我有以下数据结构;PHP - 重构/改进Ifs

Array ([0] => Array ([suit] => c [rank] => A) 
     [1] => Array ([suit] => d [rank] => A))

我想测试这些卡是否具有某些值并显示相应的消息;

if (
    (($hand[0]['rank'] == "A") && ($hand[1]['rank'] == "A")) 
|| (($hand[0]['rank'] == "K") && ($hand[1]['rank'] == "K")) 
|| (($hand[0]['rank'] == "Q") && ($hand[1]['rank'] == "Q")) 
|| (($hand[0]['rank'] == "A") && ($hand[1]['rank'] == "K")) 
|| (($hand[0]['rank'] == "K") && ($hand[1]['rank'] == "A"))  
    ) { 
    echo "Action: Raise pre-flop. Re-raise if already raised.<br />\n"; 
} 
if (
     (($hand[0]['rank'] == "7") && ($hand[1]['rank'] == "7")) 
    || (($hand[0]['rank'] == "A") && ($hand[1]['rank'] == "J") && ($hand[0]['suit'] == $hand[1]['suit'])) 
    || (($hand[0]['rank'] == "J") && ($hand[1]['rank'] == "Q") && ($hand[0]['suit'] == $hand[1]['suit'])) 
    || (($hand[0]['rank'] == "10") && ($hand[1]['rank'] == "J") && ($hand[0]['suit'] == $hand[1]['suit'])) 
     ) { 
     echo "Action: Worth a call pre-flop (provided no-one has raised).<br />\n"; 
    }

我已通过删除一些条件简化了IF。

任何人都可以提出一个更好的方法来做到这一点？

回答：

也许尝试使用in_array（）方法

php.net in_array()

回答：

尝试使用这样的引用：

$rank0 =& $hand[0]['rank']; 
$rank1 =& $hand[1]['rank']; 
if (
($rank0 == "A" && $rank1 == "A") 
|| (...)

只是，作为第一步代码最小化
