Information about built-in classes and functions from the command line

Maybe what I'm going to tell you is already known to all, or maybe not.

In general, this way: to get information about any built-in class or function (of course, this includes functions from any extension included in your assembly) - you can get this information using simple commands.



php --rc <class or interface>

$ php --rc Countable
Interface [  interface Countable] {
  - Constants [0] {
  }
  - Static properties [0] {
  }
  - Static methods [0] {
  }
  - Properties [0] {
  }
  - Methods [1] {
    Method [  abstract public method count] {
    }
  }
}

php --rf <function>

$ php --rf gettext
Function [  function gettext] {
  - Parameters [1] {
    Parameter # 0 [  $ msgid]
  }
}

In addition, the following features are also available:

php --re <extension> - information about the extension, its classes and functions.

php --ri <extension> - configuration of the selected extension
