#Overview

This directory contains source code for PHP implementation of gRPC layered on shared C library.

#Status

Beta

Environment

Prerequisite: PHP 5.5 or later, phpunit, pecl

Linux:

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

Mac OS X:

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

PHPUnit: (Both Linux and Mac OS X)

$ curl https://phar.phpunit.de/phpunit.phar -o phpunit.phar
$ chmod +x phpunit.phar
$ sudo mv phpunit.phar /usr/local/bin/phpunit

Quick Install

Linux (Debian):

Add Debian jessie-backports to your sources.list file. Example:

echo "deb http://http.debian.net/debian jessie-backports main" | \
sudo tee -a /etc/apt/sources.list

Install the gRPC Debian package

sudo apt-get update
sudo apt-get install libgrpc-dev

Install the gRPC PHP extension

sudo pecl install grpc-beta

Mac OS X:

Install homebrew. Example:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install the gRPC core library and the PHP extension in one step

$ curl -fsSL https://goo.gl/getgrpc | bash -s php

This will download and run the gRPC install script and compile the gRPC PHP extension.

Build from Source

Clone this repository

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

Build and install the gRPC C core libraries

$ cd grpc
$ git pull --recurse-submodules && git submodule update --init --recursive
$ make
$ sudo make install

Note: you may encounter a warning about the Protobuf compiler protoc 3.0.0+ not being installed. The following might help, and will be useful later on when we need to compile the protoc-gen-php tool.

$ cd grpc/third_party/protobuf
$ sudo make install   # 'make' should have been run by core grpc

Install the gRPC PHP extension

$ sudo pecl install grpc-beta

OR

$ cd grpc/src/php/ext/grpc
$ phpize
$ ./configure
$ make
$ sudo make install

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

extension=grpc.so

Install Composer

$ cd grpc/src/php
$ curl -sS https://getcomposer.org/installer | php
$ sudo mv composer.phar /usr/local/bin/composer
$ composer install

Unit Tests

Run unit tests

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

Generated Code Tests

Install protoc-gen-php

$ cd grpc/src/php/vendor/datto/protobuf-php
$ gem install rake ronn
$ rake pear:package version=1.0
$ sudo pear install Protobuf-1.0.tgz

Generate client stub code

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

Run a local server serving the math services

• Please see Node on how to run an example server

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

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/src/node
$ nodejs examples/math_server.js

Make sure you have run composer install to generate the vendor/autoload.php file

$ 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/src/node
$ nodejs examples/math_server.js

Make sure you have run composer install to generate the vendor/autoload.php file

$ 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
