从两个阵列打印信息

Question

Trying to print infomation from array now, and dont want to use manu foreach in foreach cycles. So interesting how to output data from this array

Array
(
[aM] => Array
    (
        [0] => Array
            (
                [iId] => 0
                [iTime] => 00
            )

        [1] => Array
            (
                [iId] => 1
                [iTime] => 11
            )

        [2] => Array
            (
                [iId] => 2
                [iTime] => 22
            )
    )

[aN] => Array
    (
        [0] => Array
            (
                [sName] => a
            )

        [1] => Array
            (
                [sName] => b
            )

        [2] => Array
            (
                [sName] => v
            )
    )
)

Like this, data from first array near data from second

0 a, 1 b, 2v

? Not like here, first we output all data from first, than from second

0 1 2 a b v

?

Answer 1

You can easily do this with a MultipleIterator, which will iterate over both arrays easily:

// $array = your array from up there

$iter = new MultipleIterator;
$iter->attachIterator( new ArrayIterator( $array['aM']));
$iter->attachIterator( new ArrayIterator( $array['aN']));

foreach( $iter as $data) {
    list( $a, $b) = $data;
    echo $a['iId'] . ' ' . $b['sName'] . ',';
}

You can see from this demo that it prints (for PHP >= 5.3):

0 a,1 b,2 v,
