How do i split this array into two?

I have this array.

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

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

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

)

i want to split the array into two.

1. array with all boolean value true

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

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

)

2. array with all boolean value false

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

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

How do i do it?

As your array is a 2 level array, you will need to use 2 loops.

$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;
    }
}

A 3 level array would be:

$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;
        }
    }
}

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');
};

or

$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; } );
};

  1. initialize the two new arrays
  2. foreach the input array
  3. foreach the inner array of each input array entry
  4. according to the value set the one or the other of the two new arrays
  5. done.

Example:

$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;
