做一个 demo 感受一下整个过程，demo是简单的计算器功能。

1 目录结构

|----genphp thrift -r --gen php:server ComputeThrift.thrift 
|----lib  Thrift  的 lib文件夹
|----ComputeThrift.thrift 接口thrift文件
|----ComputeHandler.php 服务器handler定义文件
|----ComputeServer.php 服务器server代码，用于处理client请求
|----ComputeClient.php 客户端client代码
 

2 创建thrift文件

	namespace php ComputeThrift
	
	service ComputeService {
	 i64 plus(1:i64 operator1, 2:i64 operator2)
	 i64 minus(1:i64 operator1, 2:i64 operator2)
	 i64 multiply(1:i64 operator1, 2:i64 operator2)
	 i64 divide(1:i64 operator1, 2:i64 operator2)
	}
 

3 生成php server文件

	thrift -r --gen php:server ComputeThrift.thrift 
 

重命名为genphp

4 ComputeHandler.php代码

<?php
namespace thrift;
error_reporting(E_ALL);
require_once __DIR__.'/lib/php/lib/Thrift/ClassLoader/ThriftClassLoader.php';
use Thrift\ClassLoader\ThriftClassLoader;
$gendir = realpath(dirname(__FILE__)).'/genphp';
$loader = new ThriftClassLoader();
$loader->registerNamespace('Thrift', __DIR__.'/lib/php/lib');
$loader->registerDefinition('ComputeThrift', $gendir);
$loader->register();
if (php_sapi_name() == 'cli') {
 ini_set('display_errors',"stderr");
}
class ComputeHandler implements \ComputeThrift\ComputeServiceIf
{
 public function plus($op1, $op2){
 return $op1 + $op2;
 }
 public function minus($op1, $op2) {
 return $op1 - $op2;
 }
 public function multiply($op1, $op2){
 return $op1 * $op2;
 }
 public function divide($op1, $op2){
 return $op1 / $op2;
 }
}
 

5 ComputeServer.php代码

<?php
namespace ComputeThrift\php;
error_reporting(E_ALL);
require_once __DIR__.'/lib/php/lib/Thrift/ClassLoader/ThriftClassLoader.php';
require_once __DIR__.'/ComputeHandler.php';
use Thrift\ClassLoader\ThriftClassLoader;
use \thrift\ComputeHandler;
$gendir = realpath(dirname(__FILE__)).'/genphp';
$loader = new ThriftClassLoader();
$loader->registerNamespace('Thrift', __DIR__.'/lib/php/lib');
$loader->registerDefinition('ComputeThrift', $gendir);
$loader->register();
if (php_sapi_name() == 'cli') {
 ini_set('display_errors',"stderr");
}
use Thrift\ protocol \TBinaryProtocol;
use Thrift\Transport\TPhpStream;
use Thrift\Transport\TBufferedTransport;
use Thrift\ Exception \TException;
header('Content-Type','application/x-thrift');
if (php_sapi_name() == 'cli') {
 echo PHP_EOL;
}
try {
 $handler = new ComputeHandler();
 $processor = new \ComputeThrift\ComputeServiceProcessor($handler);
 $transport = new TBufferedTransport(new TPhpStream(TPhpStream::MODE_R | TPhpStream::MODE_W));
 $protocol = new TBinaryProtocol($transport, true, true);
 $transport->open();
 $processor->process($protocol,$protocol);
 $transport-> close ();
} catch(\TException $e) {
 print 'TException:'.$e-> getMessage ().PHP_EOL;
}
 

6 ComputeClient.php代码

<?php
namespace ComputeThrift\php;
error_reporting(E_ALL);
require_once __DIR__.'/lib/php/lib/Thrift/ClassLoader/ThriftClassLoader.php';
use Thrift\ClassLoader\ThriftClassLoader;
$gendir = realpath(dirname(__FILE__)).'/genphp';
$loader = new ThriftClassLoader();
$loader->registerNamespace('Thrift', __DIR__.'/lib/php/lib');
$loader->registerDefinition('ComputeThrift', $gendir);
$loader->register();
use Thrift\Protocol\TBinaryProtocol;
use Thrift\Transport\T socket ;
use Thrift\Transport\THttpClient;
use Thrift\Transport\TBufferedTransport;
use Thrift\Exception\TException;
try {
 if (array_search('--http', $argv)) {
 $socket = new THttpClient(' localhost ',8080,'/ComputeServer.php');
 } else {
 $socket = new TSocket('localhost',9090);
 }
 $transport = new TBufferedTransport($socket, 1024, 1024);
 $protocol = new TBinaryProtocol($transport);
 $client = new \ComputeThrift\ComputeServiceClient($protocol);
 $transport->open();
 $op1 = 1;
 $op2 = 2;
 $plus = $client->plus($op1, $op2);
 echo '1 + 2 = '.$plus. "\n";
 $minus = $client->minus($op1, $op2);
 echo '1 - 2 = '.$minus. "\n";
 $ multiply  = $client->multiply($op1, $op2);
 echo '1 * 2 = '.$multiply. "\n";
 $divide = $client->divide($op1, $op2);
 echo '1 / 2 = '.$divide. "\n";
 $transport->close();
} catch (\Exception $e) {
 print 'TException:'.$e->getMessage().PHP_EOL;
}
 

7 运行

php -S localhost:8080 #启动server

server

php Client.php –http #运行client，就会打印出四次算术运算的结果

client

注：这里只是在client.php里定义socket的host和port，然后转发Server.php文件执行，最终是需要server.php中定义监听端口，这样才是完整的，这里只做测试。
