If you ever utter the words "It's definitely not that.", it's 100% certainly, without a shadow of doubt, exactly that.

Just a few short years ago, options for Open Source PHP ecommerce platforms were extremely limited, and often the only way to put together an ecommerce store online was to have a bespoke system built. Not any more, though - now there are plenty of options. We take a look at the top five contenders to see what each has to offer.

If PHP Were British

20 August 2011   |   Comments   |   php, development, humour, empire

When Rasmus Lerdorf first put PHP together, he - quite sensibly, despite his heritage - chose not to write it in Greenlandic or Danish. Good job too - that would have been rather unpleasant to work with. He opted instead, being in Canada, for a more local tongue. No, not French. Not Canadian English either. No, he went for that bastard dialect of the Queen's English commonly referred to as "US English".

PHP developers in Britain have been grumpy about this ever since. What was he thinking? And more importantly, how do we undo this travesty? How do we developers ensure the traditions of the British Empire continue to be upheld, even in the digital age?

A Slap in the Face


The first, but maybe the most important, of many changes that will allow PHP to achieve a more elegant feel is to remove that symbol so beloved by the US and replace it with something altogether more refined. More solid. More ... sterling.


Getting Started

    echo 'Hello World!';

How many of today's British programmers have been put off at the outset by the brazen informality of this simple yet obscenely Americanised program, colloquially referred to as "Hello World"? A more Imperial, formal introduction might encourage a greater proportion of young British talent to remain with the language and thus give the broader community a more urbane air.

    announce 'Good morrow, fellow subjects of the Crown.';


Few things are more abhorrent to the British than unnecessary abbreviations. "Text speak" is unheard of on the streets of London, as the natural ingrained British grammarian simply refuses to stoop to sending messages of the "c u soon traffic kthxbye" variety, instead proferring something altogether more elegant: "Dear Sir/Madam. I will arrive as soon as time allows, which I expect to be within the hour. I assure you the horses shall not be spared. Yours respectfully." (slower to type, yes, but we do not like to be rushed).

PHP, on the other hand, is full to bursting with abbreviations and acronyms which are entirely unnecessary:


The following changes should improve things:


Edit: I have corrected the expansion of "preg_match" - thanks to those who pointed it out.


if ($condition) {
    // Code here
} else {
    // Code here

Shakespeare would be ashamed to see his native tongue twisted into this monstrosity. Brevity is to be applauded in the right context - in some dark corner, where it shall be seldom seen - but not here. The if ... else block is the most used conditional code in all of PHP, so it must be made as inoffensive as possible. There are many options for its replacement, but this may be the strongest:

perchance (£condition) {
    // Code here
} otherwise {
    // Code here

The same naturally applies to the Americanised switch ... case construct, which one can only describe as clunky and unpleasant:

switch ($variable) {
    case $option1:
        //Code here
    case $option2:
        //Code here
        //Code here

Words such as "switch", "break" and "default" are hard on the reader and lack context. The Right Honourable biggerthancheeses was kind enough to contribute a more gentrified suggestion (and has some interesting ideas, particularly around replacement of "include()" with something like "i_might_be_partial_to()", demonstrating a natural talent for the Imperialisation of programming languages):

what_about (£variable) {
    perhaps £possibility:
        //Code here
    perhaps £other_possibility:
        //Code here
        //Code here



Words fail me at this point. How is any self-respecting gentleman expected to make head or tail of these "words". It beggars belief that anyone could allow such distortions of words to be entered into a programming language. They, along with the cornucopia of similar errors, should be reverted to their proper forms immediately:



try {
    // Code here
} catch (Exception $e) {
    // Handle exception

The try ... catch block is an excellent example of PHP's lack of manners. Far too direct to be allowed in the new PHP. Additionally, the word "die" is so very depressing. This new block, although more verbose, is vastly more polite and upbeat:

would_you_mind {
    // Code here
} actually_i_do_mind (Exception £e) {
    // Politely move on


Perhaps nothing is as important and ingrained in the British psyche as the notion of class and, while there are few opportunities for change within this part of PHP, the changes that there are to be made here are important.

class Republic {
    public $a;
    private $b;
    protected $c;
$example = new Republic();

To begin with, the current system has no place for class hierarchy and this is unacceptable. So we shall begin by giving classes specific levels - upper, middle, working - and no class can access the methods of one of a higher level without the explicit permission of the higher order class (of course, though it might then have access, it would not be a true member of the higher order and could not itself grant higher order access to other lower order classes). "Public" and "Private", in the British class system, are often synonymous (see, for example, school system nomenclature), so these must be adjusted, as should the "Protected" property visibility. The word "new", while passable, has a much more appropriate replacement in matters of class.

upper_class Empire {
    state £a;
    private £b;
    hereditary £c;
£example = nouveau Empire();

The Sun Never Sets ...

It is hoped that these few simple changes will improve the reputation and status of PHP among other languages. No longer will it be the poor American cousin - instead it can take its rightful place as the - British - King of the scripting languages.


Many thanks to Mark and Pat, former colleagues, who helped start this resurrection of the British Empire in the pub on Friday.

Adding and removing variables to and from URLs using PHP can be a relatively simple process admittedly, but I have a couple of functions I use often to make the process even less time-consuming.

Add Querystring Variable

A PHP function that will add the querystring variable $key with a value $value to $url. If $key is already specified within $url, it will replace it.

function add_querystring_var($url, $key, $value) {
    $url = preg_replace('/(.*)(?|&)' . $key . '=[^&]+?(&)(.*)/i', '$1$2$4', $url . '&');
    $url = substr($url, 0, -1);
    if (strpos($url, '?') === false) {
        return ($url . '?' . $key . '=' . $value);
    } else {
        return ($url . '&' . $key . '=' . $value);

Remove Querystring Variable

A PHP function that will remove the variable $key and its value from the given $url.

function remove_querystring_var($url, $key) {
    $url = preg_replace('/(.*)(?|&)' . $key . '=[^&]+?(&)(.*)/i', '$1$2$4', $url . '&');
    $url = substr($url, 0, -1);
    return ($url);

Ternary conditionals (using the "ternary operator", sometimes known as the "trinary operator") are a part of PHP that many simply steer clear of, despite their usefulness. They can save a great deal of time when writing code and can make for much easier code to read and edit later on. They look strange to many people though, which might explain why they are not as widely used as they could be.

Consider a normal conditional statement, like the following. It begins by evaluating a condition. If that condition is true, it follows one path. Sometimes, an alternate path is specified if the condition is not true (the 'else' section). Sometimes, you can have a list of several possible conditions in a row (using 'if ... elseif ... else' or 'switch ... case').

if (condition) {
    variable = value-if-true;
} else {
    variable = value-if-false;

However, a simple situation like the above is a perfect candidate to convert to a ternary conditional. You have one condition, and if it is true, the variable is given a certain value - if false, a different value. A ternary conditional can accomplish the same thing, concatenating it into one simple line of code.

variable = (condition) ? value-if-true : value-if-false;

Ternary conditionals take the above form. You do not necessarily need to have a "variable = " section (as you will see later on), but usually that is what this is used for. The above does exactly the same thing as the 'if ... else' statement earlier. If the condition evaluates to true, the variable will be assigned the value in the "value-if-true" section, otherwise it will receive the "value-if-false" value.

In practice, you could use the ternary conditional to, for example, greet a user depending on whether it is currently morning or afternoon. Using traditional code ('if ... else'), you might write something like this:

if (date("G") < 12) {
    echo 'Good morning';
} else {
    echo 'Good afternoon';

The same statement, using a ternary conditional, would look like this:

echo (date("G") < 12) ? 'Good morning' : 'Good afternoon';

Note that in this example, we've used "echo", rather than assigning a value to a variable. The above is exactly the same as this, which does make use of a variable:

$greeting = (date("G") < 12) ? 'Good morning' : 'Good afternoon';
echo $greeting;

Another situation in which I often use ternary conditionals is when displaying rows of data. It can often be much easier for a user to see what is going in if the rows alternate background colour, and the following code can be useful for that:

$i = 1;
echo '<table>';
while ($data = mysql_fetch_array($result)) {
    echo '    <tr>';
    echo '        <td bgcolor="';
    echo (($i % 2) == 0) ? '#eee' : '#ddd' ;
    echo '">';
    echo $data['field'];
    echo '        </td>';
    echo '    </tr>';
echo '</table>';

The above code will cycle through a result set, displaying each item in a new row. The background colour of the row will alternate between shades of grey, controlled by the ternary conditional on the bold line.

Ternary conditionals make for tidier code. Use them - if not for yourself, then for whoever is going to end up editing your scripts!
