Question

我有两个数组：（＆＃39; admin＆＃39;，＆＃39; admin2＆＃39;，＆＃39; admin3＆＃39;可能太多了，名称也可能不同于＆＃39; admin＆＃39;）

$old = array(
array('admin'=>array('a'=>'aaa','b'=>'bbb')),
array('admin2'=>array('c'=>'ccc','d'=>'ddd'))
);

$new = array(
array('admin2'=>array('e'=>'eee','f'=>'fff')),
array('admin3'=>array('g'=>'ggg','h'=>'hhh'))
);

我希望从以上两个数组中获取此数组：（新阵列中包含来自新阵列的两个PLUS类似键中的所有不同键）

$output = array(
array('admin'=>array('a'=>'aaa','b'=>'bbb')),
array('admin2'=>array('e'=>'eee','f'=>'fff')),
array('admin3'=>array('g'=>'ggg','h'=>'hhh'))
);

Answer 1

// Remove one level of array to make arrays as ['admin'=>array, 'admin2'=>array]
$old1 = call_user_func_array('array_merge', $old);
$new1 = call_user_func_array('array_merge', $new);
// Make replacement
$ready =  array_replace($old1, $new1);
// Return level making every item as array 
$result = array();
foreach($ready as $k=>&$v) 
    $result[] = array($k=>$v);
print_r($result);

此代码将解决您的问题：

<?php 
$array1 = array(
    array('admin'=>array('a'=>'aaa','b'=>'bbb')),
    array('admin2'=>array('c'=>'ccc','d'=>'ddd'))
);

$array2 = array(
    array('admin2'=>array('e'=>'eee','f'=>'fff')),
    array('admin3'=>array('g'=>'ggg','h'=>'hhh'))
);

$output = $array1; ///merge array1 into output array

foreach($array2 as $key => $val)
{
    $is_present_key = false;
    $first_key = key($val);
    foreach($output as $k => $v)
    {
        if(array_key_exists($first_key,$output[$k])) ////check if key exit in $output array
        {
            $output[$k] = $val; ///push new value if key exists in $output
            $is_present_key = true;
        }
    }
    if($is_present_key == false)///skip for duplicate of new values if key exists in $output 
    {
        $output[] = $val;
    }
}

echo "<pre>"; print_r($output);

?>

这会给你：

Array
(
    [0] => Array
        (
            [admin] => Array
                (
                    [a] => aaa
                    [b] => bbb
                )

        )

    [1] => Array
        (
            [admin2] => Array
                (
                    [e] => eee
                    [f] => fff
                )

        )

    [2] => Array
        (
            [admin3] => Array
                (
                    [g] => ggg
                    [h] => hhh
                )

        )
