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.
Exchange Rates - PHP with your prices in your users currency

Would you like to tell your user what your product will cost in his local currency? What a great idea, except that exchange rates change!

The European Central Bank, though, makes a file of exchange rates betweenthe Euro and other currencies avaialble abnd publicly accessible, and you can pick this up in your PHP application - see source code example from our PHP Techniques Workshop

You can run that code here and use our include file that gives you the currency names from here

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.
