For 2023 - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
There is a function in PHP to do that
Once you understand the philosophy behind a programming language, you can make superb use of it. Initial learning will show you a few things and get you comfortable, but once you've also learnt a few of the things behind the language you can become a real wizard. Your educated guesses will usually be correct, and you'll be able to move on to write productive original code as you understand the nature of the beast you're using.
PHP is a language that was designed to allow embedded functionality to be provided in the form of extra tags to be interpreted server side from within an extended HTML (this is why I sometimes call it an HTML++ language). There's a huge range of these extra tags, to the extent that I have a regular saying when I'm running a PHP course
that goes along the lines "there's a function to do that"
... and some of those functions are truly remarkable.
Would you like to highlight your PHP syntax to help in debugging perhaps? There's a function to do that
is the only active line in a demo file I've just uploaded. The results presented
show one of our training scripts in a much more readable form that the usual monochrome, and without the need to buy any extra editor addins / development tools either. (written 2005-02-21, updated 2008-05-16)
