[Php-java-bridge-users] PHP interface not found

[<php...@li...>]

Dear PHP-Java bridge users,

Am trying to get Tomcat 6 to run Tiny Tiny RSS (http://tt-rss.org), which requires PHP.

Having installed and configured everything, when I visit the page, an exception is thrown, complaining that a certain PHP interface was not found:

javax.servlet.ServletException: java.lang.RuntimeException: PHP Fatal error:  Interface 'IDb' not found in .../webapps/tt-rss/classes/db.php on line 2

	php.java.servlet.PhpCGIServlet.handle(PhpCGIServlet.java:452)
	php.java.servlet.CGIServlet.doGet(CGIServlet.java:474)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:617)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

root cause:

java.lang.RuntimeException: PHP Fatal error:  Interface 'IDb' not found in .../webapps/tt-rss/classes/db.php on line 2

	php.java.servlet.fastcgi.FastCGIServlet$CGIRunner.parseBody(FastCGIServlet.java:503)
	php.java.servlet.fastcgi.FastCGIServlet$CGIRunner.doExecute(FastCGIServlet.java:402)
	php.java.servlet.fastcgi.FastCGIServlet$CGIRunner.execute(FastCGIServlet.java:410)
	php.java.servlet.CGIServlet.handle(CGIServlet.java:401)
	php.java.servlet.PhpCGIServlet.handle(PhpCGIServlet.java:427)
	php.java.servlet.CGIServlet.doGet(CGIServlet.java:474)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:617)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

The interface in question is located in a separate file, idb.php, to be found in the same directory as db.php.

The first few lines of db.php are,

<?php
class Db implements IDb {

Not having ever written any PHP myself, I'd really appreciated some help.

Thanks,

Rob
