PHP functions implemented by Golang

This package implements some PHP functions by Golang. Please note that it's impossible to have 100% the same behaviour between PHP and Golang functions because their mechanisms are quite different.

Minimum go version requirement: 1.18, if you are using lower version, please choose version v0.63.
