Question

如何获取链接文字（如降价）。说一些类型

class PricesTable[PriceList <: HList](prices: PriceList)(implicit lubC: LUBConstraint[PriceList, Price[_]]) {
  def priceFor[C <: Country](implicit selector: Selector[PriceList, Price[C]]): Price[C] =
    prices.select[Price[C]]
}

结果如下：

(Google)[https://google.com]

这是我目前的职能：

<a href="https://google.com">Google</a>

如果有人输入https://google.com，则会返回：

function MakeUrls($str)
{
    $find=array('`((?:https?|ftp)://\S+[[:alnum:]]/?)`si','`((?<!//)(www\.\S+[[:alnum:]]/?))`si');

    $replace=array('<a href="$1" target="_blank"> $0</a>', '<a href="http://$1" target="_blank">$1</a>');

    return preg_replace($find,$replace,$str);
}

Answer 1

function makeURLs($str) {
  $explode = explode(")[", $str);
  if (sizeof($explode) !== 2) return false; //failsafe stuff

  $name = substr($explode[0], 1, strlen($explode[0]));  //remove the (
  $url = substr($explode[1], 0, strlen($explode[1])-1); //remove the ]

  return "<a href=\"$url\" target=\"_blank\">$name</a>";
}

应该这样做
