可以用 range 输出 11111 到 55555 的数组,再判新断数组元素有没含有其他的数字,过滤得到新数组
class Num
{
public $array;
public $count;
public $unique;
public $diff;
public $exec;
public function __construct($array)
{
sort($array);
$this->array = $array;
$this->count = count($array);
$this->unique = array_unique($array);
$this->diff = array_diff(range(0, 9), $this->unique); //得到差集
$this->exec = implode('|', $this->diff); // 匹配字符 6|7|8
}
public function soft()
{
$low = str_pad($this->array[0], $this->count, $this->array[0]);
$high = str_pad(end($this->array), $this->count, end($this->array));
$range = range($low, $high);
$str = array_map(function ($a) {
if (preg_match('/' . $this->exec . '/', $a)) {
# 如果匹配到差集的数字,则不输出
} else {
return $a;
}
}, $range);
return array_values(array_filter($str));
}
}
$array = [1, 2, 4, 5, 6];
$a = new Num($array);
print_r($a->soft());
