<H1>PHP/Java Bridge settings</H1>
<p>
The PHP/Java Bridge web application contains two servlets. The <code>PhpJavaServlet</code> handles requests from remote PHP scripts running in Apache/IIS or from the command line.
The second servlet <code>PhpCGIServlet</code> can handle requests from internet clients directly.
<p>
The following shows the settings of the <code>PhpJavaServlet</code> and the <code>PhpCGIServlet</code>.
</p>
<H2>PhpJavaServlet</H2>
<p>
The <code>PhpJavaServlet</code> handles requests from PHP clients.
<blockquote>
<code>
Apache/IIS/console::PHP <--> PhpJavaServlet
</code>
</blockquote>
It listens for PHP/Java Bridge protocol requests on the local interface or on all available network interfaces and invokes Java methods or procedures. The following example accesses the bridge listening on the <strong>local</strong> interface:
<blockquote>
<code>
<?php <br>
require_once("http://localhost:8080/JavaBridge/java/Java.inc");<br>
$System = java("java.lang.System");<br>
echo $System->getProperties();<br>
?>
</code>
</blockquote>

<tr VALIGN=TOP>

<th WIDTH="60%">Description</th>
</tr>
<tr>
<td>servlet_log_level</td>
<td><?php echo java_values($bridge->getlogLevel());?></td>
<td>The request log level.</td>
</tr>
</table>
</p>
<p>
<?php if (java_instanceof ($servlet, $CGIServlet)) { ?>
<H2>PhpCGIServlet</H2>
<p>
The <code>PhpCGIServlet</code> runs PHP scripts within the J2EE/Servlet engine.
</p>
<blockquote>
<code>
internet browser <--> PhpCGIServlet <--> php-cgi <--> PhpJavaServlet
</code>
</blockquote>
<p>
It starts a PHP FastCGI server, if possible and necessary. Requests for PHP scripts are delegated to the FastCGI server. If the PHP code contains Java calls, the PHP/Java Bridge protocol requests are delegated back to the current VM, to an instance of the <code>PhpJavaServlet</code>.
