如何获取数组中下一个相同键的值

Question

I have an array that looks like this when printed:

Array (
    [0] => stdClass Object (
        [sku] => exp_pokemonketchup_001
        [_id] =>   539be6740478ca09233ac71e
        [__v] => 0
        [type] => 3
        [status] => 1
        [_create_date] => 2014-06-14T06:06:44.365Z
        )
    [1] => stdClass Object (
        [sku] => exp_onepiecegobble_001
        [_id] => 539be6710478ca09233ac71c
        [__v] => 0
        [type] => 3
        [status] => 1
        [_create_date] => 2014-06-14T06:06:41.110Z
    )
    [2] => stdClass Object (
        [sku] => exp_sailormoongiggle_001
        [_id] => 539be66d0478ca09233ac717
        [__v] => 0
        [type] => 3
        [status] => 1
        [_create_date] => 2014-06-14T06:06:37.633Z
    )
)

I'm trying to get the sku and corresponding value for the subsequent sku during a foreach loop. In other words, I’m looping through the array, echoing the first sku, which is exp_pokemonketchup_001.

Now I also need to echo out the next sku which is exp_onepiecegobble_001 but before the loop continues to that part of the array.

Try this:

Assuming $array is your current array of objects

$array_size = count($array); 

foreach ($array as $key=>$val) {

    // echo current sku
    echo $val->sku;     

    // If not the last object, echo next sku       
    if ($key < $array_size-1) {
        echo $array[$key+1]->sku; 
    }

}
