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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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

i am trying to make an image based website script work, and finding it very difficult.  Error message is:

Fatal error: Call to undefined function: imagegif() in /home/www/mylogin/libraries/functions.lib.php on line185

Do you have the GD library, and the right version, loaded with your PHP? If you put up a web page that's just

<?php phpinfo(); ?>

you'll get a report telling you all about your settings. Example -running and source code

Also, from the PHP manual ...

Note: Since all GIF support was removed from the GD library in version 1.6, this function is not available if you are using that version of the GD library. Support is expected to return in a version subsequent to the rerelease of GIF support in the GD library ...

Function names in PHP are not case sensitive, by the way - you'll see this fucntion referred to as ImageGif, ImageGIF, imagegif and imageGIF ... and they're all references to exactly the same thing!
