The Xdebug extension is not loaded. No code coverage will be generated on Ubuntu with Xampp

I have a problem to install xdebug on my Ubuntu Server which is using xampp. I know in Stack Overflow there are several questions about this kind of problem but I did not find any solution. First this is the output of `php --version` command: ``` PHP 5.3.8 (cli) (built: Sep 19 2011 13:29:27) Copyright (c) 1997-2011 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2011 Zend Technologies with Xdebug v2.2.0, Copyright (c) 2002-2012, by Derick Rethans ``` Output of `php --ini` command: ``` Configuration File (php.ini) Path: /opt/lampp/etc Loaded Configuration File: /opt/lampp/etc/php.ini Scan for additional .ini files in: (none) Additional .ini files parsed: (none) ``` Output of `php -m` command: ``` [PHP Modules] bcmath bz2 calendar Core ctype curl date dba dom ereg exif fileinfo filter ftp gd gettext hash iconv imap intl json ldap libxml mbstring mcrypt memcache mhash ming mssql mysql mysqli mysqlnd ncurses openssl pcntl pcre PDO pdo_mysql pdo_pgsql pdo_sqlite pgsql Phar posix radius Reflection session shmop SimpleXML soap sockets SPL SQLite sqlite3 standard sybase_ct sysvsem sysvshm tokenizer wddx xdebug xml xmlreader xmlwriter xsl zip zlib [Zend Modules] xdebug ``` When I paste the output of `phpinfo()` in `http://xdebug.org/wizard.php`, the site shows the following: Tailored Installation Instructions Summary - Xdebug installed: 2.2.0 - Server API: Command Line Interface - Windows: no - Zend Server: no - PHP Version: 5.3.8 - Zend API nr: 220090626 - PHP API nr: 20090626 - Debug Build: no - Thread Safe Build: no - Configuration File Path: /opt/lampp/etc - Configuration File: /opt/lampp/etc/php.ini - Extensions directory: /opt/lampp/lib/php/extensions/no-debug-non-zts-20090626 You're already running the latest Xdebug version But here are the instructions anyway: ... ... ... (lines truncated) ... ... ... I write this on my `/opt/lampp/etc/php.ini` at the bottom: ``` [xdebug] zend_extension = /opt/lampp/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so xdebug.profiler_output_dir = "/tmp/xdebug" xdebug.profiler_enable = On xdebug.remote_enable = On xdebug.remote_host = "localhost" xdebug.remote_port = 10000 xdebug.remote_handler = "dbgp" ``` Output of `phpunit --version` is as follows: ``` PHPUnit 3.6.11 by Sebastian Bergmann. ``` Now my actual problem arises: When I use the following command it shows that xdebug is not installed: ``` phpunit --coverage-html ~/build/logs/coverage ``` This command's output is as follows: ``` The Xdebug extension is not loaded. No code coverage will be generated. ```
