FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Overview
This class/trait allows you to traverse the debug_backtrace() to find out what the calling class/function or the calling namespace is. This is useful in cases where you need to find out at runtime in what context a given method was called.
Installation
The best way to install this package is through Composer:
Basic Usage
Setting Things Up
To create a new class that can fetch the caller's name or namespace, you can either extend the BrightNucleus\NamespaceBacktracer\NamespaceBacktracerClass class or, should you already have a class you need to extend, you can import the BrightNucleus\NamespaceBacktracer\NamespaceBacktracerTrait trait.
In both cases you'll want to override one or more of the three methods that allow you to adapt the behavior to your environment:
getIgnoredInterfaces()
This gets the list of interfaces/classes to ignore while traversing the backtrace.
getIgnoredFunctions()
This gets the list of functions to ignore while traversing the backtrace.
getGlobalNamespace()
This defines by what string the global namespace is represented.
Making The Call
To get the caller's namespace for a specific call, you pass the output of debug_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS) that was executed from within the callee to the getCallingNamespace() method. If you don't provide a debug_backtrace output, it will get fetched within the trait (which might be a different context than the one you want to check).
