Question

The array looks something like this:

$array = array(
  array(
    'Item' => array(47, 48, 46, 42),
    'ID' => 1,
  ),
  array(
    'Item' => array(29, 37, 46, 48),
    'ID' => 2,
  ),
  array(
    'Item' => array(33, 27, 18),
    'ID' => 3,
  ),
);

What I am trying to do is to search through the [Item] arrays and if there is a match, add the [ID] to a new array.

So, if I was looking for 46 then I would get the results back of ID’s 1 and 2 in a simple array.

I’m sure this should be so simple, but I seem to have hit a complete mental block so any help would be much appreciated.

Answer 1

Try:

$ids = array();
foreach($yourArray as $v)
    if(in_array(46, $v["Item"]))
        $ids[] = $v["ID"];
