FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

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 PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • 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.
Please rate this library. Is it a good library?

Basic Usage

Example setup

Example bootstrap/app.php file:

Tracing

To trace a specific process in your application you can wrap the process in a trace closure using the provided facade as shown below. This will take care of starting a new trace span and closing it again when the closure either returns or throws.

Nested traces are also possible like below. It will automatically take care of the span child/parent relations.

If you want to add context information or tags to your spans, it is possible like below.

Helper functions are provided for all functions available on the facade.

Common Tags

This package provides resolvers for common tags from a given context such as an Eloquent Query Builder, Request object, or Response object. These can be overridden in configuration like below.

There are helper functions available for deriving tags from contexts based on the current configuration.

Tracing Jobs

All jobs can be automatically traced by using the enable_jobs boolean in the configuration file or for tracing on certain jobs, attach the provided middleware to the ones you wish to trace.

Tracing Across Service Boundaries

Trace contexts can easily be used across services. If your application starts a tracing context, that context can be carried over HTTP to another service with an OpenTracing compatible implementation.

To automatically accept trace contexts from other services, add the tracing middleware to your application by adding it to your app/Http/Kernel.php file like below:

Assuming your application uses GuzzleHttp for sending requests to external services, you can use the provided tracing handler when creating the client like below. This will automatically send the necessary trace context headers with the HTTP request to the external service.

Testing
