There are two possible ways to bridge PHP and Java: you can
either integrate PHP into a Java Servlet environment, which
is the more stable and efficient solution, or integrate Java
support into PHP. The former is provided by a SAPI module
that interfaces with the Servlet server, the latter by this
Java extension.
The Java extension provides a simple and effective means for
creating and invoking methods on Java objects from PHP. The
JVM is created using JNI, and everything runs in-process.

Example Code:

getProperty('java.version') . ''; echo 'Java vendor=' .
$system->getProperty('java.vendor') . ''; echo 'OS=' .
$system->getProperty('os.name') . ' ' .
$system->getProperty('os.version') . ' on ' .
$system->getProperty('os.arch') . ' '; // java.util.Date
example $formatter = new Java('java.text.SimpleDateFormat',
"EEEE, MMMM dd, yyyy 'at' h:mm:ss a zzzz"); echo
$formatter->format(new Java('java.util.Date')); ?>

The behaviour of these functions is affected by settings in
php.ini.
