Ever used the Explode() function, and in some parts of the returned array, are NULL values? Below is a function which will only return values which are not NULL. Depending on what you are trying to achieve, this could turn out to be useful.

Just a small snippet I discovered when I was tired writing somearrayname\[i\] I thought there was something like foreach in javascript but couldn't find any so why not make one?
For those foreach(){...} lovers.

Hope it makes your life easier.
