in need and you're able to help, offer him guidance. If you see an open-source project that's great; contribute and help it grow.
