For 2023 - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))

Using cookies and sessions to connect different URLs - PHP

One of the great beauties of cookies (and derived from that, of PHP sessions) is that they can be used across a series of pages on the same server - indeed we use cookies on this site to record our visitor's preferences for colour, font size, country and open source langauge(s) via our user preference page, and we then use those inputs to apply to all pages and styles on the site.

We're a simple session demonstration showing this in a module from our new PHP Techniques Workshop that we ran for the first time last week - the source code of the first page is here and the source of a second page is here.

Run the first page here and each time you do so you'll step through a limeric. Run the other page hereto report on the status of the first page from a different URL.

Practical uses of this? Anything from two applications which need to share data but are maintained by different teams to applications with multiple top level pages - and even captcha technology, where the session is used to link the graphics to the page. More about that latter here and try in 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.
