Question

我们有这个数组，

<?php
    $arr1=array(0,1,2,3);
    $arr2=array(array(0,1,2,3));

    array_push($arr1,$arr2);
    echo "<pre>";
    print_r($arr1);
?>

输出：

Array
(
    [0] => 0
    [1] => 1
    [2] => 2
    [3] => 3
    [4] => Array
        (
            [0] => Array
                (
                    [0] => 0
                    [1] => 1
                    [2] => 2
                    [3] => 3
                )

        )

)

预期：

Array
(
    [0] => 0
    [1] => 1
    [2] => 2
    [3] => 3
    [4] => 0
    [5] => 1
    [6] => 2
    [7] => 3
)

我们尝试过 array_push（$ arr1，$ arr2）

Answer 1

没有内置功能。但是，您可以使用递归函数或递归迭代器轻松完成此操作，例如：

$arrayIterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($array2));
foreach($arrayIterator as $value) {
    $array1[] = $value;
}

它可以在没有预告的情况下完成：

$flatArray = iterator_to_array(
    new RecursiveIteratorIterator(new RecursiveArrayIterator($array2)),
    false
);
$array1 = array_merge($array1, $flatArray);

Answer 2

试试这个：

$arr1=array(0,1,2,3);
$arr2=array(array(0,1,2,3));

$result = array_merge($arr1, $arr2[0]);
echo "<pre>";
print_r($result);

你也可以这么做：

for($i=0;$i<count($arr2[0]);$i++)
{
    array_push($arr1,$arr2[0][$i]);
}
echo "<pre>"; 
print_r($arr1);

Answer 3

＆＃34;动态＆＃34;的解决方案具有array_merge_recursive和array_walk_recursive函数的多维数组：

$arr1 = array(0,1,2,3);
$arr2 = array(array(0,1,2,3), array(0 => array(4,5), 2));
$merged = array_merge_recursive($arr1,$arr2);

$result = [];
array_walk_recursive($merged, function($v,$k) use(&$result){
    $result[] = $v;
});
var_dump($result);

输出：

Array
(
    [0] => 0
    [1] => 1
    [2] => 2
    [3] => 3
    [4] => 0
    [5] => 1
    [6] => 2
    [7] => 3
    [8] => 4
    [9] => 5
    [10] => 2
)

Answer 4

array_merge($arr1,$arr2);将有效。

Answer 5

我编写的函数从任何多维数组中获取值，并在创建结果数组时使用它：

<?php

 $arr1=array(0,1,2,3);
 $arr2=array(array(0,1,2,3));
 $arr3=array(array(array(0,1,2,3)));


function getValues($array)
{
    $result = array();

    if(isset($array[0]) && is_array($array[0]))
       $result = getValues($array[0]);
    else
    {
        $result = $array;
    }

    return $result;   
}


$arr1Values = getValues($arr1);
$arr2Values = getValues($arr2);
$arr3Values = getValues($arr3);

$result = $arr1Values;

foreach($arr2Values as $value)
{
    $result[] = $value;
}

foreach($arr3Values as $value)
{
    $result[] = $value;
}

echo '<pre>';
print_r($result);
echo '</pre>';

结果是：

Array
(
    [0] => 0
    [1] => 1
    [2] => 2
    [3] => 3
    [4] => 0
    [5] => 1
    [6] => 2
    [7] => 3
    [8] => 0
    [9] => 1
    [10] => 2
    [11] => 3
)
