如果条件中没有多个运算符，请使用stristr匹配单个数组中的任何值 [英] Use stristr to match any value in array in a SINGLE if condition without multiple operators

问题描述

我在编码PHP时非常有能力，尽管我遇到一种情况，我想知道是否可以使用stristr匹配 SINGLE 中的数组中的任何值(如果有条件) .我不需要/想要一个类，一个专用函数或任何超级复杂的东西，也不需要做任何复杂的事情，例如尝试匹配特殊字符，我只是觉得我可能已经错过了php.net上有用的东西.

I'm pretty capable when coding PHP though I just came across a situation where I wondered if it would be possible to use stristr to match any value in an array inside a SINGLE if condition. I don't need/want a class, a dedicated function or anything super-complex nor am I doing anything complex such as trying to match special characters, I just think I may have missed something useful over at php.net.

一般概念...

if (stristr($search_this,$array_with_values)) {echo 'a match was found';}

...或等于什么(即使这不起作用)...

...or what would amount to (even though this does not work)...

if (stristr($search_this,array('string1','string2'))) {echo 'a match was found';}

...我可能会尝试在常规句子/字符串中找到字符串'apple'，'orange'，'banana'.

...I might try to find the strings 'apple','orange','banana' in a regular sentence/string.

我可以在if条件之外定义数组.

I can define the array outside of the if condition.

我的主要目标是在条件不多的情况下使用多个运算符，例如&&或||.

My main goal is to simply not have numerous if conditions or use multiple operators such as && or ||.

所以我不想有多个||.运营商可能会这样...

So I do not want to have multiple || operators like this if possible...

if (
stristr($search_this_string,'string1') || 
stristr($search_this_string,'string2') || 
stristr($search_this_string,'string3')
) {echo 'a match was found';}

我不介意在if条件之前/之外放置数组，尽管我希望能够将所有其他条件都放在单个if条件之内.

I don't mind having the array before/outside of the if condition though I want to be able to fit everything else inside of a single if condition.

推荐答案

我怀疑这是高性能的，但是如果您正在寻找一种外观简单的单线纸:

I doubt this is performant, but if you are looking for a reasonably simple-looking one-liner:

if( str_ireplace(array('string1', 'string2'), '', $str) != $str )
{
  echo 'a match was found';
}
