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?

Informations about the package profiler

Componenta Profiler

Development-time profiler for request lifecycle, boot timing, service instrumentation, and timeline rendering.

Use this package as an optional development dependency. It is designed to be easy to disable in production: application code can depend on ProfilerInterface, while config decides whether the real profiler or a no-op integration is wired.

Installation

This package intentionally does not declare extra.componenta.config-providers. Register Componenta\Profiler\ConfigProvider manually from development-only application config when profiling is enabled.

Requirements

PHP 8.4+

Related Packages

Package	Why it matters here
`psr/http-message` / `psr/http-server-middleware`	Timing and profiler middleware work with PSR-7 requests, PSR-7 responses, and PSR-15 handlers.
`componenta/pipeline`	Profiling can wrap middleware pipelines.
`componenta/app`	Boot timing and early marks belong to the application lifecycle.
`componenta/di`	Service delegators can profile selected classes.

Core API

Marks are ordered records with labels, timestamps, memory usage, and type:

Point: instant marker
Begin: span start
End: span end

Early Bootstrap Marks

Marks is a process-global facade for points that happen before the DI container exists:

The application integration can merge these early marks into the configured ProfilerInterface.

Rendering

Renderers convert collected marks into formats useful for debugging:

JsonRenderer: structured machine-readable output.
ServerTimingRenderer: Server-Timing header value.
WaterfallRenderer: human-readable timeline.
CompositeRenderer: chooses among renderers.

HTTP And Framework Integration

The integration layer includes:

TimingMiddleware: marks PSR-15 request handling.
ProfilerMiddleware: exposes profiler output when a trigger matches.
TimingBootloader: records bootloader spans.
service delegators for profiling selected classes.
ProfilingPipelineFactory for wrapping middleware pipelines.

Triggers

Triggers decide whether profiling output should be enabled for a request:

query parameter trigger
header trigger
cookie trigger
composite trigger

This keeps profiling opt-in and avoids exposing profiler data by default.

DI Registration

ConfigProvider registers profiler services, renderers, triggers, and optional integration points. Keep the package dev-only unless the application has an explicit production observability use case.
