Why should I care about PHP Shorthand If Notation or the Ternary Operator
Programming would be a bit useless without being able to evaluate conditions using if/end and switch statements. If/Else statements is obviously a great tool, but they aren’t optimal (or necessary) in all situations. And so I introduce you to … PHP Shorthand If Notation or the Ternary Operator.
Ternary operator takes the form “(condition) ? (true return value) : (false return value)” to shorten your if/else structures.

OK, a simple thing I know. But one that always occurs.
When using shared hosting (or even your own dedicated servers), those managing those servers do their utmost to make them secure. Among many things this usually includes turning off ‘display_errors’ in the php.ini file.
However, when you’re trying to develop things it is usefull to display errors and warnings, but if ‘display_errors’ is off, you will be scratching your head wondering what’s going on and whats going wrong!

Object-Orientated programming is not a new idea! It’s been around and available for a long time in many languages.
With each new version of PHP, new features appear, while existing features are improved. PHP’s object support has been hugley improved since it’s introduction in PHP3 (yes it has had it all this time!). And so with PHP’s object support maturing, the reasons developers might not take an object orientated approach are getting smaller. More recently PHP5′s take on objects is much more powerfull and usable than it ever has been for PHP users – but still not without it’s faults.

For those who do not know about OOP I am not even going to attempt to explain what it is! But fact you have found this article means you probably do, but incase not Wikipedia has good general background info on OOP.

If you are a professional developer (or aspiring) you will inevitably get asked to customise or even better “extend” existing wares.
If it’s a product you are familiar with great! If not I heartilly reccomend spending a little time investigating prior to accepting a job ( ultimatley if they are happy to give
access to their code, if not atleast tell you what’s been used so you cam repliocate it to play with briefly). I know this sounds like a lot of work wich ultimatley – if you
don’t accept the job – you have done for free, but it will save you masses of grief, tears and late nights if you do.
So, I have a few pointers to ‘be aware of’ while evaluating the job and to (generally) identify crappy PHP products/solutions quickly…
