Wrap the Java program in a Web Service, and invoke it from PHP. You can even use caching in the Web Service, to optimize performance.

blocks|key|1004481|text|是一个优雅的解决方案。但在许多情况下，我发现一个快速而肮脏的解决方案非常实用:启动一个使用轻量级通信协议(没有像Web中的XML这样的重量级内容)--例如：阿帕奇+--进行通信的Java服务器。编写一个非常轻的客户机，它从命令行获取参数并将输出写入控制台。客户端可以使用Java，甚至可以使用其他语言，如C%2B%2B+(Apache支持这一点)。然后使用系统()或主管()调用客户端。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1004482|这不是我推荐给生产的解决方案，但是它对于原型化来说是很好的。快速、肮脏、灵活和极其温和的学习曲线(如果您已经在Java进程之间使用了轻量级的通信)。|1004483|entityMap|0|LINK|mutability|MUTABLE|url|http://incubator.apache.org/thrift/|1|http://us3.php.net/manual/en/function.system.php|2|http://us3.php.net/manual/en/function.exec.php^0|26|3|0|4U|4|1|4Z|4|2|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@$A|S|B|T|1|U]|$A|V|B|W|1|X]|$A|Y|B|Z|1|10]]|C|$]]|$1|D|3|E|5|6|7|11|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|12|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]|P|$5|I|J|K|C|$L|Q]]]]

Web Services is the elegant solution. But in many cases I found much practical to go for a quick-and-dirty solution: start a Java server that communicates using a lightweight communication protocol (none of the heavyweight stuff like XML from Web Services) - example: <a href="http://incubator.apache.org/thrift/" rel="nofollow noreferrer">Apache Thrift</a>. The write a very light client, that takes parameters from command line and writes the output to the console. The client can be in Java or even in other languages, like C++ (Apache Thrift supports that). Then you call the client with <a href="http://us3.php.net/manual/en/function.system.php" rel="nofollow noreferrer">system()</a> or with <a href="http://us3.php.net/manual/en/function.exec.php" rel="nofollow noreferrer">exec()</a> from PHP.

This is not a solution I would ever recommend for production, but it's great for prototyping. Quick and dirty and flexible and extremely modest learning curve (if you already use light-weight communication between your Java processes).

blocks|key|945956|text|由于您使用的是PHP4，您可能只想设置一个关闭网络上的tomcat服务器，或者只是在感兴趣的机器上设置本地服务器，并让它与servlet通信，这样您就不必编写多线程服务器并处理创建通信接口的问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|945957|如果您可以升级，此页面还有另外两个可能感兴趣的选项：http://us3.php.net/manual/en/intro.java.php|offset|length|945958|entityMap|0|LINK|mutability|MUTABLE|url|http://us3.php.net/manual/en/intro.java.php^0|0|Q|17|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

Since you are using PHP4, you may want to just set up a tomcat server that is on a closed network, or just local on the machine of interest, and have it communicate with a servlet, that way you don't have to write a multi-threaded server and deal with creating a communication interface.

If you can upgrade, this page has two other options that may of interest:

blocks|key|946072|text|Web服务就是答案。这是一个不错的引线。您的问题就是web服务出现在最前沿的原因--通常无法通信的系统之间的通信。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|946073|web服务本质上要做的是在PHP和Java系统之间发送XML。您将不得不为这两者建立一个接口，这在新兴企业可能会更加困难，但您将在稍后获得好处。无论是哪种情况，它都比在服务器上读取和写入文件要快得多。磁盘I/O是任何服务器的主要瓶颈。|946074|entityMap|0|LINK|mutability|MUTABLE|url|http://www.w3schools.com/webservices/ws_intro.asp^0|H|2|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

Web Services is the answer. Here's a nice <a href="http://www.w3schools.com/webservices/ws_intro.asp" rel="nofollow noreferrer">intro link</a>. Your problem is the very reason web services came to the forefront - communication between systems that couldn't ordinarily communicate.

What a web service is essentially going to do is send XML between the PHP and the Java systems. You're going to have to establish an interface for the two, which might be more difficult at the upstart, but you'll reap the benefits later on. In either case, it will be much faster than reading and writing files on the server. Disk I/O are the major bottlenecks on any server.

I may miss something, but if your java program output the needed values, can't you just start the java program from php using exec (<a href="http://dk.php.net/manual/en/function.exec.php" rel="nofollow noreferrer">http://dk.php.net/manual/en/function.exec.php</a>)

We're come across a problem here at my company and I'm trying to find the best solution. 

Software was recently purchased that utilizes a Java program to get the tax for a certain shipment. The site that needs this was written in PHP4. How can I communicate between the two?

It was suggested to use files to communicate but that was horribly slow since the Java program needed to be recompiled every time. So, what is the best solutions to this:

<ol>
<li> Create a mutli-threaded Java server and use PHP to send/receive the info.</li>
<li> Some other type of file-writing method</li>
<li> Something cool that I dont even know about.</li>
</ol>

Thanks in advance!

Edit: 
I understand the importance of web services but why would this be more efficient that using a mutli-threaded socket-based java server? The only thing connecting to this web services will be my PHP program, no one else. It seems like it might be overkill for my simple task. Am I mistaken? If so, why? Thanks.

我们在我的公司遇到了一个问题，我正在努力寻找最好的解决方案。最近购买的软件使用Java程序为某一批货物征税。需要这样做的站点是用PHP4编写的。我怎样才能在两者之间交流呢？有人建议使用文件进行通信，但这非常慢，因为每次都需要重新编译Java程序。那么，对此最好的解决方案是什么：创建一个多线程Java服务器，并使用PHP发送/接收信息。一些其他类型的文件写入方法一些我都不知道的很酷的东西。提前感谢！
