UNSET'ing multidim array elements and reseting keys

[s_shrum]

I have a script that calls code plugins that return associative arrays:

$aData[0]...
$aData[1]...
$aData[2]...
$aData[3]...
$aData[4]...
$aData[5]...
$aData[6]...
$aData[7]...

I would like to run a search on the array data and UNSET the array rows that do not meet my criteria (this part I know how to do). This means I end up with:

$aData[0]...
$aData[1]...
$aData[3]...
$aData[5]...

Once this is done, I'd like to reset the first level key names to be consecutive like this (this is where I need help; I'm hoping for a existing builtin function but so far have not been able to find one):

$aData[0]...
$aData[1]...
$aData[2]...
$aData[3]...

TIA

PS: I'll find out soon enough once this is working but does anyone know is UNSET eats up alot of time? on large arrays?

run the final array thru [man]array_values[/man]

Perfect.

Looks like there is no time lost either (granted I just ran this on a set of 250 records but the timers I set are almost the same for before and after).

Thanx
