Yes the items are grabed by their index.
I'm using those arrays to manipulate 3D geometric shapes,
(either vrml/x3d, OpenGL, POV and other ones**)

If you unset an array that isn't associative, will that mean there will
be a gap in the numbers? Or will PHP realize "OK I need to change the
numbers indexing the other elements"?

Well, if you knew (for instance) that $A[2] should be removed then you
could do something like:
$value)
{
if ($key < 2)
{ $B[$key] = $value; }
elseif ($key > 2)
{ $B[($key - 1)] = $value; }
}
?>
Modify the above code as needed...

No this function does not exactly what I want.
unset() makes empty hole with $A[2] = Null
I would like to have this result :
Array
(
[0] => a
[1] => b
[2] => d
[3] => e
[4] => f
)
and not this one :
Array
(
[0] => a
[1] => b
[3] => d
[4] => e

is it possible to remove an element of an indexed array such as this exemple
$A = array('a', 'b', 'c', 'd', 'e', 'f');
in a way that we can optain this result :
$A = array('a', 'b', 'd', 'e', 'f');
something like that perhaps ?
array_remove($A, 2);
If such a function does not exis
