如何缩短`if-statement` [英] How to shorten `if-statement`

问题描述

我的foreach循环中有一个if语句.条件是大约125个字符长.还有其他方法可以缩短此时间吗?

I have an if statement in my foreach loop. The condition is about 125 characters long. Are there other ways to shorten this?

if ($col == 'foo' || $col == 'bar' || $col == 'baz' || $col == 'fubar' || $col == 'spam' || $col == 'eggs') {
    continue;
} 

注意:很抱歉，条件值家伙'a'，'b'，...的意思是各种各样的字符串.

NOTE: sorry for the confusion on the condition values guys, 'a', 'b', ... were meant to be various strings.

推荐答案

首先将所有元素存储在单个维度数组中，在您的情况下，它将类似于:

Store all elements in single dimension array first, in your case this will be look like:

$array = array('a','b','c','d','e','f');

然后使用内置函数in_array()中的php来检查$ col是否存在于数组中，在您的表中看起来像这样:

Then use php in built function in_array() to check whether $col exists in array, in your this looks like:

in_array($col, $array);

完整代码:

$array = array('a','b','c','d','e','f');
if(in_array($col, $array)) {
    continue;
}
