Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [5] => 9
    [6] => 8
    [7] => 7
    [8] => 6
)

But:
 $a = array(1=>'one',2=>'two',3=>'three',4=>'four');
 unset($a[2]);
 print_r($a);
Array
(
    [1] => one
    [3] => three
    [4] => four
)

It must be difficult to understand for the beginner, but in fact "it just works" if
you set the index.

I counted 47 array functions with "array" in the name, and about the same number with
other names (http://php.net/manual/en/function.array.php), most of them I find fairly
unusable.

/Str.
