Practising PHP ... the easy way

HTML and JavaScript are so easy to practise and experiment with because they are client side languages. All you need is a text editor and a web browser. Whereas PHP is a server-side language, meaning you need a server on which to host the code. Increasingly, however, it has become easier and easier to learn PHP without a complicated setup. MAMP  and WAMP have been around for quite a while now and are great packages for testing MySQL and PHP, but even easier to get started with is HyperEdit  (OS X). And yes, it had to happen sooner or later, there is an app on the iPad for writing and testing PHP called Kodiak PHP . There are other apps on OS X (and Windows) with the same functionality as HyperEdit, but none that I've found as easy to get started with and which cut through all the IDE fuss to be something that is quick and simple to use. Kodiak matches this ease of use, and is a dream for anyone who wants to code on the sofa in the evening. Kodiak does require some cu

Two ways to convert an array of any length into a string with "and" before final entry in PHP
