PHP获取数据或与正在运行的Java进程交互。 （我认为不同于PHP / Java桥）

Question

I have an apache2 webserver with php installed and working. I am wondering if there is any way I can get a PHP script to access a Java program that is constantly running, mostly to just get information that the process keeps track of. The Java program is not a webapp or running within the apache server. It is a separate program.

Ive been looking into PHP/Java Bridge systems, and all they seem to do is let you run Java programs from PHP and vice-a-versa, which is not what I need. I can think of a way to do this via a web service and SOAP running on localhost, but if there is a way to avoid this and I can gain direct access to the Java program, I could get my webapp to run much faster.

The Java app that I am trying to "talk to" is a program that I wrote so I have access to the source code to make the necessary changes if something within the Java program needs to be set up.

Thanks in advance, I've been looking all over for something like this.

PHP/Java Bridges let you call a running Java program from PHP.

Read: http://en.wikipedia.org/wiki/PHP/Java_Bridge

Read: http://php-java-bridge.sourceforge.net/pjb/desktop-apps.php

The bridges actually use local socket communication, from the faq:

<?php
    include_once("Java.inc");

$i1 = new Java("your.class", "1");
$i2 = new Java("your.class", "2");
$i3 = $i1->add($i2);
echo $i3->toString() . "
";
?>

See Java.inc. And edit your java code to contain the following line:

static final php.java.bridge.JavaBridgeRunner runner = php.java.bridge.JavaBridgeRunner.getInstance("9267");
