I have been trying to learn CakePHP which is a Model View Controller PHP development framework.

But in the process I'm having to learn PHP and have discovered some interesting stuff.

My first ow wow that's interesting moment was that class and function names are case-insensitive.

So when it comes to these things camelCase isn't really necessary.

You can call a function:

myfunction();

myFunction();

MYFUNCTION();

And it works.

However variable names are case sensitive so:

$myvariable;

$MyVariable;

$MYVariable;

are all different.

These small things are good to know when you start with PHP.
