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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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

A lion in a cage - PHP  A lion in a cage shouldn't be a danger - but release the lion from the cage and you could be at risk.An include file that's pulled in by a PHP script shouldn't be a danger if it's used only from within that PHP script, but if it has its own URL the it could be released like the lion, and it could be a danger. If you're writing a PHP script that requires or includes files, please put the included files in a directory that's NOT got its own URL .... you can do it by giving a path to the file in the include or require statements, or by using the preconfigured directory that's set up on your PHP installation.
