For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
PHP Independent of database - How?

Posted by admin (Graham Ellis), 22 July 2002
API designers are often in a quandry when they're called on to provide an interface to a number of competing products that each has its own feature set. On one hand, they'll wish to provide good
support for all the products to which they interface, but on the other, they'll want to provide a consistency that leads to portability. This can be achieved by supporting only a common subset of

PHP as standard includes a different API (different functions) to support each of the flavours of relational database that it can be used with, allowing users the maximum of power from each database,
but reducing portability.

Portability can be added by using a wrapper library. There is also an open source wrapper library available, called ADOdb, that's gaining great popularity at present. Many of its conventions are
similar to ADO, so it should be easier for Windows programmers to use too.
