Me and my team has developed an online inventory control system for the use of our university. We used PHP, MYSQL, JavaScript and AJAX technologies to build it and it runs on APACHE server.
We have just picked the above technologies as we're familiar with them. But we need to clarify the reasons for using these particular technologies at the final viva. (I mean, when the lecturers ask why have you used PHP for this, we have to say something reasonable instead of saying that we know only that)
Hope someone will understand my situ and reply..

Thanks in advance!
PS: Some advantages of these technologies over other available language options may be ideal!
