This directory contains source code for PHP implementation of gRPC layered on shared C library.
Prerequisite:
php 5.5 or above, 7.0 or abovepeclcomposerphpunit (optional)Install PHP and PECL on Ubuntu/Debian:
For PHP5:
$ sudo apt-get install php5 php5-dev php-pear phpunit
For PHP7:
$ sudo apt-get install php7.0 php7.0-dev php-pear phpunit
Install PHP and PECL on CentOS/RHEL 7:
$ sudo rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm $ sudo rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm $ sudo yum install php56w php56w-devel php-pear phpunit gcc zlib-devel
Install PECL on Mac:
$ curl -O http://pear.php.net/go-pear.phar $ sudo php -d detect_unicode=0 go-pear.phar
Install Composer (Linux or Mac):
$ curl -sS https://getcomposer.org/installer | php $ sudo mv composer.phar /usr/local/bin/composer
Install PHPUnit (Linux or Mac):
$ wget https://phar.phpunit.de/phpunit-old.phar $ chmod +x phpunit-old.phar $ sudo mv phpunit-old.phar /usr/bin/phpunit
Install the gRPC PHP extension
sudo pecl install grpc
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.
Note: For users on CentOS/RHEL 6, unfortunately this step won't work. Please follow the instructions below to compile the extension from source.
Update php.ini
Add this line to your php.ini file, e.g. /etc/php5/cli/php.ini
extension=grpc.so
Add the gRPC PHP library as a Composer dependency
You need to add this to your project's composer.json file.
"require": {
"grpc/grpc": "v1.1.0"
}
To run tests with generated stub code from .proto files, you will also need the composer and protoc binaries. You can find out how to get these below.
Clone this repository
$ git clone -b $(curl -L https://grpc.io/release) https://github.com/grpc/grpc
Build and install the gRPC C core library
$ cd grpc $ git pull --recurse-submodules && git submodule update --init --recursive $ make $ sudo make install
Compile the gRPC PHP extension
$ cd grpc/src/php/ext/grpc $ phpize $ ./configure $ make $ sudo make install
You will need the source code to run tests
$ git clone -b $(curl -L https://grpc.io/release) https://github.com/grpc/grpc $ cd grpc $ git pull --recurse-submodules && git submodule update --init --recursive
Run unit tests
$ cd grpc/src/php $ ./bin/run_tests.sh
This section specifies the prerequisites for running the generated code tests, as well as how to run the tests themselves.
Install the runtime dependencies via composer install.
$ cd grpc/src/php $ composer install
Again if you don't have it already, you need to install the protobuf compiler protoc, version 3.1.0+ (the newer the better).
If protoc hasn't been installed, you can download the protoc binaries from the protocol buffers Github repository.
If you really must compile protoc from source, you can run the following commands, but this is risky because there is no easy way to uninstall / upgrade to a newer release.
$ cd grpc/third_party/protobuf $ ./autogen.sh && ./configure && make $ sudo make install
There are two protobuf runtime libraries to choose from. They are idenfical in terms of APIs offered.
$ sudo pecl install protobuf
Add this to your composer.json file:
"require": {
"google/protobuf": "^v3.3.0"
}
You need the gRPC PHP protoc plugin to generate the client stub classes.
It should already been compiled when you run make from the root directory of this repo. The plugin can be found in the bins/opt directory. We are planning to provide a better way to download and install the plugin in the future.
You can also just build the gRPC PHP protoc plugin by running:
$ cd grpc
$ make grpc_php_plugin
Generate client stub classes from .proto files
$ cd grpc/src/php $ ./bin/generate_proto_php.sh
Run a local server serving the math services. Please see Node for how to run an example server.
$ cd grpc $ npm install $ node src/node/test/math/math_server.js
Run the generated code tests
$ cd grpc/src/php $ ./bin/run_gen_code_test.sh
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 or /etc/php/7.0/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 $ node 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 stubs
$ ./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 line to point the includes to your installation:
include 'vendor/autoload.php';
Connect to localhost/math_client.php in your browser, or run this from command line:
$ curl localhost/math_client.php
Install nginx and php5-fpm, in addition to php5 above
$ sudo apt-get install nginx php5-fpm OR $ sudo apt-get install nginx php7.0-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 $ node 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 stubs
$ ./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 line to point the includes to your installation:
include 'vendor/autoload.php';
Connect to localhost/math_client.php in your browser, or run this from command line:
$ curl localhost/math_client.php
