Yes, I already know about security issues like SQL injection and others discussed in the forum concerning PHP and mysql and measure to improve security. The provision and resources I have right now is for PHP and Mysql and I have gone far in the app except how to display googlemap custom marker from mysql. However, about jrdc2, I can only handle simple program with it, once, it gets to complex coding, I get lost with the structure. I have not been able to see comprehensive tutorial when it comes to complex coding and program flow, i can connect to jrdc2 server, I can do CRUD operation and simple stuffs, but getting to complex coding structure, I get lost. At moment, I will be happy if I can get help converting the attached file above to PHP mysql version as stated in the question.
