For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
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

highlight_file("../../trainee/h106/a3.php4"); 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.

This is a page archived from The Horse's Mouth at http://www.wellho.net/horse/ - the diary and writings of Graham Ellis. Every attempt was made to provide current information at the time the page was written, but things do move forward in our business - new software releases, price changes, new techniques. Please check back via our main site for current courses, prices, versions, etc - any mention of a price in "The Horse's Mouth" cannot be taken as an offer to supply at that price.
