Answer 1

initialize the two new arrays
foreach the input array
foreach the inner array of each input array entry
according to the value set the one or the other of the two new arrays
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;

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');
};
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; } );
};

Answer 3

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;
}
}
}
