PHP多维数组合并一个数组内的两棵树怎么样？

Question

我想在php中的md数组中将两个树合并为多维到一棵树：

$ array [1] = Array

            [0] => a
            [1] => b
            [2] => c

$ array [2] = Array

            [0] => d
            [1] => e
            [2] => f  

结果：

$ array [1] = Array

            [0] => ad
            [1] => be
            [2] => cf

Answer 1

你可以试试这个：

<?php

foreach($array[1] as $key => $value)
{
  $array[1][$key] = $value.$array[2][$key];
}

?>

Answer 2

We can use array function to solve this Problem Like this :

$array = array('a','b','c');
$array2 = array('d','e','f');
$c = array_combine($array, $array2);
foreach($c as $key=>$value){
   $data[] = $key.$value;
}
print_r($data);
