I designed an MS ACCESS db for my clients. After entering 40+ clients into (with a LOT of data) I got an error within MS Access. This basically gives me the feeling that it is going to be very unstable which I don't like.

I just downloaded a freeware program which coverts my MS Access file to MySQL. I would like to know if there is a tutorial that I can get which will teach me the basics of manipulating a MySQL db via PHP.

Now that I have gotten better at designing wesites, I would like to design input/display pages which will be accessed on a central computer via IE.

The problem is, I don't know where to start. I have already converted the db to MySQL and the data transferred no problem, next I guess I need to know how to manipulate data... ie. add, delete, edit records... Also, display records/information on the screen.

Any help is much appreciated.
Thanks in advance.

Here are a few tutorial links I used when I first started...

and just type "php mysql tutorial" into google and you will get a bunch of good results. Have fun!

MS-Access is recommended when you have 20 users not more than that.

You might get some help there.

That is, 20 concurrent users (accessing the database at the same time).

Another option is to look at Microsoft SQL Server. There's built in options to import directly from an Access database. Microsoft have also just brought out SQL Server 2005, which looks pretty good.
