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.
What language is this written in?

It's been a long day ... I'm not sure whether to write about my drive back from Gatwick Airport this morning through the beautiful National Trust Woods at Holmwood, Abinger Hammer with its curious clock that hangs over the road, the Hog's Back where I stopped for a bacon buttie ... then on past Stonehenge and over Salisbury Plain.

No - you KNOW the beauty of this country already. I'll write about a piece of coding that I've just completed. Can you work our the language??

if (\$dirin == "$page{dir}" and \$parts[0] == "$page{key}.html") {
for (\$k=1; \$k<count(\$parts); \$k++) {
\$state = implode(" ",explode("-",\$parts[0]));
\$state = preg_replace('/\\.html/','',\$state);
\$forumlinks .= "<a href='/resources/\$parts[\$k].html'>Link to technical articles</a><br>";
break; # first only
}
}

Yes, we'll teach you all the subjects involved.

Answer tomorrow

.... Oops .... it's the day AFTER tomorrow ... I'll answer in a comment so that other folks can "play" the question without having the answer thrust in their face first ...

Graham:Answer ....

This code is written in PHP embedded in a Perl HERE document. I had better explain.

Our Opentalk Forum provides a question and answer "stage" which past trainees and others can use to resolove issues that - although they look obvious - aren't easy to get resolved.

Answers build up on Opentalk, and we want to archive them and sort them so that they're useful for other people later on. We do this through a Perl script which runs as a regular job (crontab) and generates a page for each thread, each with its own appropriate URL. It's a part of that Perl script that I quoted on "The Horse's Mouth".

As the archive has grown, it's been desirable to have each of the archive pages placed into a category ... so that the user of the archive can look around for other similar questions and other resources too. So ... that archive pages aren't flat, but rather they're PHP ... thus the need to have a Perl program that generates a PHP script, and that's part of what you saw quoted.

So - in my example code:

\$ is a PHP variable that's used when the page is viewed
but
$ (without a \) is a Perl variable that's used when the crontab job is run.

And, no, this isn't easy code to debug!
