[PHP] Arrays within arrays question
I have the following loop to insert data into an array:
while ($data = pg_fetch_object($res)) {
$aProds[] = array('id' = $data-prod_id, 'quantity' =
$data-quantity);
}
But when I print this out using print_r I get the following:
Array
(
[0] = Array
(
[0] = Array
(
[id] = 289000100024
[quantity] = 1
)
[1] = Array
(
[id] = 289000100050
[quantity] = 1
)
)
)
This array has only one element in it; not what I wanted. I wanted
something like this:
Array
(
[0] = Array
(
[id] = 289000100024
[quantity] = 1
)
[1] = Array
(
[id] = 289000100050
[quantity] = 1
)
)
How can I achieve this?
Thanks!

Okay, it may be the end of a long day here, but I can't tell the difference
between the two arrays you posted!

That one element contains two elements, each and array with two elements. The other array contains two elements, each element being an array itself with two elements.

If $aProds can contain more than 1 item then what you're doing now is correct.
If $aProds will only ever contain 1 item then use:
$aProds = array('id' = $data-prod_id, 'quantity' = $data-quantity);
But then you can drop the while-loop and probably can just do:
$aProds = pg_fetch_object($res);

The problem was that I was doing this: $return[] = get_array_of_prods(); the [] was creating the extra array level ... The problem I now face is that foreach keeps crapping out if I pass it an unitialized (i.e. has no value) array.

Re: [PHP] Arrays within arrays question
I always put an if(is_array($var)) to check if an array was actually return.
