Learn from your fellow PHP developers with our PHP blogs, or help share the knowledge you've gained by writing your own.
I finally joined NomadPHP because in the current climate, I feel like I need to give back to the community, and share some of the things that I've learned over the years.

less
command in order to get pagination and search: php -i | less
. Type Q
