+# gRPC PHP End-to-End Examples
+
+This page shows a number of ways to create a PHP gRPC client and connect with
+a gRPC backend service.
+
+
+## Run the Server
+
+For all the following examples, we use a simple gRPC server, written in Node.
+
+```sh
+$ git clone https://github.com/grpc/grpc-web
+$ cd grpc-web
+$ docker-compose build common node-server
+$ docker run -d -p 9090:9090 --name node-server grpcweb/node-server
+```
+
+
+## Install the gRPC PECL extension
+
+All the following commands are assumed to be run from this current directory.
+
+```sh
+$ cd grpc/examples/php/echo
+```
+
+
+In order to build a PHP gRPC client, we need to install the `grpc` extension
+first.
+
+```sh
+$ docker build -t grpc-php/base -f ./base.Dockerfile .
+```
+
+
+## CLI
+
+
+Let's first build a simple CLI gRPC client:
+
+```sh
+$ docker build -t grpc-php/echo-client -f ./cli.Dockerfile .
+$ docker run -it --rm --link node-server:node-server grpc-php/echo-client
+$ php client.php
+```
+
+
+
+## Apache
+
+
+Now let's see how the gRPC PHP client can run with Apache:
+
+```sh
+$ docker build -t grpc-php/apache -f ./apache.Dockerfile .
+$ docker run -it --rm --link node-server:node-server -p 80:80 grpc-php/apache
+```
+
+Open the browser to `http://localhost`.
+
+
+
+## Nginx + FPM
+
+
+We can also try running PHP-FPM and put Nginx in front of it.
+
+
+The PHP-FPM part:
+
+```sh
+$ docker build -t grpc-php/fpm -f ./fpm.Dockerfile .
+$ docker run -it --rm --link node-server:node-server -p 9000:9000 \
+  --name fpm grpc-php/fpm
+```
+
+The Nginx part:
+
+```sh
+$ docker run -it --rm -v $(pwd)/nginx.conf:/etc/nginx/conf.d/default.conf:ro \
+  --link fpm:fpm -p 80:80 nginx:1.17.4
+```
+
+
+Open the browser to `http://localhost`.

+# Docker Images for Testing
+
+This directory contains a number of docker images to assist testing the
+[gRPC PECL extension](http://pecl.php.net/package/grpc) against various
+different PHP environments.
+
+
+## Build and Run Tests
+
+To build all docker images:
+
+```sh
+# cd grpc
+$ ./src/php/bin/build_all_docker_images.sh
+
+# or to only build some selected images
+$ ./src/php/bin/build_all_docker_images.sh grpc-ext php-src
+
+# or to only print out individual `docker build` commands
+$ ./src/php/bin/build_all_docker_images.sh --cmds
+```
+
+
+To run all tests:
+
+```sh
+$ cd grpc
+$ ./src/php/bin/run_all_docker_images.sh
+
+# or to only run some selected images
+$ ./src/php/bin/run_all_docker_images.sh grpc-ext php-src
+
+# or to only print out individual `docker run` commands
+$ ./src/php/bin/run_all_docker_images.sh --cmds
+```
+
+
+## `grpc-ext`
+
+This image builds the full `grpc` PECL extension (effectively the current
+release candidate), installs it against the current PHP version, and runs the
+unit tests.
+
+
+## `grpc-src`
+
+This image builds the `grpc` PECL extension in a 'thin' way, only containing
+the gRPC extension source files. The gRPC C Core library is expected to be
+installed separately and dynamically linked. The extension is installed
+against the current PHP version.
+
+This also allows us to compile our `grpc` extension with some additional
+configure options, like `--enable-tests`, which allows some additional unit
+tests to be run.
+
+
+## `alpine`
+
+This image builds the `grpc` extension against the current PHP version in an
+Alpine-Linux base image.
+
+
+## `php-src`
+
+Instead of using a general purpose base docker image provided by PHP, here we
+compile PHP itself from
+[source](https://github.com/php/php-src). This will allow us to change some
+`configure` options, like `--enable-debug`. Then we proceed to build the full
+`grpc` PECL extension and run the unit tests.
+
+
+## `php-zts`
+
+This image builds the `grpc` extension against the current PHP version with ZTS
+enabled.
+
+
+## `php-future`
+
+This image builds the `grpc` extension against the next future PHP version
+currently in alpha, beta or release candidate stage.
+
+
+## `php5`
+
+This image builds the `grpc` extension against a PHP 5 base image with ZTS
+enabled.
+
+NOTE: PHP 5.x has reached the end-of-life state and is no longer supported.
+
+
+## `fork-support`
+
+This image tests `pcntl_fork()` support and makes sure scripts using
+`pcntl_fork()` don't hang or crash.
