drop is a simple function to inspect one or more variables in a PHP script and halt execution of that script. When debugging, I've found it helpful to simply kill a script and expose the actual type/contents or a var.

Peruse the tests or, if present, the examples directory to see usage.

drop has two incarnations. drop() uses var_dump() and dropv() uses print_r(). The main difference is that dropv will give you the full value of each arg where drop will give you the ellipsis on long values.
