Choosing a railway station fairly in PHP

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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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

I've been transferring the West Wilts Rail Users Group web site into a wiki this evening ... and came up with the question "How do I fairly choose which station to put on their front page".

Of course, I favour Melksham. It's far and away the one that needs all the help and support it can get from such groups, with just 2 trains a day each way for a population of over 20,000 (and compare that to an estimated 100 departures a day from Westbury - a town of half the size).

But - seriously folks - it has to be a randomly chosen station.

I don't know which is shown at the top of this article at the moment as it's fed by a PHP script that chooses at random:

<?php 

header("content-type: image/jpeg");

$opts = array("avo","boa","tro","mkm","wes","dmh","war");

$last = $opts[rand(0,6)];

$fh = fopen("wwrug_$last.jpg","r");

$blow = fread($fh,filesize("wwrug_$last.jpg"));

print $blow;

?>
