PHP monitor server log
Occasionally you'll be working on a webserver and not have SSH access to it. Below is a simple script I've written that reads a server log (in this case the error log) and outputs a portion of it to a webpage.

PHP:
$no_lines = 25;
$filename = $_SERVER['DOCUMENT_ROOT']."/../logs/error.log";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);
$contents [...]
Everyone hates spam, I hate it even more than most people. If you put an email address on a website, as a mailto hyperlink, then it's likely that spam bots will find this address and start sending annoying emails.
One way to get around this is to use a clever technique which I discovered over at [...]
I'm not a fan of applications that use sounds effects, one of the first things I do when configuring a new PC is to set the Windows Sound scheme to 'No Sounds'. IE7 has the hugely annoying feature where a click sound is made when you click a link with the middle mouse button (this [...]
In PHP you can provide file downloads by using a PHP page to “pass through” the file. Of course you could just link to the actual file, however this technique means your file can kept outside of your website root. Another advantage is you can integrate this system into a PHP based user/password system easily.

The other day I was programming in PHP and needed to get the first index in an associative array. There doesn’t appear to be a built in function to deal with this so I wrote my own.

PHP:
function getArrayFirstIndex($arr)
{
foreach ($arr as $key => $value)
return $key;
}
Here's a bit of code you can test it on:

Recently I’ve been making an effort to improve my JavaScript skills, I’m not a JavaScript-Jedi yet but I have been picking up a few, tips, tricks and techniques.
One thing that I find extremely useful is using an init function to call other functions when the page has loaded. I have been using the nifty function [...]

The XOR swap lets you swap the value of integer variables without using a temporary variable, it's also slightly faster.

PHP:
$x ^= $y;
$y ^= $x;
$x ^= $y;
I can't actually think of a good reason Why you'd want to use this in PHP since memory isn't normally a big issue, however it might be good [...]
I wrote last week about how I’m trying to improve my JavaScript skills. As a small exercise I have written this function for unobtrusively selecting/deselecting checkboxes in a form.

JAVASCRIPT:
function selectAll(box)
{
// get the elements name
var id = box.id;
var name = /^([a-z]+)(_select_all)$/i.exec(id);
name = name[1];
re = new RegExp('^'+name+'_[0-9]+$');
// get the elements stauts
var state = box.checked;
// get the [...]
I started work in web development in 2004 at this point in time JavaScript was hugely unpopular in terms of web trends, this is probably because it was mostly used for annoying pop-ups, animations and whole list of other horrendous Internet crimes. I can recall having a King Herod style culling of all JavaScript from [...]
