Question

I am trying to update only some values of an Array directly. Which is working perfectly. I am using the following method:

foreach( $items as &$item ) {
    if( $criteria == 'correct' ) {
      // update array
      $item['update_me'] = 'updated';
    }
}

So I now have an updated array called $items.

However, the problem I have, is when this Array is output to screen (via another foreach loop), the last row of the Array is missing.

If I print the entire array via the var_dump( $items ); method, I noticed that each row is prefixed with Array(9). Yet the last row is prefixed with &Array(9) – notice the leading ampersand. I’m sure this is significant! But I’m unsure what it means. Why is it only applied to the final row in the Array? And how do I get rid of it?

From comment:

array(6) { 
    [0]=> array(9) { 
        ["item_id"]=> string(4) "1" 
        ["item_description"]=> string(9) "blah blah" 
        ["quantity"]=> string(1) "4" 
        ["unit_cost"]=> string(4) "5.00" 
        ["subtotal"]=> string(4) "20.00" 
    } 
    [1]=> &array(9) { 
        ["item_id"]=> string(4) "2" 
        ["item_description"]=> string(9) "blah blah" 
        ["quantity"]=> string(1) "1" 
        ["unit_cost"]=> string(4) "5.99" 
        ["subtotal"]=> string(4) "5.99" 
    } 
}

i think that’s not the nicest way to do this. i’d suggest doing it this way:

foreach( array_keys($items) as $itemkey ) {
    if( $criteria == 'correct' ) {
        // update array
        $items[$itemkey]['update_me'] = 'updated';
    }
}
