Question

这是我的旧阵列。

$oldarray = Array
    (
        [0] => http://test.to/getac/l4p0y6ziqt9h
        [mock] => stdClass Object
            (
                [0] => http://test.to/getae/vidzichawal1
                [1] => http://test.to/getae/vidzi6
                [4] => http://test.to/getae/1x5fbr9t64xn
                [2] => http://test.to/getae/vidzi7
            )

    )

我想与这个新数组合并：

$newarray =  Array
    (
        [mock] => Array
            (
                [0] => http://test.to/getae/vidzichawal2
            )

    )

我正在通过array_merge_recursive($oldarray, $newarray);

合并数组

结果如下：

Array
(
    [0] => http://test.to/getac/l4p0y6ziqt9h
    [mock] => Array
        (
            [0] => http://test.to/getae/vidzi5
            [1] => http://test.to/getae/vidzi6
            [4] => http://test.to/getae/1x5fbr9t64xn
            [2] => http://test.to/getae/vidzi7
            [0] => http://test.to/getae/vidzichawal1
        )
);

所有的东西都运行良好，但有一个问题，你可以看到结果有双0键，当我在循环中使用此链接仅1链接反向0我想自动设置此键0 1 2 3 4 5 6并在合并后继续。

我希望你理解我想要的东西谢谢

Answer 1

使用array_merge()

<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);
?>

以上示例将输出：

Array
(
    [color] => green
    [0] => 2
    [1] => 4
    [2] => a
    [3] => b
    [shape] => trapezoid
    [4] => 4
)

注意您不能拥有重复的密钥！

使用array_merge_recursive()

的示例

<?php
$oldarray = array('http://test.to/getac/l4p0y6ziqt9h', 'mock' => array('http://test.to/getae/vidzichawal1', 'http://test.to/getae/vidzi6', 'http://test.to/getae/1x5fbr9t64xn', 'http://test.to/getae/vidzi7'));
$newarray = array('mock' => array('http://test.to/getae/vidzichawal2'));

$result = array_merge_recursive($oldarray, $newarray);

var_dump($result);
?>

输出

array (size=2)
  0 => string 'http://test.to/getac/l4p0y6ziqt9h' (length=33)
  'mock' => 
    array (size=5)
      0 => string 'http://test.to/getae/vidzichawal1' (length=33)
      1 => string 'http://test.to/getae/vidzi6' (length=27)
      2 => string 'http://test.to/getae/1x5fbr9t64xn' (length=33)
      3 => string 'http://test.to/getae/vidzi7' (length=27)
      4 => string 'http://test.to/getae/vidzichawal2' (length=32)
