Hi guyz,
Soon I am goign to join a computer course for PHP & mySQL [may be] including ajax. I have found a so called good isntitute. Here i have listed couple of course, i'd appreciate feedback from you guyz guiding me the most suitable one for me.

My main motive for starting the course:
Understanding web technologies , most likely the forum technologies on which the vbulletin. phpbb, myBB works. I might start developing plugins once i have the complete and deep knowledge of the courses.

Let me know which one do u think i should go with
Note:- Click on the course's link to see the detail of it.

1. Php, mySQL, Ajax
2. Php, mySQL (E-commerce)
3. Php, mySQL, Joomla

Please check the details seriously, because the course is quite expensive. Let me know if you want me to add up something or subtract something. Please check the details of the course very carefully. At the same time they are going to do a certification after the course. So would that certificate will help for anything in career?

Replies highly appreciated,
