Dubbo is a distributed service framework empowers applications with service import/export capability with high performance RPC.

This is only dubbo php clinet implementation. It's only support Hessian now.

You must start dubbo and zookeeper, register prividers first.

Requirement

If you have not installed zookeeper extension for php, then

MacOS

$ brew install php56-zookeeper

Linux

$ sudo apt-get install php-pear php5-dev make  
$ sudo pecl install zookeeper

Maybe occuring an error with "zookeeper support requires libzookeeper" when you install the zookeeper extension, you should install the libzookeeper needed, And add zookeeper.so to your php.ini

$ cd ${YOUR_ZOOKEEPER_HOME_DIR}/src/c/
$ ./configure && make && sudo make install

Windows

Not currently supported, But you can through the source code compiled to a DLL

Installation

Install the latest version with

$ composer require lornewang/idiot

Usage

<?php
use Idiot\Service;
use Idiot\Type;

$options = [
    "conn" => "127.0.0.1:2181",
    "path" => "com.alibaba.dubbo.service.user",
    "version" => "1.0.0"
];

$service = new Service($options);
$data = $service->invoke('getUserById', [951]);

Numerical parameters will get the suitable data type according to the numerical region, but this often is not accurate.Such as the remote service request is a integer type of data, if the passing 951 such argument, Client will automatically mapped to a short type, it for remote service have been a strong Type of service can lead to fatal exception, at this time we need client to use Type Class to explicitly pass the parameter value and data type (in fact this is the way we recommended, because automatic mapping is unreliable)

$service->invoke("getUserById", [Type::int(951)]);

String, we can simply pass the string can be directly, also can use the Type Class of course explicitly pass

$service->invoke("getUserByName", ["Lorne"]);

// you can also
$service->invoke("getUserByName", [Type::string("Lorne")]);

When we try to pass a Java object as a parameter, you need to define an object type

Type::object("com.alibaba.dubbo.parameter.user", [
    "age": 20,
    "sex": "male"
]);

The following an example would be a complex remote invocation, we suggest that the numeric type (or even all of the data type) at any time using Type Class wrapped the original data , it will be a good habit

$service->invoke("complex", [
    Type::int(17263),
    Type::boolean(false),
    Type::string("male"),
    Type::double(16.25),
    Type::object("java.math.BigDecimal", 2367.299)
]);

Support the data wrapping type

Type::short($value);
Type::int($value);
Type::integer($value);
Type::long($value);
Type::float($value);
Type::double($value);
Type::bool($value);
Type::boolean($value);
Type::string($value);
Type::object($class_name, $properties);
