#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):

$ sudo apt-get install php5 php5-dev php-pear

Linux (CentOS):

$ yum install php55w
$ yum --enablerepo=remi,remi-php55 install php-devel php-pear

Mac OS X:

$ curl -O http://pear.php.net/go-pear.phar
$ sudo php -d detect_unicode=0 go-pear.phar

PHPUnit:

$ 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

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, 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.

Build from Source

gRPC C core library

Clone this repository

$ git clone https://github.com/grpc/grpc.git

Build and install the gRPC C core library

$ 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

$ sudo pecl install grpc-beta

Or, compile from source

$ 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

extension=grpc.so

Unit Tests

You will need the source code to run tests

$ git clone https://github.com/grpc/grpc.git
$ cd grpc
$ git pull --recurse-submodules && git submodule update --init --recursive

Run unit tests

$ 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.

$ 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.

$ 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.

PHP protobuf compiler

You need to install protoc-gen-php to generate stub class .php files from service definition .proto files.

$ 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

$ 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.

$ cd grpc
$ npm install
$ nodejs src/node/test/math/math_server.js

Run test client

Run the generated code tests

$ cd grpc/src/php
$ ./bin/run_gen_code_test.sh

Use the gRPC PHP extension with Apache

Install apache2, in addition to php5 above

$ sudo apt-get install apache2

Add this line to your php.ini file, e.g. /etc/php5/apache2/php.ini

extension=grpc.so

Restart apache

$ sudo service apache2 restart

Make sure the Node math server is still running, as above.

$ 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

$ cd grpc/src/php
$ composer install

Make sure you have generated the client stub math.php

$ ./bin/generate_proto_php.sh

Copy the math_client.php file into your Apache document root, e.g.

$ 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:

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:

$ curl localhost/math_client.php

Use the gRPC PHP extension with Nginx/PHP-FPM

Install nginx and php5-fpm, in addition to php5 above

$ sudo apt-get install nginx php5-fpm

Add this line to your php.ini file, e.g. /etc/php5/fpm/php.ini

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

$ sudo service nginx restart
$ sudo service php5-fpm restart

Make sure the Node math server is still running, as above.

$ 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

$ cd grpc/src/php
$ composer install

Make sure you have generated the client stub math.php

$ ./bin/generate_proto_php.sh

Copy the math_client.php file into your Nginx document root, e.g.

$ 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:

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:

$ curl localhost/math_client.php
