PHP調用python，有很多種方式，查閱了下，大致有以下方式：

system、exec、shell_exec、passthrupopen、proc_opensocketppythonPHPRPCpip(python in php)XMLRPC、jsonrpc

當然，還有ice這種通信組件，今天配置了下ice、然后運行了簡單的php和python通信、python和python通信的示例程序。

下載和安裝參見http://www.zeroc.com/download.html的Packages for Ubuntu 13.04 (Raring Ringtail) and 14.04 (Trusty Tahr)和Install instructions for Ubuntu 13.04 (Raring Ringtail)兩部分，安裝過程只碰到一個問題：E: Unable to locate package db5.3-utils，后來發現是程序包名錯了，應該是db5.3-util

用python寫服務端和客戶端程序，通過ice進行通信

——————————————————————————

1、Writing a Slice Definition:hello.ice

module Demo {    interface Printer {        void printString(string s);    };};

2、Compiling a Slice Definition for Python

slice2py hello.ice

3、Writing a Server in Python:server.py

import sys, traceback, Iceimport Democlass PrinterI(Demo.Printer):    def printString(self, s, current=None):        print sstatus = 0ic = Nonetry:    ic = Ice.initialize(sys.argv)    adapter = ic.createObjectAdapterWithEndpoints("SimplePrinterAdapter", "default -p 10000")    object = PrinterI()    adapter.add(object, ic.stringToIdentity("SimplePrinter"))    adapter.activate()    ic.waitForShutdown()except:    traceback.print_exc()    status = 1if ic:    # Clean up    try:        ic.destroy()    except:        traceback.print_exc()        status = 1sys.exit(status)

4、Writing a Client in Python:client.py

import sys, traceback, Iceimport Demostatus = 0ic = Nonetry:    ic = Ice.initialize(sys.argv)    base = ic.stringToProxy("SimplePrinter:default -p 10000")    printer = Demo.PrinterPrx.checkedCast(base)    if not printer:        raise RuntimeError("Invalid proxy")    printer.printString("python client say hello!")except:    traceback.print_exc()    status = 1if ic:    # Clean up    try:        ic.destroy()    except:        traceback.print_exc()        status = 1sys.exit(status)

5、運行server端

python server.py

6、運行client端

python client.py

7、服務端運行結果如下圖：服務端接收到了客戶端消息

用上邊的hello.ice、server.py

用php寫客戶端程序，通過ice進行通信

————————————————————————————

1、Compiling a Slice Definition for PHP

slice2php hello.ice

2、Writing a Client in PHP:client.php

<?phprequire 'Ice.php';require 'hello.php';$ic = null;try{    $ic = Ice_initialize();    $base = $ic->stringToProxy("SimplePrinter:default -p 10000");    $printer = Demo_PrinterPrxHelper::checkedCast($base);    if(!$printer)        throw new RuntimeException("Invalid proxy");    $printer->printString("php client say hello!");}catch(Exception $ex){    echo $ex;}if($ic){    // Clean up    try    {        $ic->destroy();    }    catch(Exception $ex)    {        echo $ex;    }}?>

3、執行php或訪問php
