Deleting contents of multidimensional arrays

[rycrostud]

Here's a good one. It's giving me a real headache.

Normally, if you have an array

e.g. $array = array($val1,$val2,$val3);

you can delete the contents by doing something like:

unset ($array[2]);

would delete '$val2' from the array.

How do you delete the contents of a 2 dimensional array of this kind of construct?:

$array1 = array($array2 = array(id => $id, code => $code, price => $price, qty => $qty));

i.e. I need to delete an entire $array2 from $array1.

unset() doesn't seem to work in this case. I guess it's because I'm trying to delete an array rather than the contents of an array.

An ideas?

Hard question.

I found this:
$key_index = array_keys(array_keys($array), $target_key);
array_splice($array, $key_index[0], 1);

I'll suppose you have something like this:

$array = (ID => array (INFO));

You can try to do something like:

unset($array['2']); // you should remove the key '2' from the array.

orelse

$key_index = array_keys(array_keys($array), 2);
array_splice($array, $key_index[0], 1);


Should work as well.

P.S. i got this info in
