如何在Codeigniter中将两个对象的值合并为一个对象

Question

我有一个对象数组，所有对象都是同一对象。 但是最后我需要将一个对象的所有这些值放入单个对象中。这些是我的对象。

Array

Answer 1

合并之前或之后，您只需要删除重复的值即可。

$array1 = [ 
        "modules" => [ 
            0 => 2, 1 => 4
            ], 
        "submodules" => [
            "3m" => [
                0 => "create", 1 => "read"
                ], 
            "4m" => [0 => "create", 1 => "read"
                ]
        ]
    ];

$array2 = [ 
    "modules" => [ 
        0 => 1, 
        1 => 3
        ], 
    "submodules" => [
        "1m" => [
            0 => "create", 1 => "read"
            ], 
        "10m" => [
            0 => "create", 1 => "read"
            ]
    ]
];

$merged = array_merge_recursive($array1, $array2);
print_r($merged);

Array ( [modules] => Array ( 
[0] => 2 [1] => 4 [2] => 1 [3] => 3 
) 
[submodules] => Array ( 
[3m] => Array ( [0] => create [1] => read 
    ) 
[4m] => 
    Array ( [0] => create [1] => read 
        ) 
[1m] => Array (
    [0] => create [1] => read 
    ) 
[10m] => Array ( 
[0] => create [1] => read 
    ) 
) 

）

如果您不想使用array_merge，则可以使用以下解决方法：

$global; //your array
$merged = array(); //the array you want with the merged objects
foreach ($global as $k => $object) {
    foreach ($object as $key => $values) {
        foreach ($values as $val)
            $merged[$key][] = $val;
    }
}
