Question

I am trying to call an associative array and I am confused why this would not work.

if I print_r($test); it shows the following:

Array(
[e7a36fadf2410205f0768da1b61156d9] => Array(
        [rowid] => e7a36fadf2410205f0768da1b61156d9
        [id] => 3
        [qty] => 1
        [price] => 20
        [name] => test
        [options] => Array(
                [permName] => large
            )
        [subtotal] => 20
    )
)

but if I do $test[0]["rowid"]; it gives the following error Message: Undefined offset: 0

I am still a php newbie but from what I have learned about arrays so far this should work. Any ideas?

Thanks

Answer 1

Your array is associative so $test[0] doesn’t exist.

$test['e7a36fadf2410205f0768da1b61156d9']['rowid']

If you want to get the first element without referencing the key you can use reset($test)

$first_element = reset($test);
$first_element['row_id'];

The two examples are functionality identical.
