如何通过特殊的charcter连接php中的两个数组元素值？

i have two arrays given below

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

)

i want to concatenate two array element values by special character.given output below:

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

)

3 个解决方案

#1

Try with array_map like this

尝试使用这样的array_map

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

#2

$a1 = new ArrayIterator($array1);
$a2 = new ArrayIterator($array2);

$it = new MultipleIterator;

$it->attachIterator($a1);

$it->attachIterator($a2);

foreach($it as $e) {

        $array3[] = $e[0]." : ".$e[1]);
}

do this , $combined_array is your answer

这样做，$ combined_array就是你的答案

$array1 = Array
(
    [0] => 2013-07-09
    [1] => 2013-07-16
    [2] => 2013-07-23
    [3] => 2013-07-30
);
$array2 = Array
(
    [0] => 2013-07-16
    [1] => 2013-07-23
    [2] => 2013-07-30
    [3] => 2013-08-06

);
$combined_array = array();
foreach($array1 as $key=>$value)
{
    $combined_array[$key]=$value." : ".$array2[$key];
}
