1. if $categoriesIN comes from a POST, use $_POST['categoriesIN'] instead.
better yet use the filter extension (part of the core) to retrieve the input.

2. validate & santize your input (the reason to use the filter extension)

3. WHY do you want to extract the values and assign them to vars?
since you don't know the number of entries there is no point in creating
a stack of variables of which you have no idea what they are even called
or how many there are. instead loop the array or use an index into the
array to find the data your looking for. you don't have to create a
specific variable to use a piece of data the given element of an array
is just as valid.

4. there is the extract() function ... use at your own risk.

5. do something like this:

foreach ($array as $key => $val)
        $$key = $val;

.. again use at your own risk.
