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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))

More CGI Programs and Facilities

Learn how to upload and download files, how to email from the server, how to recognise which browser your client is using, and how to return a page that automatically moves on to a second response page a few seconds later.

2321Uploading and Downloading files - changing names (Perl and PHP)
When you are uploading a file to a server via http (in Perl or PHP), where is the file saved, and what is it called? And when you download a file, where is it saved on your local disc, and what name is it given? These are not unusual questions, but it can be hard to find the answer, as I was reminded ...
1187Updating a page strictly every minute (PHP, Perl)
For the Clock exercise that I mentioned in my last entry, I need to update the page once a minute. Exactly once a minute. At the start of the minute. I'm using client pull, where the browser asks for the next page - so my basic request is: <meta http-equiv="refresh" content="60; url=/clock/now.php"> but ...
