[Attachment #2 (text/plain)]

I'd also like to add to that:

$array = array();
$array[] = 'text';
$array[2] = 123;
$array[] = 'hello';

Would output:

$array(
0 => 'text',
2 => 123,
3 => 'hello',
);

Note the missing index 1, as php makes a numerical index that is one greater than the \
highest already in use. As the index 2 was explicitly created, php made the next one \
at 3.

Thanks,
Ash

Mike,

$results[] will automatically push a value unto the end of an array.

So doing this...
------
$magic = array();
$magic[] = 'a';
$magic[] = 'b';
$magic[] = 'c';
-----

is exactly this same as doing this...
------
$normal = array();
$normal[0] = 'a';
$normal[1] = 'b';
$normal[2] = 'c';
-----

And yes, in your example "$results[]" would be equivalent to "$results[$j]"
