Apparently in 4.1.X this is true... I'd been running 4.0.6
for a long time (until 4.1.2 was
released), and must have coded it in the earlier version. I
stand corrected! :-)
H'mmm, I think you
But PHP builtins will do exactly this, around 3
times faster, too. :)
Yup. This one with array_diff was the winner. Thanks
to all for your suggestions and Lars for the working
one.

As far as I know there isn't such a function, what I do to achieve this:
1. find the position of the element you want to remove
2. slice the array into 2 arrays one contains all elements before this and
one contains all elements below this,
3. use shift to remove appropriate element
4. merge both
That's neat but I just read the docs. it says unset() won't work inside a
function, even if you pass by reference!
Anyways as far as you don't use functions to do the delete it will work
fine.

No. :-)
What I've had to do is add a dummy value, unset($array[4]) and then array_pop the
dummy value off
the array to get it out of there completely. The reason: unset will only remove
$array[4]'s value,
not the key.
There are plenty of other ways I'm sure, but simply unsetting has really
$layer is my array -
$currPos = array_search($HTTP_POST_VARS[selLayer], $layer);
$arrB = array_slice($layer, $currPos);
$val = array_shift($arrB);
$arrA = array_slice($layer, 0, $currPos);
$layer = array_merge($arrA, $arrB);

No, that is not at all what it says.

Thanks for all your help, everyone, but both
suggestions (unset and array_slice) pretty much didn't
improve on my current way. I was jsut trying to find a
faster way, but unset doesn't seem to be working
properly (but I'll need to fiddle more) and the
array_slice way is just too intensive.
