Hi Guys/Gals, If I have an multidimensional array and it has items that have the same name in it, how do I get the values of each similar item? EG: specialservices => array( specialservice => array( serviceid => 1, servicename=> signature required, price => $4.95 ), secialservice => array( serviceid => 15, servicename => return receipt, price => $2.30 ) ) How do I get the prices for each? What would be the best way to do this? Can I utilize the serviceid to do this somehow? It is always going to be different per specialservice. TIA, Best, Karl DeSaulniers Design Drumm http://designdrumm.com

This will never work. Your last array will always overwrite your previous array. Here is how I would suggest building it: $items = array(

    1 => array(
        serviceid => 1,
        servicename=> signature required,
        price => $4.95
    ),
    15 => array(
        serviceid => 15,
        servicename => return receipt,
        price => $2.30
    )

) This will ensure that your first level indexes never overwrite themselves. But, with that change made, then do this: foreach ( $items AS $item ) { if ( array_key_exists('price', $item) ) {

    echo $item['price'];

} else {

    echo 'Item does not have a price set';
