## #2667 — Lars Torben Wilson — 2003-06-23T21:52:37+00:00

Hi out there,

Wondering what should go into the docs about this:

It seems that array appending has changed wrt negative indices. I had
just documented the new behaviour but now I'm not entirely sure whether 
I've just documented an unintentional change. Is this new behaviour what
is desired (i.e. skipping straight from some negative key to 0 when
appending with $arr[] = <expr>)? 


Thanks for any insight,


Torben


Test script:
<?php
$arr[-5] = "minus five";
$arr[] = "minus four";
var_dump($arr);
?>


Output PHP 4.2.1:
array(2) {
  [-5]=>
  string(10) "minus five"
  [-4]=>
  string(10) "minus four"
}


Output PHP 4.3.2:
array(2) {
  [-5]=>
  string(10) "minus five"
  [0]=>
  string(10) "minus four"
}
