介绍
您可以轻松获得这样的组合：
echo "<pre>";
$test = ["test_1","test_2","test_3"];
// Get Combination
$return = uniqueCombination($test);
//Sort
sort($return);
//Pretty Print
print_r(array_map(function($v){ return implode(",", $v); }, $return));
function uniqueCombination($in, $minLength = 1, $max = 10) {
$count = count($in);
$members = pow(2, $count);
$return = array();
for($i = 0; $i < $members; $i ++) {
$b = sprintf("%0" . $count . "b", $i);
$out = array();
for($j = 0; $j < $count; $j ++)
$b{$j} == '1' and $out[] = $in[$j];
count($out) >= $minLength && count($out) <= $max and $return[] = $out;
}
return $return;
}
输出
Array
(
[0] => test_1
[1] => test_2
[2] => test_3
[3] => test_1,test_2
[4] => test_1,test_3
[5] => test_2,test_3
[6] => test_1,test_2,test_3
)
问题
它们是关于1,048,576组合的，我相信这不是你想要的那种数组我会建议基于条件的组合而不是所有可能的组合
例子
// Game Conditions
$game = new Game();
$game->addCondition(new Condition(new Level(1), new Kill(30)));
$game->addCondition(new Condition(new Level(2), new Map(1), new Kill(10)));
$game->addCondition(new Condition(new Level(3), new Grunt(10)));
$game->addCondition(new Condition(new Level(4), new Knife(1), new Ak47(1)));
$game->addCondition(new Condition(new Level(5), new Grenade(1), new Combo(7)));
$game->addCondition(new Condition(new Level(6), new Kill(100), new Blow(10), new Stab(10)));
$game->addCondition(new Condition(new Level(7), new Herb(10), new Medipack(1), new Map(1), new Artwork(1)));
$game->addCondition(new Condition(new Level(8), new Grenade(20),new Artwork(5)));
// User Starts Game
$user = new User($game);
$user->task(new Map(1));
$user->task(new Herb(5));
$user->task(new Kill(10));
$user->task(new Kill(10));
$user->task(new Herb(10));

$user->task(new Artwork(1));
$user->task(new Grenade(1));
$user->task(new Combo(10));
$user->task(new Blow(10));
$user->task(new Stab(5));
$user->task(new Blow(10));
$user->task(new Stab(5));
$user->task(new Stab(5));
printf("\n<b>Total Point %s",number_format($user->getPoint(),0));
