A simple library containing a set of PHP helper methods, constants, and classes.

Setup and Command-Line Testing for Local Development

composer i
cp .rc.example .rc
cp .test.example .test
source .rc

Now, you can type devt in the terminal to run a simple local command-line test with Symfony-style output:

true # the result of Date::isLeapYear(2024);
