PHP - 重复的数组值

Question

所以我有这个数组;

Array ( [0] => A [1] => B [2] => C ) 

我想做的是;

Array ( [0] => A [1] => A [2] => A [3] => B [4] => B [5] => B [6] => C [7] => C [8] => C)

重复每个值，A-A-A-B-B-B-C-C-C

我已经尝试过array_merge并给了我A-B-C-A-B-C

谢谢！

Answer 1

$orig = array('A', 'B', 'C');

$new = array();
foreach ($orig as $item) {
    $new[] = $item;
    $new[] = $item;
    $new[] = $item;
}
