remove "holes" from array

[Anon]

Hi,

Is there a way of removing "holes" from an array. These "holes" are created when I unset an array element.

e.g.

$stack = array ("orange", "apple", "raspberry");

if I remove (unset($stack[1]), i am left with a hole in $stack.

$stack has now element indexes 0 and 2.

Note: if i sort this array, i get the indexes re-generated, and the "holes" removed, but it works only for more than 2 elements.

$stack = array ("orange", "apple") ;

if I unset($stack[0]) and sort $stack, i don't get the element "apple" at position 0.

The reason i need "holes" to be removed is for the For loop, where the counter increments every time and when the counter reaches the element "hole", i want to skip the "hole".

Any solutions on removing "holes" from array and regenerate the indexes properly, even in a 2 element array ?

Thank you.
Brij.

Why not just stop using the for loop and use while(list($iKey,$sVal) = each($aArray))?

The 'while' loop works fine with my script.

But still wondering if there is a way to remove 'holes' from an array, just to keep all key indexes in the correct order without any missing nos.

Just rebluiding the array should do that, but if you don't absolutely need them, then don't.
