Question

First Array

[0] => Array
    (
        [name] => Car
        [selected] => 1
    )

[1] => Array
    (
        [name] => Boat
        [selected] => 1
    )

[2] => Array
    (
        [name] => Bike

    )

[3] => Array
    (
        [name] => Tank
    )

[4] => Array
    (
        [name] => Aircraft
    )

第二阵列：

 [0] => Array
    (
        [name] => Boat
        [code] => PLA


    )

[1] => Array
    (
        [name] => Car
        [code] => GTO


    )

所以我需要的是创建包含第一个数组的所有值的新数组，但'selected'条目需要按第二个数组的顺序排列。

所需数组：

[0] => Array
        (
            [name] => Boat
            [selected] => 1
        )

    [1] => Array
        (
            [name] => Car
            [selected] => 1
        )

    [2] => Array
        (
            [name] => Boat

        )

    [3] => Array
        (
            [name] => Tank
        )

    [4] => Array
        (
            [name] => Aircraft
        )

Answer 1

foreach($second as $k => $v) if(isset($v['selected')) $selected[$v['name']] = $v;
foreach($first as $k => $v){
   $Desired[]['name'] = $v['name'];
   if(isset($selected[$v['name']])) $Desired[]['selected'] = 1;
}

Answer 2

$desiredArray = array();
$checkArray = array();
$arrayToAdd =array();
foreach ($secondArray as $item)
{
    foreach($firstArray as $item2)
    {
        if($item2['name'] == $item['name'] && $item2['selected'])
        {
            $n = count($desiredArray);
            $desiredArray[$n]['name'] = $item['name'];
            $desiredArray[$n]['selected'] = 1;
            $checkArray[] = $item['name'];
        }               
    }
}
foreach($firstArray as $item)
{
    if(!in_array($item['name'], $checkArray))
    {
        $desiredArray[]['name'] = $item['name'];
    }
}

试试这个，我不能说我为此感到骄傲，但它可能只是做你需要的。此代码假定第一个和第二个数组都具有相应的名称字段。我没有对此进行过广泛测试，但如果您需要，请随时使用。

Answer 3

所以，让我直截了当，以便我真的可以尝试回答你的问题：

您的目标是确保“第一个”数组中的选定项目的排序方式与“第二个”数组相同。所以你想要一个不同顺序的相同数组值，那个顺序是“第二个”数组中指定的顺序？
