+# Namespace helper - create `use Namespace;` Statements
 
+This package can parse PHP scripts to extract the names of Classes, Functions and Constants used within the script. The parsed names will then be used to generate a list of `use Namespace;` statements for the parsed script. It can parse any script, but only namespaced Classes allows the use of the generated statements.

 It's pretty hard to talk about this Topic, because it's just called "Namespace" ...

-The `use` keyword can be used within Classes to tell PHP, which Classes, Functions and Constants to use internally for Functions used in your Class. It also can boost your scripts by pointing PHP to the right Namespace to use. For example, if you call `json_encode()` within a Class, PHP searches in the calling Class for a Function with the name `json_encode()` first, before searching it in the global Namespace (if at all). You can speed up the process with a Backslash before the function name, like: `\json_encode()`, but IDK, it looks awful. An alternate is to define any used Function, Class and Constant at the very top of your Class with the 'use'-keyword. And that's for what this Package is meant to be.
