some clarification:
in the test script, Daniel declared $arr as:
$arr = array('exists' => 'foo');
so when he tests
$arr['exists']['non_existent']
PHP will see that $arr['exists'] is a string, and it will convert the
'non_existent' index to int(0) and that will return the same
as $arr['exists'][0]: 'f'
If he would have defined $arr['exists'] as an array, then the code would work as
he expected, empty would returned true for $arr['exists']['non_existent']
The bit I am missing here is the statement that $arr = array ... has NOT created
an array with an element ['exists'] ... I suspect that this is perhaps where the
code *I* am looking at is breaking down ... how SHOULD you define the array so
that it is an array? So that $family = array ( 'fam1' => 'JONES' ); is the base
for the JONES family rather than simply a string. All of this USED to be simple,
but it seems to be getting so cryptic that this is what is causing the trouble :(
