Введение

The "counter" extension provides any number of counters to PHP code using it which reset at times determined by the caller.

There are three interfaces to "counter": basic, extended, and objective. The basic interface provides a single counter controlled by INI settings and function calls. The extended interface provides an arbitrary number of named counter resources which may optionally persist beyond the lifetime of a single PHP request. The objective interface combines both the basic and extended interfaces into a Counter class.
