PHP5.6 SPL logical redeclaration

By historical reasons in PHP there is a big problem with functions naming. It's hard to remember functions names.

So, i try to structure functions and constants by related classes and namespaces.

N.B I tried ... :) But it is impossible to redeclarate following items:

Functions

• isset() //check variable definition in local scope
• unset() //delete variable link name in local scope
• get_defined_vars() //get all defined variables
• func_get_arg() //return function param by index
• func_get_args() //return function params by array
• func_num_args() //return number of params passed to a function

Constants

• _LINE_ //current executing file line
• _FILE_ //current executing file
• _DIR_ //current executing file dir
• _FUNCTION_ //current executing function
• _CLASS_ //current executing class (full - with namespace)
• _TRAIT_ //current executing trait (full - with namespace)
• _METHOD_ //current executing methode (full - with namespace)
• _NAMESPACE_ //current executing namespace

Because theare results and values depends on its location.
