我如何将这个阵列分成两个？

Question

我有这个数组。

Array
(
    [name] => Array
        (
            [isRequired] => 1
            [isBetween] => 1
            [isAlphaLower] => 
            [isLength] => 
        )

    [email] => Array
        (
            [isEmail] => 1
        )

    [pPhone] => Array
        (
            [isPhone] => 
        )

)

我想将数组拆分为两个。

1。所有布尔值为true的数组

Array
(
    [name] => Array
        (
            [isRequired] => 1
            [isBetween] => 1
        )

    [email] => Array
        (
            [isEmail] => 1
        )

)

2。所有布尔值为false的数组

Array
(
    [name] => Array
        (
            [isAlphaLower] => 
            [isLength] => 
        )

    [pPhone] => Array
        (
            [isPhone] => 
        )
)

我该怎么做？

谢谢..

Answer 1

1. 初始化两个新数组
2. 预先输入数组
3. foreach每个输入数组条目的内部数组
4. 根据设置两个新数组中的一个或另一个的值
5. 进行。

示例：

$arrayTrue = $arrayFalse = arrray(); # 1
foreach($arrayInput as $baseKey => $inner) # 2
    foreach($inner as $key => $value) # 3
        if ($value) $arrayTrue[$basekey][$key] = $value; # 4
        else $arrayFalse[$basekey][$key] = $value;

Answer 2

function is_true($var) {
    return $var;
}
function is_false($var) {
    return !$var;
}

$result_true = array();
$result_false = array();
foreach ($array as $k => $a) {
    $result_true[$k] = array_filter($a, 'is_true');
    $result_false[$k] = array_filter($a, 'is_false');
};

或

$result_true = array();
$result_false = array();
foreach ($array as $k => $a) {
    $result_true[$k] = array_filter($a);
    $result_false[$k] = array_filter($a, function ($x) { return !$x; } );
};

Answer 3

由于您的数组是2级数组，因此您需要使用2个循环。

$trueValues = array();
$falseValues = array();
foreach($input AS $key=>$firstLevelValue) {
    foreach($firstLevelValue AS $key2=>$secondLevelValue)  {
        if ($secondLevelValue)
            $trueValues[$key][$key2] = $secondLevelValue;
        else
            $falseValues[$key][$key2] = $secondLevelValue;
    }
}

3级数组将是：

$trueValues = array();
$falseValues = array();
foreach($input AS $key=>$firstLevelValue) {
    foreach($firstLevelValue AS $key2=>$secondLevelValue)  {
        foreach($secondLevelValue AS $key3=>$thirdLevelValue)  {
            if ($thirdLevelValue)
                $trueValues[$key][$key2][$key3] = $thirdLevelValue;
            else
                $falseValues[$key][$key2][$key3] = $thirdLevelValue;
        }
    }
}
