如何通过特殊的charcter连接php中的两个数组元素值？

Question

我有两个阵列如下

Array
(
    [0] => 2013-07-09
    [1] => 2013-07-16
    [2] => 2013-07-23
    [3] => 2013-07-30
)

Array
(
    [0] => 2013-07-16
    [1] => 2013-07-23
    [2] => 2013-07-30
    [3] => 2013-08-06

)

我想通过下面的特殊character.given输出连接两个数组元素值:

Array
(
    [0] => 2013-07-09 : 2013-07-16
    [1] => 2013-07-16 : 2013-07-23
    [2] => 2013-07-23 : 2013-08-30
    [3] => 2013-08-30 : 2013-08-06

)

尝试array_map这样

$combined = array_map(function($a, $b) { return $a . ' : ' . $b; }, $array1, $array2));
