| 2981 | How to set up short and meaningfull alternative URLs
Wouldn't it be nice is URLs were shorter? Well - there are ways of making them shorter these days and you'll find them on networking sites like Twitter ... http://bit.ly/d7t8ID or http://bbc.in/XTQ8V . But where such URLs gain in brevity, they loose in comprehensibility.
But it's very easy to provide ... | 2010-10-02

| 2478 | How did I do THAT?
I had great fun putting together yesterday's blog about My train journey from Melksham, with a whole lot of images in the text rather than real words.
For my first tests, the images sat on the line like this: which starts to look really ugly once you 've added more that a couple of pictures - so I ... | 2009-10-26

| 2025 | Injection Attack if register_globals in on - PHP
You may have heard me talk about "injection attacks" and that having register_globals set to on in PHP makes you liable to be caught by them. Well - that's a little bit dramatic as you can write perfectly safe PHP scripts with the setting on if you're careful. Here's an example of a script which is ... | 2009-02-04

| 1983 | Keeping PHP code in database and running it
The software for these articles lets me enter HTML and keeps it in a database. If I want to add PHP, that gave me a problem as the data (HTML) was simply read from the database and passed to my client's browser without being parsed for <?php to ?> sections. But problem solved in two different ... | 2009-01-11

| 1958 | PHP - Parse error: syntax error, unexpected $end ...
Have you ever had an irritating PHP message that says "parse error" or "syntax" error and little else - and points to $end / the last line of your PHP file which is (a) perfectly ok and (b) probably HTML anyway? Something like this:
Dorothy:~ grahamellis$ php floppy
Parse error: syntax error, ... | 2008-12-23

| 1010 | Dates, times, clickable diarys in PHP
It's that quiet week between Christmas and the New Year that's an excellent chance to catch up - a little - on some of the things that are important but have been abandoned in the mad rush of urgent things these last 9 months. Like writing a booking system and like - I hope - spending long overdue ... | 2008-12-21

| 1684 | Two PHP include files to make easy web site indexing and navigation
My 'work' in campaigning for an appropriate train service on our local "TransWilts" line started three years ago now (!) with the Save the Train web site ... and grew to include the First Great Western coffeeshop (forum) covering all services in a wedge to the West of London, once we realised that we're ... | 2008-06-23

| 1667 | Checking server performance for PHP generated pages
I had a couple of reports recently about web pages from our site being a little slow to load, and my independent spy tells me that they're not bad, but not the world's fastest either. And a little thought lead me to conclude that could be because of the various PHP scripting elements included at the ... | 2008-06-07

| 1649 | Easy conversion - image formats, currencies and distances
If you're converting between distances (inches, feet, metres, centimetres, metres, furlongs or perches), between currecies (dollars, euros, pounds, roubles, lira) or between graphic file formats (.jpg, .png, .gif, .xbm, .tiff), chances are you'll have any one of a large number of different inputs to ... | 2008-05-21

| 1270 | PHP Standalone - keyboard to screen
PHP is a web language. Yes. And No. You can use it "standalone" too, and we often do so; to develop a whole lot of functions for web use in PHP, then duplicates in some other language, would be frankly silly after all.
And so it is that during the current course, I've been running rather more demos ... | 2007-07-19

| 917 | Syntax checking in PHP
If you want to check the syntax of your PHP page without actually running it, the -l option (that's lower case letter L) to PHP at the command line will do that for you:
wellho@lightning:~/public_html$ php -l index.php
No syntax errors detected in index.html
wellho@lightning:~/public_html$
