You know, that ("the maximum of the integer indices is taken and the new
key will be that value plus 1") is possibly a misleading clause.

For example:

$results = array();
$results[] = 'First One';

Reading that clause, "the maximum of the integer indices is taken and
the new key will be that value plus 1", one might expect the index of
"First One" to be 1. In fact, of course, it is 0. IOW, if there is no
index yet, then it doesn't add 1, but takes the first one as 0.
