+
+#Overview
+
+This directory contains source code for PHP implementation of gRPC layered on shared C library.
+
+#Status
+
+Beta
+
+## Environment
+
+Prerequisite: `php` >=5.5, `phpize`, `pecl`, `phpunit`
+
+**Linux (Debian):**
+
+```sh
+$ sudo apt-get install php5 php5-dev php-pear
+```
+
+**Linux (CentOS):**
+
+```sh
+$ yum install php55w
+$ yum --enablerepo=remi,remi-php55 install php-devel php-pear
+```
+
+**Mac OS X:**
+
+```sh
+$ curl -O http://pear.php.net/go-pear.phar
+$ sudo php -d detect_unicode=0 go-pear.phar
+```
+
+**PHPUnit:**
+```sh
+$ wget https://phar.phpunit.de/phpunit-old.phar
+$ chmod +x phpunit-old.phar
+$ sudo mv phpunit-old.phar /usr/bin/phpunit
+```
+
+## Quick Install
+
+Install the gRPC PHP extension
+
+```sh
+sudo pecl install grpc-beta
+```
+
+This will compile and install the gRPC PHP extension into the standard PHP extension directory. You should be able to run the [unit tests](#unit-tests), with the PHP extension installed.
+
+To run tests with generated stub code from `.proto` files, you will also need the `composer`, `protoc` and `protoc-gen-php` binaries. You can find out how to get these [below](#generated-code-tests).
+
+## Build from Source
+
+
+### gRPC C core library
+
+Clone this repository
+
+```sh
+$ git clone https://github.com/grpc/grpc.git
+```
+
+Build and install the gRPC C core library
+
+```sh
+$ cd grpc
+$ git pull --recurse-submodules && git submodule update --init --recursive
+$ make
+$ sudo make install
+```
+
+### gRPC PHP extension
+
+Install the gRPC PHP extension from PECL
+
+```sh
+$ sudo pecl install grpc-beta
+```
+
+Or, compile from source
+
+```sh
+$ cd grpc/src/php/ext/grpc
+$ phpize
+$ ./configure
+$ make
+$ sudo make install
+```
+
+### Update php.ini
+
+Add this line to your `php.ini` file, e.g. `/etc/php5/cli/php.ini`
+
+```sh
+extension=grpc.so
+```
+
+## Unit Tests
+
+You will need the source code to run tests
+
+```sh
+$ git clone https://github.com/grpc/grpc.git
+$ cd grpc
+$ git pull --recurse-submodules && git submodule update --init --recursive
+```
+
+Run unit tests
+
+```sh
+$ cd grpc/src/php
+$ ./bin/run_tests.sh
+```
+
+## Generated Code Tests
+
+This section specifies the prerequisites for running the generated code tests, as well as how to run the tests themselves.
+
+### Composer
+
+If you don't have it already, install `composer` to pull in some runtime dependencies based on the `composer.json` file.
+
+```sh
+$ curl -sS https://getcomposer.org/installer | php
+$ sudo mv composer.phar /usr/local/bin/composer
+
+$ cd grpc/src/php
+$ composer install
+```
+
+### Protobuf compiler
+
+Again if you don't have it already, you need to install the protobuf compiler `protoc`, version 3.0.0+.
+
+If you compiled the gRPC C core library from source above, the `protoc` binary should have been installed as well. If it hasn't been installed, you can run the following commands to install it.
+
+```sh
+$ cd grpc/third_party/protobuf
+$ sudo make install   # 'make' should have been run by core grpc
+```
+
+Alternatively, you can download `protoc` binaries from [the protocol buffers Github repository](https://github.com/google/protobuf/releases).
+
+
+### PHP protobuf compiler
+
+You need to install `protoc-gen-php` to generate stub class `.php` files from service definition `.proto` files.
+
+```sh
+$ cd grpc/src/php/vendor/datto/protobuf-php # if you had run `composer install` in the previous step
+
+OR
+
+$ git clone https://github.com/stanley-cheung/Protobuf-PHP # clone from github repo
+
+$ gem install rake ronn
+$ rake pear:package version=1.0
+$ sudo pear install Protobuf-1.0.tgz
+```
+
+### Client Stub
+
+Generate client stub classes from `.proto` files
+
+```sh
+$ cd grpc/src/php
+$ ./bin/generate_proto_php.sh
+```
+
+### Run test server
+
+Run a local server serving the math services. Please see [Node][] for how to run an example server.
+
+```sh
+$ cd grpc
+$ npm install
+$ nodejs src/node/test/math/math_server.js
+```
+
+### Run test client
+
+Run the generated code tests
+
+```sh
+$ cd grpc/src/php
+$ ./bin/run_gen_code_test.sh
+```
+
+## Use the gRPC PHP extension with Apache
+
+Install `apache2`, in addition to `php5` above
+
+```sh
+$ sudo apt-get install apache2
+```
+
+Add this line to your `php.ini` file, e.g. `/etc/php5/apache2/php.ini`
+
+```sh
+extension=grpc.so
+```
+
+Restart apache
+
+```sh
+$ sudo service apache2 restart
+```
+
+Make sure the Node math server is still running, as above. 
+
+```sh
+$ cd grpc
+$ npm install
+$ nodejs src/node/test/math/math_server.js
+```
+
+Make sure you have run `composer install` to generate the `vendor/autoload.php` file
+
+```sh
+$ cd grpc/src/php
+$ composer install
+```
+
+Make sure you have generated the client stub `math.php`
+
+```sh
+$ ./bin/generate_proto_php.sh
+```
+
+Copy the `math_client.php` file into your Apache document root, e.g.
+
+```sh
+$ cp tests/generated_code/math_client.php /var/www/html
+```
+
+You may have to fix the first two lines to point the includes to your installation:
+
+```php
+include 'vendor/autoload.php';
+include 'tests/generated_code/math.php';
+```
+
+Connect to `localhost/math_client.php` in your browser, or run this from command line:
+
+```sh
+$ curl localhost/math_client.php
+```
+
+## Use the gRPC PHP extension with Nginx/PHP-FPM
+
+Install `nginx` and `php5-fpm`, in addition to `php5` above
+
+```sh
+$ sudo apt-get install nginx php5-fpm
+```
+
+Add this line to your `php.ini` file, e.g. `/etc/php5/fpm/php.ini`
+
+```sh
+extension=grpc.so
+```
+
+Uncomment the following lines in your `/etc/nginx/sites-available/default` file:
+
+```
+location ~ \.php$ {
+    include snippets/fastcgi-php.conf;
+    fastcgi_pass unix:/var/run/php5-fpm.sock;
+}
+```
+
+Restart nginx and php-fpm
+
+```sh
+$ sudo service nginx restart
+$ sudo service php5-fpm restart
+```
+
+Make sure the Node math server is still running, as above. 
+
+```sh
+$ cd grpc
+$ npm install
+$ nodejs src/node/test/math/math_server.js
+```
+
+Make sure you have run `composer install` to generate the `vendor/autoload.php` file
+
+```sh
+$ cd grpc/src/php
+$ composer install
+```
+
+Make sure you have generated the client stub `math.php`
+
+```sh
+$ ./bin/generate_proto_php.sh
+```
+
+Copy the `math_client.php` file into your Nginx document root, e.g.
+
+```sh
+$ cp tests/generated_code/math_client.php /var/www/html
+```
+
+You may have to fix the first two lines to point the includes to your installation:
+
+```php
+include 'vendor/autoload.php';
+include 'tests/generated_code/math.php';
+```
+
+Connect to `localhost/math_client.php` in your browser, or run this from command line:
+
+```sh
+$ curl localhost/math_client.php
+```
