note 22111 added to function.array-splice

It may seem obvious from the above posts, but cost me a bit of braindamage to figure this out... Contrary to the equivalence noted on this page $input[$x] = $y <==> array_splice ($input, $x, 1, $y) array_splice() will not always work as expected, even provided that you have only INTEGER keys! The following code: $t=array('a','b','c','d','e'); var_dump($t); unset($t[0],$t[1],$t[3]); $t[0]='f'; var_dump($t); array_splice($t,0,1,'g'); var_dump($t); Will produce: array(5) { [0]=> string(1) "a" [1]=> string(1) "b" [2]=> string(1) "c" [3]=> string(1) "d" [4]=> string(1) "e" } array(3) { [2]=> string(1) "c" [4]=> string(1) "e" [0]=> string(1) "f" } array(3) { [0]=> string(1) "g" [1]=> string(1) "e" [2]=> string(1) "f" } Note the position of $t[0] in the second call to var_dump(). And of course, array_splice() left it intact, changing $t[2] instead. This is because it operates the _offset_, not the _index_. :) I think that "equivalence note" should be considered buggy. ;))) Best wishes.
