合并2个数组交换索引PHP

Question

Not sure if I described it properly in the title, but I'm looking to merge 2 arrays in php, although I don't want the new array to have the first array first and then the second array at the end, instead I want it to have the first item of the first array, first item of the second array, 2nd item of the first array, etc

so essentially

Array 1
     A - 1
     A - 2
     A - 3

Array 2
     B - 1
     B - 2
     B - 3

and after merging the two, the resulting array will be

Array Merged
     A - 1
     B - 1
     A - 2
     B - 2
     A - 3
     B - 3

In that order, can anyone help me out?

Answer 1

Merge and sort them, while keeping the keys

$array1 = array(/* values here */);
$array2 = array(/* values here */);

$mergedArray = array_merge($array1, $array2);
ksort($mergedArray); // this also keeps the keys

Note:

Your arrays can't work, since you can't have 2 entries with the same keys :)

Basically $array2 = array('B' => 1, 'B' => 2, 'B' => 3); will result in the following array:

Array
(
    [B] => 3
)
