Should be more clear in the docs. It is only implicitely there.
Assigning to myself.

If you unset an element in the array, it does not make the whole array shift so it
starts from index zero again. That's normal behaviour.

<?php
//Two elements in an Array
$array[] = "Maria";
$array[] = "Lisa";
//just a test output
array_walk ($array, "my_print");
//and then free the first element of the array
unset ($array[0]);
function my_print ($value)
{
print $value . " ";
}
print "<br />";
//The following dump will produce:
//array(1) { [1]=> string(4) "Lisa" }
//This means that the first element has the index 1
//But it should have index 0
var_dump ($array);
?>
If you have more than two elements, and you free one of them, you can just prevent
this bug, by resorting the array with any sort function. But with only two elements,
this won't work, and if you clear the first of these, you will get the same result as
I have got, there was one element, but with the wrong index.
