Question

有没有办法将两维数组转换为单维数组而不使用php中的foreach循环。

下面是实际的数组

Array
(
    [0] => Array
        (
            [male] => male
            [female] => female
        )
    [1] => Array
        (
            [male] => male1
            [female] => female1
        )
)

输出就像

Array
(
    [0] = > male
    [1] = > female
    [2] = > male1
    [3] = > female1
)

Answer 1

您可以使用reduce并使用array_merge

$array = array( ... ); //Your array here
$result = array_reduce($array, function($c,$v){
    return array_merge(array_values($c),array_values($v));
}, array());

这将导致：

Array
(
    [0] => male
    [1] => female
    [2] => male1
    [3] => female1
)

Answer 2

循环遍历多维数组并将结果存储在新数组变量$ newArray中。

$newArray = array();
foreach($multi as $array) {
 foreach($array as $k=>$v) {
  $newArray[$k] = $v;
 }
}

将二维数组转换为单维数组而不使用PHP
