Question

我获取值表单日期范围并使用explode到数组错误行whereBetween

$range = Input::get('daterange') ;
    $date = explode('to', $range);
    //dd($date);

    $temp = Temps::select('temp')
        ->orderBy('date_temp', 'asc')
        ->whereBetween('date_temp',[$date[0], $date[1]])
        ->get()
        ->pluck('temp');

1/1）ErrorException未定义的偏移量：1

Answer 1

您需要更改，因为范围为$range='09/11/2017 - 10/10/2017';。您需要使用-进行拆分

$date = explode('-', $range);

如果您打印$date

Array
(
    [0] => 09/11/2017 
    [1] =>  10/10/2017
)

另请注意，您可以直接传递数据。由于[$date[0], $date[1]接受数组而且whereBetween是数组

，您将获得$date而不是

$temp = Temps::select('temp')
        ->orderBy('date_temp', 'asc')
        ->whereBetween('date_temp',$date)
        ->get()
        ->pluck('temp');

def ip_matches_network(self, network, ip):
    """
    '{:08b}'.format(254): Converts 254 in a string of its binary representation

    ip_bits[:net_mask] == net_ip_bits[:net_mask]: compare the ip bit streams

    :param network: string like '192.168.33.0/24'
    :param ip: string like '192.168.33.1'
    :return: if ip matches network
    """
    net_ip, net_mask = network.split('/')
    net_mask = int(net_mask)
    ip_bits = ''.join('{:08b}'.format(int(x)) for x in ip.split('.'))
    net_ip_bits = ''.join('{:08b}'.format(int(x)) for x in net_ip.split('.'))
    # example: net_mask=24 -> compare strings at position 0 to 23
    return ip_bits[:net_mask] == net_ip_bits[:net_mask]

Answer 2

试试这个：

$date = explode('-', $range);

您试图使用变量中不存在的字符串来展开变量，这就是为什么在$date

中仅使用一个数组获取相同变量的原因

未定义的偏移：1个错误的日期范围爆炸数组
