Right now if you call array_push and the array parameter is not set, it gives the error

Warning: First argument to array_push() needs to be an array in FILE on line NUM

array_push should check to see if the variable is set or NULL. Only if it is NULL should it create a new array. If there is already something assigned to the var it should do nothing.

No, it should not. It's up to the user to pass an array to the function. Use is_array() to check if it's actually an array you pass or not.
