scandir creates numerically indexed arrays. Merging these arrays will 
create a larger numerically indexed array, eg if you merge two arrays 
with keys [0] through [9], you end up with a single array with keys [0] 
through [19].

eg if the first dir generated:

$arr1

[0] "."
[1] ".."
[2] "foo.bar"
[3] "really fubar"

and the second dir generated

$arr2

[0] "."
[1] ".."
[2] "bah bah.blacksheep"
[3] "fufu.fubar"

then: array_merge ( $arr1, $arr2 );

will generate:

[0] "."
[1] ".."
[2] "foo.bar"
[3] "really fubar"
[4] "."
[5] ".."
[6] "bah bah.blacksheep"
[7] "fufu.fubar"

How you then tell which file is where, that's your headache at this point.
