Download the PHP package dkkoma/php-grpc-lite without Composer

On this page you can find all versions of the php package dkkoma/php-grpc-lite. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.

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?

Native QA codecov

php-grpc-lite is a source-built PHP extension aiming to be a drop-in replacement for official ext-grpc in selected client workloads.

Performance snapshot

Latest representative local benchmarks: 2026-05-14 for Spanner RPC shape, 2026-05-05 / 2026-05-06 for broader unary and streaming payload sweeps. Environment: Docker compose on OrbStack, Go gRPC test server, php-grpc-lite HTTP/2 transport vs official ext-grpc. These numbers are workload guidance, not a portability guarantee; rerun the benchmark suite on release hardware for final decisions. Full data: docs/benchmarks/spanner-shape-2026-05-14.md, docs/benchmarks/spanner-real-client-2026-05-14.md, docs/benchmarks/native-major-2026-05-05.md, and docs/benchmarks/native-hardening-2026-05-06.md.

spanner-shape is the primary Spanner-oriented performance signal because it keeps the RPC shape close to Spanner while avoiding emulator and GAX noise. spanner-real-client is kept as a high-level google/cloud-spanner smoke/regression benchmark rather than a transport microbenchmark.

Large bulk streaming remains the main case that should be measured against the actual workload before choosing this extension.

Install

Install build dependencies first. Debian/Ubuntu example:

Install the extension with PIE:

Then enable extension=grpc if PIE did not enable it automatically.

PIE uses Composer's default package download path. For this package, Composer prefers the Packagist/GitHub dist zip for the stable release. Ensure a zip extractor is available: unzip is the recommended Debian/Ubuntu package; PHP ext-zip or 7z can also satisfy Composer. Without any zip extractor, Composer falls back to source download and may require git.

Applications that use generated stubs or gax clients should also install the official PHP wrapper dependency with Composer:

For local source builds without PIE:

Full install notes, verification commands, rollback notes, and large-streaming guidance are in docs/guides/install-native-extension.md. The documentation entrypoint is docs/README.md.

Development

Run tests in Docker:

check-c-static-analysis.sh runs the C extension static analysis. check-c-unit.sh runs focused C unit tests for pure protocol helpers and status taxonomy. check-phpt.sh builds the root extension, verifies the local Go test-server ports, and runs PHPT tests for the extension surface, transport control semantics, TLS/mTLS, and resource limits. check-crash-ub.sh runs generated-input checks under ASan/UBSan to detect crashes and undefined behavior. check-c-coverage.sh runs the C unit and PHPT gates with gcov/lcov instrumentation and writes reports under var/coverage/c-lcov/. PHPUnit remains the broader integration/release compatibility suite.

GitHub Actions Native QA runs purpose-specific jobs on push and pull request: Static analysis, NTS PHPT + C coverage, ZTS PHPT, and Crash/UB check. Coverage is uploaded as a workflow artifact and to Codecov from var/coverage/c-lcov/codecov.info; configure CODECOV_TOKEN unless the Codecov repository setting allows tokenless public uploads.
