Checking out the system work

It's really useful can see what some variable is storing while we're developing the system, for that we dispose a simple function (it's really a function, not a method) to show the content from anyone kind of variable.

dump($var);

It will print with a good visualization the content of any kind of variable which is passed as parameter.

This function break the system after print

That's right, at the end of this function there's an exit to make the system break before display HTML results, it's made to remove all visual distractions. Anyway, you can disable it passing the second parameter false.

Example:

    echo dump($var, false);
