我有两个数组，我只是想在一个函数中合并在一起：

$var1=array();
$myInputVar=array();
$var1['something']['secondary_something'][]="foo1";
$var1['something']['secondary_something'][]="foo2";
$var1['something']['secondary_something'][]="foo3";

$myInputVar['something']['secondary_something'][]="foo4";
$myInputVar['something']['secondary_something'][]="foo5";

function something(&$array_, $array_new) {
   $array = array_merge($array_ , $array_new); 

    print_r($array);//for debugging

}   
something($var1, $myInputVar);

现在打印：

Array ( [something] => Array ( [secondary_something] => Array ( [0] => foo1 [1] => foo2 [2] => foo3 ) ) )

当我期待：

Array ( [something] => Array ( [secondary_something] => Array ( [0] => foo1 [1] => foo2 [2] => foo3 [3] => foo4 [4] => foo5) ) )

我也试过：

$array = $array_ + $array_new;

仍然没有打印出我的期望。

我有一种感觉，我误解了array_merge()函数的目的，这就是为什么它没有返回我期望它返回的结果。

有任何想法吗？

试试array_merge_recursive()。

array_merge将从左到右工作。在你的情况下：

$array_['something']['secondary_something']

将被覆盖

$array_new['something']['secondary_something']

您可以执行以下操作：

function something(&$array_, $array_new) {
    $array = array_merge($array_ , $array_new); 
    return $array;
}

$var1['something']['secondary_something'] = something($var1['something']['secondary_something'], $myInputVar['something']['secondary_something']);

否则，您将需要创建一个知道关联键并将适当组合数组的函数。

function something(&$array_, $array_new) {
    foreach ($array_new as $val)
        foreach ($val as $val2)
            foreach ($val2 as $val3)
                array_push($array_['something']['secondary_something'], $val3);
    print_r($array_);//for debugging
}
