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.

Informations about the package php-profiler

PHP profiler for short-term & long-term profiling

This tool allows you to monitor performance and detect memory leaks as well as inconsistent performance behavior of your application over time.

Basic profiling

For basic profiling you can use a profiling helper. The Profiling will allow you to profile between start and finish methods calls.

The Profiling is simple and cannot be turned on and off easily. So a profiler was created for the purpose of hard-coded more complex profiling.

Complex profiling

Request a profiler as a dependency and call a profile method on it.

How to enable / disable it

It can be easily enabled, or disabled through the DI, which provides either the NullProfiler.

Useful features

Take snapshot

If you need to measure the current values, just call the takeSnapshot method on the profiler.

If you want to automate it then take snapshot on tick. Or you can use a more practical cascade profiling.

Take snapshot on tick

For greater precision, you can take snapshot on each N tick.

This will result in very detailed code tracking, which can degrade the performance of the monitored application.

Cascade profiling

The profile method provides you a nested profiler that you can use for more detailed cascade profiling.
