java is a very powerful programming tool, and its extension library is also very useful. This tutorial mainly describes how to use php to call powerful JAVA class libraries (classes). To facilitate your learning, this tutorial will include JAVA installation and some basic examples.

Installation under windows

Step 1: Install JDK, this is very easy, you only need to press Enter all the way to install it. Then do the following steps.
Add: "PATH=%PATH%;C:jdk1.2.2bin" to the AUTOEXEC.BAT file under Win9x
Add ";C:jdk1.2.2bin" to the environment variable under NT.

This step is very important so that PHP can correctly find the JAVA class that needs to be called.

Step 2: Modify your PHP.INI file.
[java]
extension=php_java.dll
java.library.path=c:webphp4extensions
java.class.path="c:webphp4extensionsjdk1.2.2php_java.jar;c:myclasses"

Add extension in PHP.INI =php_java.dll
And in [java], set java.class.path so that it points to php_java.jar. If you use a new JAVA class, you should also save this path. In this example, We use the c:myclasses directory.

Step 3: Test the environment and create the following PHP file:

$system = new Java("java.lang.System");
PRint "Java version=".$system->getProperty ("java.version")."
n";
print "Java vendor=".$system->getProperty("java.vendor")."

nn";
print "OS ". $system->getProperty("os.name")." ". arch")."
n";

$formatter = new Java("java.text.SimpleDateFormat","EEEE,
MMMM dd, yyyy 'at' h:mm:ss a zzzz");
print $formatter->format(new Java("java.util.Date"))."n";

?>

If you installed it correctly, you will see the following information:

Java version =1.2.2
Java vendor=Sun Microsystems Inc.
OS=Windows 95 4.10 on x86
